What to Choose - Urography or MRI of the Kidneys

To assess the function of the urinary system of the body and identify its diseases, the doctor will offer you several research options - this will be either CT, ultrasound, urography or MRI of the kidneys. But what to choose? Let us dwell on the last two methods. The human urinary system includes the ureters, renal pelvis, bladder, and prostate. The complexity of the device of this system causes a large number of research methods.

Urography or MRI of the kidney: research principle

Renal urography, unlike MRI, is an x-ray examination method. With the passage of urography by MRI Scan Centres in East Delhi, a contrast agent is injected into the patient, which is subsequently excreted through the kidneys. There are three types of urography:

  • Overview, without contrast;
  • Excretory, take a picture sometime after the introduction of contrast;
  • Intravenous, contrast is injected into a vein, after which 3–4 shots are taken at the second, fifth and seventh minutes, which allows us to estimate the rate at which contrast is removed.

Normally, contrast agents should not accumulate in the tissues or be modified but should be well excreted through the kidneys. Usually, use radiopaque preparations based on iodine.

Urography is prescribed for:

  • Infectious processes in the kidneys;
  • Injuries;
  • Suspected neoplasm;
  • Urolithiasis;
  • Developmental abnormalities;
  • Kidney diseases (nephroptosis, hydronephrosis).

Indications for kidney MRI are almost the same as for urography, but this method of research is not X-ray but MRI test labs in Delhi uses a magnetic field to take pictures, which is practically harmless to the body. Also, with MRI, layer-by-layer images of the organ are obtained, which are then combined into a three-dimensional image using a computer program. Tomography can also be performed with or without a contrast, which contains gadolinium salts.

Urography or MRI: Advantages and Disadvantages

Both urography and MRI can reveal some pathologies of the kidneys, as well as a violation of their excretory function. So, with their help, you can detect:

  • Hydronephrosis of one kidney or both;
  • Kidney prolapse (nephroptosis);
  • Developmental abnormalities (horseshoe kidney);
  • Stones in the pelvis, ureters;
  • Ureteral trauma;
  • Benign, malignant tumors.

But, unlike MRI, urography gives a picture in which the shadows of the organs overlap, which does not always make possible the successful detection of pathology. Especially often get a good picture to interfere with gases in the intestine.

Also, the urography has the following number of disadvantages:

  • Low quality of the image, which does not allow to look at tiny formations (MRI visible education less than 1 cm);
  • Irradiation with ionizing rays (in some cases, it is quite high, since several pictures are taken during urography);
  • The inability to qualitatively study the structure of the kidneys;
  • High allergic of iodine-containing contrast (as compared with gadolinium-based preparations);
  • Urography cannot be performed on children.
What is the Difference between Magnetic Resonance Imaging and Duplex Scanning?

MRI or duplex scanning is widely used in clinical practice for the diagnosis of diseases affecting blood vessels - veins or arteries. Choosing which of these techniques to include in the examination program, the MRI scan centers in New Delhi makes a start from the patient's age, clinical picture, characteristics of the organism and other factors. To objectively answer the question of how duplex scanning differs from MRI, we will pay attention to the principles on which these methods are based.

MRI or duplex scanning: which procedure to choose?

Magnetic resonance imaging is based on the phenomenon of nuclear magnetic resonance, which occurs when exposed to atomic nuclei (most often hydrogen) with a certain combination of electromagnetic pulses. After registration of the electromagnetic response of atoms, computer processing of the obtained parameters is performed and their subsequent transformation into a detailed image of the zone of interest.

Duplex scanning combines as many as two diagnostic methods: ultrasound diagnostics and dopplerography. During the procedure, an ultrasound examination of the target area is performed with a parallel analysis of the velocity parameters of blood flow.

When an MRI or duplex scan is shown

Both methods - MRI or duplex vascular scanning - allow you to diagnose a wide range of vascular pathologies. It is important to note that with the help of MRI scan, you can identify the pathological process at an early stage when any symptoms are mild or absent.

Indications for MRI of blood vessels are:

  • The presence of symptoms of vegetative dystonia;
  • Coronary heart disease;
  • Dizziness, tinnitus, frequent high-intensity headaches;
  • Suspected vascular stenosis, congenital anomalies, thrombosis of the cerebral veins and sinuses;
  • Assessment of the state of blood circulation.

Often, MR-diagnostics of the vascular system is performed after the preliminary injection of contrast, which significantly improves the visualization of the zone of interest.

Examination by duplex scanning is prescribed for the diagnosis of the following pathologies:

  • Obliterating endarteritis of the lower extremities;
  • Arteriovenous fistulas, vascular malformations or aneurysms;
  • Varicose veins;
  • Diabetic foot syndrome;
  • Lesions of cerebral vessels

Duplex scanning is used to assess the peripheral blood circulation, functional parameters of blood flow, vascular wall condition and patency. Duplex scanning, like MRI, is safe for health because it does not imply an ionizing effect or radiation load on the human body. In comparison with tomography, this manipulation is not associated with intravenous administration of contrast; it requires significantly less financial and time costs.

When determining whether you will undergo an MRI or a duplex scan, it is important to take into account contraindications to the examination and MRI scan discount. The duplex scanning method is practically devoid of them.

Contrast enhancement is excluded at any stage of pregnancy, with kidney damage, hematopoietic anemia, and individual intolerance to contrast. What to choose- MRI or duplex scanning- is decided by a specialist, based on anamnestic data and medical documentation provided.

MRI Scan during Pregnancy

MRI of the uterus is one of the imaging methods that can be used during pregnancy. The question of the safety of the method and its impact on the health of the baby worries the future mother most of all. Do I need to undergo MRI of the uterus during pregnancy, or is it better to postpone the examination until the birth?

The essence of the method

To obtain an image in magnetic resonance imaging using a magnetic field. This is different from computed tomography, which uses ionizing radiation that negatively affects growing cells. Under the control of the magnetic field, the hydrogen atoms change the vector direction to the opposite, which is accompanied by the release of energy, the amount of which is recorded by the system of data collection apparatus. Since the content of hydrogen atoms in the tissues is very different, then the amount of energy released will be different. In the resulting image, the neighboring structures have the form of areas with different brightness, which allows the MRI test labs in Delhi to conclude their condition.

The first group includes:

  • Any abnormalities in the structure of the fetal organs established by ultrasound;
  • Burdened family history - the presence of severe developmental abnormalities in previous children, close relatives;
  • Changes in laboratory tests, indicating possible impairments in the growth and development of the child;
  • The impact of factors that adversely affect pregnancy;
  • The likelihood of traumatic injury to the fetus and amniotic structures;
  • Suspicion of intrauterine infection;
  • Multiple pregnancies.

Not long ago, the MRI of the uterus during pregnancy was hindered by the movements of the child, but with the help of modern equipment, you can get high-quality images at any time.

Indications for MRI of the uterus during pregnancy

MRI of the uterus during pregnancy allows you to see the organs of the small pelvis - the uterus, appendages, bladder and rectum, fetus and amniotic structures. In this regard, the indications for MRI of the uterus during pregnancy are divided into two groups - from the fetus and the mother.

MRI of the uterus during pregnancy: how safe is it?

As a diagnostic method, magnetic resonance imaging has been used since the early 1980s. During this time, scientists have not received evidence of its negative impact on the child. However, pregnancy remains a relative contraindication to the study. MRI of the uterus during pregnancy is carried out only in cases where the ultrasound technique has completely exhausted its possibilities in a particular case, and the postnatal diagnosis will be inopportune. Also, in the first 12 weeks of pregnancy, when the organs of the fetus are actively laid down, MRI of the uterus is performed only if there are indications that threaten the life of the mother.

Experience shows the value of using MRI for imaging the uterus and pelvic organs in pregnant women. MRI done by MRI scan centre in Noida helps not only to diagnose, but also to make the right decision about carrying a baby, to work out the correct medical tactics and to control its effectiveness.

Some Unique Foods for Strong Bones

Healthy eating isn’t just about ensuring that you are able to stay at a healthy weight and keep your body in good shape; it’s also about looking after yourself from the inside out. The foods that we eat have a huge impact on our health, which is why eating well is so important.

Weak bones can increase the chances of loss of bone density which is ascertained in a Vitamin d deficiency test, one of the many tests which makes for the healthy bones panel.

Eating well is very important for the health of our bones as the food alone is responsible for its strengthening. Let's check out the foods that keep your bone health up and running.

1.       Sardines and salmon- This oily fish is delicious cut up on toast, served with pasta, or as part of a salad. Believe it or not, sardines are rich in a range of nutrients, including both vitamin D and calcium. While just one piece of salmon offers more than 100% of your daily vitamin D needs and is also rich in omega-3 fatty acids.

2.       Spinach - Not a fan of dairy products but still want to ensure that you get your daily calcium hit? Well then, spinach is the ideal food to eat, as it’s packed full of calcium. One cup of spinach (cooked) contains 25% of your suggested daily calcium intake, as well as plenty of fiber, iron and vitamin A.

3.       Sesame Seeds- This is one of the lesser known food that does a lot of benefit to our bones. If you are not a fan of dairy products, it must delight you to know that sesame is a dairy-free source of calcium and also contain magnesium and phosphorus which promote bone health. Sesame, the East Indian annual erect herb is also a rich source of zinc. This makes Zinc an absolutely must-have food since the lower intake of zinc has been linked to osteoporosis.

4.       Green tea- Green tea offers nutritional support for bone health. The further explaining reveals that the green tea are replete with compounds called flavonoids which provide Green and black antioxidant and anti-inflammatory properties. In fact drinking green tea on a regular basis has shoen to increase the bone mineral density. One of the prime reasons for bone loss which culminates into osteoporosis. Therefore a beverage like consuming foods and beverages with antioxidants, such as green tea, is important. Green tea is a very good source of catechins or polyphenols some of the most powerful antioxidants along with epigallocatechin gallate (EGCG), which have been shown to support bone health.

As we discussed the four best foods for strengthening, it is equally important to be aware of the foods that silently deteriorate the bone health. Contrary to the popular belief, alcohol consumption doesn’t only affect your liver. Osteoblasts are the body’s bone building cells which get hindered in its functioning when you booze. It is literally the cause of bone getting weakened due to the fact that it blocks all the calcium nutrients that’s supposed to be in your body. Similarly, sodas can surely provide you respite on a sultry day. But its parameter on health grounds is very low. Soda drinks contain phosphoric acid and this leads to an increase in calcium excretion over time.

Know the Relation between Memory Loss and MRI

If incidents of memory failures are frequent, or if problems of memory and concentration appear early in life, a doctor should be consulted to clarify the causes. Thus, you should go to a specialist when a person suffers mental confusion, has difficulty using or understanding the language, has vision problems, cannot perform daily activities as they normally did due to frequent forgetting, etc.

Initially a detailed study will be carried out with a neurological evaluation and an examination of the cognitive functions and the psychological state of the patient. Often, the doctor can ask specific questions such as when memory failures occur, how often they appear, and what other symptoms occur when they appear, or whether there is a previously diagnosed disease that can cause these problems. These questions help the doctor identify the cause of the memory loss. In many cases, a family history study will also be crucial for diagnosis.

After the first anamnesis, a physical and neurological examination is performed, in which, for example, vision and hearing are reviewed to rule out the possibility that the visual or auditory defect can be mistakenly interpreted as an impairment of memory. Various neuropsychological tests are used, such as the MMSE (Mini Mental State Examination) to quantify the possible cognitive impairment associated with memory deficit. If the doctor thinks that a more complete examination is needed, it may be necessary to consult a neuropsychologist and make other tests more complete, because the problems of language, communication or personal motivations can interfere with the memory.

Thus, depending on the diagnostic suspicion of the doctor as the most likely cause after the first examinations, other tests are carried out, such as magnetic resonance imaging (MRI scan centre in East Delhi), computerized axial tomography (CAT), cerebrospinal fluid analysis and blood tests.

In cases of dementia, tests may be necessary such as: a blood count, a complete hemochemistry, a serology, a chest x-ray, an electrocardiogram, a specific test to determine vitamin B12, folate or the level of thyroid hormones, an examination of the urine or a computed axial tomography of the skull.

The early detection of a memory problem or a cognitive disorder is very important, since it can help to stop or improve the progression of these alterations and that the patient arrives to have a serious and irreversible disability.

In more than 20 years of study, radiologists have discovered that different tissues (brain, bone marrow, liver, blood, etc.) are all shown by using different combinations of pulse techniques. They have also discovered that certain combinations show abnormalities, such as tumors or scars.

When you undergo an MRI scan price in Noida session, a series of different tests are performed. The standards, which are executed for almost all medical conditions, are called T1 and T2 (This depends on the way they measure the relaxation of the magnetic particles).

The types of analysis are constantly being developed, but the type of additional scan that is most frequently used for EM investigations is FLAIR.

The basis of the operation of the RM, is that different types of matter, emit different energy levels, when placed in a magnetic field.

CT Scans to Detect Lung Cancer in Smokers

A low-dose helical computed tomography (CT scan center in Noida) scan is a type of medical test. It is used to detect early signs of lung cancer. If the test detects cancer, treatment can start early.

However, the test is not beneficial for people who smoke little or those who quit smoking more than 15 years ago and is generally not recommended for people under 55 or over 80 years of age. Even people who smoke a lot receive only a small benefit from the test, so you should think twice before taking the test.

Who should consider an analysis for detection?

The CT scan cost in Delhi for lung cancer is usually reserved for people who have the highest risk of developing this cancer, such as the following:

·        Older adults who smoke or were smokers. The analysis for the detection of lung cancer, generally, is offered to people of 55 years or more who smoke or were smokers.

·        People who have smoked a lot for many years. You can consider an analysis to detect lung cancer if you have a history of smoking 1 packet per year for 30 years or more. The pack years are calculated by multiplying the number of packets of cigarettes you smoked per day and the number of years you smoked.

·        People who once smoked a lot but stopped smoking. If you smoked a lot for a long time but have quit smoking, you can consider an analysis for the detection of lung cancer.

·        People with good health in general. If you have serious health problems, you are less likely to benefit from the screening test for lung cancer and are more likely to experience complications in follow-up testing. For this reason, the screening for lung cancer is offered to people who are in good general health.

·        In general, screening is not recommended for those who have poor lung function or other serious conditions that could make surgery difficult. This could include people who need continuous oxygen administration, who have suffered thinning without apparent cause in the past year, who have recently shed blood when coughing or who have undergone chest computed tomography screening in the past year.

·        People with a history of lung cancer. If you have been treated for lung cancer for more than five years, you may consider having an analysis for lung cancer screening.

·        People who have other risk factors for lung cancer can be those who have chronic obstructive pulmonary disease, those with a family history of lung cancer and those who are exposed to asbestos at work.

How long the analysis for detection should be continued?

Not all medical groups agree on how old you can consider stopping the test for lung cancer. In general, continue to perform the annual analysis for the detection of lung cancer until the time when you do not benefit from it, as when you manifest other serious conditions that may leave you too weak to undergo cancer treatment.

What is Breast Ultrasound?

Most women know that from a certain age it is very important to have regular breast exams. Prevention always plays a prominent role, but there are diseases that detect the existence of cancer cells in time and put a rapid treatment completely changes the evolution of them. This happens, for example, in the case of breast cancer.

In addition to the exploration that gynecologists perform in consultation, breast scan cost in Delhi and diagnostic tests are also fundamental as a method of screening, to know if everything is in perfect condition or should be alerted for some reason. The most common are breast ultrasound and mammography. But is the difference between the two known?

What is mammography?

Each one has its peculiarities. The most used for the early detection of breast cancer is mammography, both for asymptomatic women and for those who have lumps, nipple discharge or sinking. It is a technique that, through minimal radiation, shows images of the interior of the woman's breasts. It is so effective that it can show changes in the breast long before the doctor or patient notice it.

Although the protocol in the public health talks about starting to get mammograms from 50 years, it is recommended that from 40 women take this test every year. Obviously, in women with a history of breast or ovarian cancer, it is necessary to begin screening before that age.

The best time to get a breast scan cost in Delhi is one week after having had the period. In this way the days in which the breasts are more swollen and sensitive are avoided. It is also important to take the tests done in previous years, so that the radiologist can compare if the breast has undergone any variation.

What is a breast ultrasound?

Breast ultrasound is a test that examines the breast using ultrasound. The doctor can see the image of the patient's breasts through a small device called a transducer. By itself, this test is not usually sent as a test for cancer detection, but as a complement. However, in women with dense breasts, with less adipose tissue, the inclusion of an ultrasound in the protocol improves the detection of this disease.

It is a painless test that does not need any preparation, although it is usually recommended not to use any moisturizing lotion in the area or deodorant. This test is very effective in finding small tumors that have not yet spread to the lymph nodes. It distinguishes between a solid mass and a cyst and helps find a tumor when the nipple produces transparent or bloody secretions. It is also a method that is used in the case of being necessary to perform a breast biopsy, functioning as a guide.

Various Tests to Detect Lung Cancer

X-ray exam is used to determine if there are lung nodules. Then you have to determine if they are malignant.

The computed tomography of the thorax (CT scan chest cost in Delhi) is a method of imaging by X-rays, which is commonly used for the diagnosis of lung diseases and is the only proven to reduce the number of deaths per test lung cancer, associated with early detection of the disease. The chest CT is indicated in all patients in which a pulmonary pathology is being studied. In recent years, it has also been shown to be effective as a screening method in lung cancer, similar to mammography for breast cancer screening.

It is not an annoying examination and practically does not have risks, except those related to the minimum radiation exposure. The CT, basically takes many pictures of the inside of the body using x-rays, allows to examine in a few minutes the entire thoracic cavity, so, including the necessary preparation, takes between 15 and 30 minutes.

According to the specialist, it is recommended as a lung cancer screening to perform a normal initial chest CT scan and subsequently a low-contrast, no-dose chest CT scan in the follow-up studies.

Tests and studies to detect lung cancer

If your doctor thinks you might have lung cancer based on the results of a screening test or because of the symptoms you have, other tests and tests will be done to confirm the suspicion.

Medical history and physical examination

Your doctor will ask about your medical history to learn more about any symptoms you have and possible risk factors. You will also be tested for signs of lung cancer or other health problems.

If the results of the history and physical examination suggest that you may have lung cancer, more tests will be done.

Tests to detect lung cancer

Sputum cytology

For this test, a sample of mucus that coughs from the lungs (sputum) is examined under a microscope to determine if it contains cancer cells. The best way to do sputum cytology is to obtain the samples early in the morning for three consecutive days.

Chest x-ray

If you have symptoms that can cause lung cancer, the chest x-ray will often be the first study that the doctor will order. Simple chest x-rays can be done in imaging centers, hospitals, and even in some doctors' offices. If something looks suspicious, your doctor may order other tests.

Computed tomography

A CT (CT scan chest cost in Delhi) uses X- rays to produce detailed cross- sectional images of the body. Instead of taking a picture, like conventional radiography, CT scans take many pictures while a device rotates around you while you lie on a stretcher. Then, a computer combines these photographs to form cross sectional images of the part of the body being studied.

Lung tumors are more likely to be detected on computed tomography (CT) than on conventional chest radiographs. CT scans can also show the size, shape, and position of any tumor in the lung, and can help find enlarged lymph nodes that may contain cancer that has spread from the lung.
