Myths and Realities: Magnetic Resonance and CT Scan are They the Same?

They are not. Having a CT (Scanner / CT) or Magnetic Resonance (MRI)  have in common that they are medical tests performed by the Technicians in Radio diagnosis (TSID) and that they provide images of the inside of your body. However, they fulfill this vital task in very different ways:

RADIATION

The CT scan uses ionizing radiation (X-rays) to produce the images, while Magnetic Resonance does not use ionizing radiation.

FUNCTIONING

A CT scan is an X-ray tube moving around the stretcher where the patient is lying down, and as this movement is made, multiple images (x-rays) of the body are obtained using X-rays from different angles. An MRI uses radio waves and powerful magnets to obtain the images, and although the stretcher can be moved, generally during the test the patient and the stretcher do not move. Different sequences are applied, and images are obtained once these are finished.

DIMENSIONS-CLAUSTROPHOBIA

The CT scan is in the form of a "donut," and during the test, the space between the patient and the team is wider than during an MRI. The MRI is a more or less elongated cylinder, but less "comfortable" than a CT scan. It is because of this design and its dimensions that if you are a person that you usually have claustrophobia or you are prone to overwhelm yourself in closed places, it is more likely that it can happen during an MRI than when performing a CT scan.

If this is the case, you should let the Radio-diagnostic Technician know that you will be tested so that he can inform you directly, show you the equipment and accompany you with his voice and vigilance during the development of the test.

UTILITY

The TAC is handy to evaluate bone injuries and internal injuries technique while the MRI is used to assess exceptionally soft tissue of the patient. The radiologist (a doctor specialized in radio diagnosis), evaluates according to the type of injury if it is convenient to perform one or another technique and even both.

METALLIC OBJECTS IN THE ROOM

In RM rooms it is not allowed to enter with metallic objectives (implanted or external) as they can cause problems in the study and safety. However, in the CT SCAN room, and just like when they perform a simple x-ray, it is allowed to enter the room with metallic objectives, but they should not be in the study area.

WEATHER

The time to perform a CT scan at a CT scan centre is much less than the time needed to perform a Magnetic Resonance Imaging. The TAC is a faster test to perform than an MRI, so in an emergency, it is usually the indicated test for a first diagnosis.

NOISE

The CT SCAN is a silent test if we compare it with an MRI study, in the CT SCAN you will hear the sound of the Rx equipment spinning around you while in the MRI it is a little more uncomfortable sound but more bearable if we reduce it with plugs or helmets compatible.

What Imaging Tests to Use to Detect Brain Aneurysms?

To go into deepness on this subject, it is essential that we know what a cerebral aneurysm is and, from there we will discover what the symptoms and causes are and finally understand how to detect it and what clinical tests to be performedby MRI test labs in Delhi, we begin!

A cerebral aneurysm is a cerebrovascular disease in which an abnormal widening occurs in the wall of a brain artery.

What is a cerebral aneurysm?  

A cerebral aneurysm is a cerebrovascular disease in which an abnormal widening occurs in the wall of an artery of the brain, which swells with the passage of time. This is due to a weakening of the wall of this, which makes the pressure of the blood to tighten it, even more, increasing the risk of the vessel ruptures and a part of the brain is filled with blood.

Symptoms of a cerebral aneurysm:

Signs may exist before the rupture of the blood vessel and signs after rupture. In the first case, the symptoms that can occur are a headache, dizziness, alterations in perception, loss of vision and balance. And the signs of a ruptured aneurysm are a stiff neck, pain in the face, double vision, sensitivity to light, seizure or change in speech or mental acuity, among others.

What causes brain aneurysms?

First of all, it is good to know that brain aneurysms can occur due to genetics or acquired diseases, as well as the consequence of unhealthy lifestyle habits such as alcohol consumption, tobacco abuse, excessive intake of foods with high levels of fats and sugars, drug use like cocaine or also due to the use of certain contraceptives and anticoagulants.

Imaging tests for the detection of a cerebral aneurysm:

The aneurysms can be diagnosed through several imaging tests, such as Computed Tomography (CT), brain magnetic resonance angiography (MRA) and computed tomography angiography of the head (CTA), which we explain below:

Computed tomography (CT)

This type of imaging test is usually the first user to determine if there is bleeding in the brain. If you want to deepen and better observe the blood flow, an angiography by computerized tomography will be performed, explained below.

Computed Tomography Angiography (CTA)

In this test, the patient is inserted with a dye that allows the professional to observe better the flow of blood in the brain and X-rays show a 3D image of the blood vessels and surrounding brain tissue, which could indicate more safely the presence of an aneurysm in the brain.

Magnetic Resonance Angiography (MRA)

MRA, which does not emit X-rays, is used to evaluate blood flow through the network of blood vessels in the brain. During this test, a dye can be injected to show the blood vessels more clearly.

The Differences between Making a Conventional CT Scan and One of the Latest Generation

The new computed tomography devices are not only less harmful to patients, but also facilitate and speed up the diagnosis process notably.

The doctor advised me that he has to perform a CT scan and that he will do it with a new generation computerized tomography equipment. What advantages do you have compared to the conventional CT?

The main advantage is that images is lower dose of radiation to the patient and lowest cost CT scan in Delhi. Also, its higher resolution power makes it possible to identify lesions with greater clarity and, being more quickly, the problems caused by the involuntary movement of the patient are reduced.

This new technology also allows heart studies to be made in the time that a heartbeat lasts, as well as screening for lung cancer using low radiation dose protocols. Finally, in the cases of patients who may have implanted metallic materials, it contains contracts that reduce the distortion of the image produced by these implants.

Does it involve any risk to undergo this test?

Only the inherent risk derived from radiation, although it is lower than in conventional CT since it has a precise dose control system that ensures the minimum radiation needed in each scan and for each patient (calculated about their physical characteristics). Also, it is a highly safe test in pediatric patients.

Do I require to do any prior preparation? Is the test always performed with contrast?

Most studies do not require any preparation on the part of the patient. Specific scans need fasting or certain restrictions in the diet. Some cardio logical examinations must be preceded by medication to control the heart rhythm, always under medical supervision. Neither is it still necessary to administer contrast, although in many cases its administration provides more information for diagnosis.

The conventional CT scan may take several minutes, depending on the body region and the size of the patient. CT is the technique of choice to acquire two-dimensional complete axial images of the body without the disadvantages of bone or air overlay of conventional radiographs.

One of the advantages of the helical technique by CT scan centres is the possibility of detecting lesions smaller than the conventional thickness of a cut.

Both in the CT with the single crown detector and in the multi-detector CT, the data is acquired continuously while advancing the table through the Gantry. The X-ray tube describes an approximately helical path around the patient. If the progress of the table is coordinated with the time required for a 360º rotation, the data acquisition will be complete without interruption.

In conventional CT the x-ray tube receives the energy for a rotation, which usually lasts 1sg and the intervals of 6 - 10 sg, this allows the tube to cool between one sweep and the next. In the helical CT, the x-ray tube is subjected to a crucial thermal state, since it receives energy for about 30 sg without interruption. Therefore, the helical CT tube is characterized by its high thermal capacity, its high cooling rates, and its large size. All these technical conditions increase the noise of the system.

The Ultimate Guide: An Overview on CT Scan

The sole reason as to why a doctor would order a CT Scan Abdomen or of the chest is to make detailed pictures and analyze the internal structure. CT scan is also known as Computerized tomography (CT) which is useful in obtaining very detailed 3D image of certain parts of the body.

The process is a progression of the x-ray project albeit one may deduce that it is done by taking many different x-ray views which are combined with the use of computer processing. They create cross-sectional images of the bones and soft tissue inside of the body, including tissues inside of solid organ. The reason why X-rays are not a very preferred choice of imaging is due to the fact that the rays do not show clear images of soft tissues. The CT scan also gives the flexibility to use a contrast dye that allows showing up clearer image on the screen.  A crystal clear CT scan displays all the structures of the body including the lungs and cancer tumor.

Reasons for a Chest CT scan: 

CT scans are used for a multitude of reasons. Its benefits particularly help in the checking for certain cancers, the development of abnormal tumors and growth of lumps if any.

The CT scans have the ability to successfully locate the tumor, the stage at which the cancer is at and where to perform a biopsy.  The CT scans such as those for the chest can also be ordered after a mammogram exam. Some CT scans are tailored to look for heart disease, aneurysms of the aorta or pulmonary emboli.

In the aftermath of a therapy or surgery, a CT is perhaps the first that gets prescribed in the CT scan centre. This gives a clear idea as to how well the body is responding to treatment.

CT scans can be used to detect cysts or infections in the body.

It is now more of a regulation to go for a CT scan to inspect any internal injury after an accident to identify grave injuries especially the internal ones.

Role of CT scan in diagnosing the problems of the chest

  •         A CT scan can help doctors diagnose the cause of shortness of breath or chest pain, as well as find the cause of abnormal findings from a standard X-ray.
  •         A CT scan of the chest can discover masses, tumors, infections, or injuries. It can also show excess fluid around the lungs or a blood clot in the lungs.
  •         The problems such as blocked blood vessels, cancer, injury or heart problems can be assessed with a CT scan.
  •         Chest scan, also known as thorax CT scan can look into the potential problems of the heart, lungs esophagus, the aorta or even the tissues of the chest.

 

What is the safety limit of CT scan?

It is true that the CT scan test in the CT scan center Delhiis administered with radiation exposure but there is almost a cent percent chance that they are unlikely to harm the body in any internal or apparent way.

The CT Scan Cost Delhi   is between INR 2000 and 4000. For the CT scan brain angiography, the scan centers may charge anywhere around INR 12000.

Brain Injuries In Child – What Precautions You Must Take

Brain injuries among children are very common because of their overactive nature. Children; especially the toddlers are more prone to get such kind of injuries while learning their first steps. They often fall and get their head bumped on the floor, walls or furniture and other nearby objects. These kinds of incidents may seem very familiar in every household that has toddlers. But in some cases, these injuries can be very dangerous for your child, and this is the prime reason you should not ignore them.

However, you cannot stop your child from being active or sometimes overactive. It is their instinct, and it is also good for their health. But you can be aware of the precautions that you should take whenever your child gets any sort of brain injury.

  • First, never ignore the injury no matter how small or unharmful it may seem initially. You should try to provide some first aid and call your pediatrician to inform about the incident. If he suggests you to take your child to him, then do so immediately. He may suggest you observe your child’s activities for the next 48 hours to be sure about the severity of the injury.
  • If your Doctor suggest you to go for a head CT Scan test, find out the head CT Scan cost in Delhi and take your child to the nearest CT scan center for immediate examination.  

Why Scan Is Important

CT scan is a process that gets you some clear and accurate images of your brain. These details images help the doctors to understand exactly which part of your child’s brain is affected due to that injury and how serious it is.

The doctor can then decide the further treatment plan for your child on the basis of the report of CT Scan. Fortunately, there are advanced technologies that can make it easier for the radiologists as well as the doctors to find out the damage and get the best treatment for your baby.

Similarly, the test can also help the doctors in future to follow the progress of the patient after applying for the medicines or doing surgery. They can check whether the patient is responding properly on that treatment procedure or not.

Is CT Scan Imaging Same as MRI?

Both MRI and CT are two of the significant advances in current medicine since they allow the examination and detection of diseases using non-invasive methods, without the use of pesky and aggressive techniques such as lumbar punctures or arthrography for the patients.

For both reviews, the patient should lie on a stretcher and enter a relatively narrow cylindrical tunnel. The difference is that in MRI test the tube is a large electromagnetic magnet that allows you to take pictures of the inside of the body by subjecting it to a magnetic field. In a CT, the images are taken using an X-ray beam that makes a circular movement that surrounds the area to be investigated (multiple X-rays from various angles).

With the CT tests, it is possible to reconstruct in three dimensions the area explored, which is very useful when planning a surgery and is the order of the day to locate and treat tumors. Both are image tests, but they are not the same. The CT Scan cost is highly dependent on the scan center and clinic you are going for!

Magnetic resonance uses powerful magnetic fields to produce and detect changes at the molecular level of substances like the hydrogen that contains our body. These changes are very subtle and disappear when we leave the machine, but the machine can detect them and translate them into images of the interior of the body.

Both CT and resonance allow us to explore the inside of the body, but each one is more sensitive to a particular type of injury, so your doctor will indicate the one that is most appropriate as the case may be.

What is a CT Scan Test? What Does it Consist of?

The CT scan test is performed with a device called a scanner. During this test, the body is subjected to multiple rays released simultaneously from different angles, and then a computer assembles them to generate an image of the area to be studied. CT scanning is more detailed than an x-ray since only a beam of light is used on the current x-ray.

Because CT scan is a non-invasive procedure that provides detailed cross-sectional views of all tissue types, it is becoming the ideal method to diagnose many intestinal diseases such as diverticulitis and appendicitis and to visualize the liver, spleen, pancreas and the kidneys.

And Magnetic Resonance- What Does it Consist of?

On the other hand, Magnetic Resonance is a machine that allows obtaining an image of the soft tissues of a patient using the use of a magnetic field. Powerful magnets and radio waves are used to create body images. The main difference between CT and MRI test is that the second one does not use X-rays. Other differences are that the CT scan is faster to perform but has a lower resolution.

Because MRI test can give such clear images of the soft tissues around the bones, it is the most appropriate examination for spine and joint problems. It is also widely used to diagnose sports injuries, especially in the knee, shoulder, hip, elbow, and wrist. The images allow the doctor to see even tiny tears and lesions in the ligaments and muscles.
