The Role Of MRI In Prostate Care

The clinical experience of using MRI for a non-invasive examination of the prostate gland and its surrounding structures can be calculated since the 1980s. Today, magnetic resonance imaging (MRI) of the prostate is one of the most informative and, at the same time, safe diagnostic procedures.

The priority and aspects of the techniques have changed and were associated with an analysis of the experience of using MRI. Clinical ideas about prostate cancer, methods and indications for various approaches to treatment have also changed.

MRI (magnetic resonance imaging) is the most effective study to determine the local spread of prostate cancer. Over the last decade the technology of MRI have improved significantly and allow us to have a dynamic contrast MRI, diffusion MRI, and MR spectroscopy in MRI scan centres in Noida. These technologies of MRI research are proven to be considered the best diagnostic imaging methods for prostate cancer. An MRI scan is especially effective when the lesion is located in the peripheral area of ​​the prostate gland.

Magnetic resonance imaging (MRI) of the prostate is attracting growing interest in the medical community. It occupies an increasingly important place in the screening, diagnosis, and treatment of prostate cancer. The risk of developing prostate cancer increases rapidly after age 50. Often this cancer can be asymptomatic in its early stages. It can demonstrate a variable evolution, such as being very slowly evolving without affecting the quality of life of a man or being more aggressive, requiring rapid management.

MRI is a major advance in the prostate investigation since it can generally identify precisely suspicious lesions as well as reassure other patients about the absence of clinically significant cancer and simplify their follow-up.

During an ultrasound, high-frequency sound waves are used to produce images of body structures. During a transrectal ultrasound (RTE), an ultrasound probe is inserted into the rectum to produce images of the prostate. It is used to:

  • Guide the needle used to take a tissue sample during a biopsy
  • Measure prostate size
  • Check for abnormal regions in the prostate

The doctors use several types of MRI tests showing various details of the images produced. Conventional MRI can detect a tumor in the prostate, but multiparametric MRI provides more details on its exact location, its aggressiveness and its spread outside the prostate. Multiparametric MRI helps the MRI scan centre in east Delhi to get better target on an abnormal region at the time of having a prostate biopsy. It also helps them in determining whichperson having prostate cancer needs to be treated immediately and who should benefit from active surveillance.

The MRI endorectal coil employs a thin rod having a small inflatable balloon around it and then inserted into the rectum. The help of thiskind of MRI is taken to get better images of the prostate than conventional MRI. If you have an MRI with an endorectal antenna, you patient will be given a light sedative or a relaxant to make the body more comfortable.

MRI Of The Brain (Magnetic Resonance Imaging)

MRI is a modern study of brain structures by recording an RF signal when a patient is placed in a device with a high magnetic field, which allows doctors to conduct a high-quality diagnosis of brain diseases/ injuries. Unlike other methods of radiation diagnostics, such as computed tomography, radiography, during MRI we get more diagnostic information, the accuracy of which is now the highest among all methods of radiation diagnostics of brain structures. In addition, with an MRI of the brain, the patient is not exposed to ionizing radiation; therefore, this procedure is safer for health than other diagnostic methods.


Diseases of the vascular system of the brain. In most cases, patients are referred for MRI test in east Delhi if the person has suffered a stroke or if there has been a hemorrhage in the brain. In this case, you can accurately see the affected area and understand how severe the hemorrhage was in order to use certain drugs to improve the patient's condition.

Endured various head injuries, especially those accompanied by neurological disorders, such as malfunctioning of the senses.

Oncological processes of the brain (primary tumors, secondary changes - metastases). In this case, MRI allows you to monitor the situation and see how much the tumor has increased or decreased after treatment.

Infectious diseases that occur with damage to the nervous system, such as meningitis, encephalitis, brain abscess, which, if improperly treated or absent, can lead to death.

Congenital anomalies of the substance of the brain for a long time may not produce significant symptoms, but under certain conditions (increased blood pressure, trauma, etc.), cause complications ending in temporary disability or disability.

Epilepsy, a condition accompanied by a malfunction of the cerebral cortex, in this situation it is necessary to see which part of the brain is damaged and what is its general condition.

Where to do an MRI of the brain

MRI- the gold standard for brain research, is the most accurate, safe and informative method of radiation diagnostics, both for assessing the anatomical structure of the brain and for visualizing pathological changes in its structure, and some specific studies can evaluate brain metabolism, but at the same time it requires the availability of modern expensive equipment in a medical institution, as well as highly qualified specialists who can make the correct diagnosis h based on studies.

Brain MRI is a painless procedure, as a result of which, using the influence of a magnetic field, and layered, detailed images of brain structures are obtained. MRI is a safe method of examination, i.e., when scanning, X-ray (ionizing) radiation is not used, and the patient is not "irradiated" during the procedure, as a result of several examinations it is possible to go through at a time. It is good to know the MRI test cost in Noida before undergoing the treatment.

If necessary, MRI of the brain is performed with contrast. A contrast agent is used to study processes in the organ or tissue under study in more detail. When injected into a vein, the blood flow brings a contrast medium to the zone of interest, after which a targeted study of this zone is performed, this allows you to identify and confirm the presence, as well as evaluate the dynamics of oncological and inflammatory processes in the brain.

Why Is MRI Scan So Noisy?

Magnetic resonance imaging (MRI) has become in recent years one of the most requested tests within a diagnostic imaging service thanks to its great potential to differentiate the different tissues that make up the human body, but why is it so noisy. It is the question that many patients ask themselves at the end of the test.

The Magnetic Resonance imaging machine is basically composed of a powerful magnet, mostly superconductors, with a transmitter and a radio wave receiver, in addition to all the electronics needed to coordinate its operation. The magnet creates a powerful magnetic field even more powerful than that of the earth, the transmitter, in turn, emits radio waves that are directed towards the patient, these waves excite the protons of the different tissues and the receiver picks up the emitted signal with which will create the image.

There are four magnets, one main, the largest and most powerful, and the other three smaller ones are the gradients, which are inside a large metal coil called the gradient coil. This coil is composed of copper electromagnets that create a secondary magnetic field in each of the three directions of space and fulfill a fundamental function since they are responsible for spatially locating the Magnetic Resonance signal and encoding it to create the image that is performed by MRI scan centre in East Delhi.

Why so much acoustic noise? To generate the magnetic field an electric current has to be applied and when it is applied in the presence of a static magnetic field they produce variable magnetic forces that act on the gradient coil (mechanical vibration) and causes it to expand and contract rapidly in a matter of milliseconds producing movements or vibrations generating the noise that is manifested throughout the room, so we can say that the main reason the noise generated by the RM machine present in the MRI test labs in Delhi are the gradient coils.

There are other factors that contribute to generate noise such as the modification of acquisition parameters, acoustic noise tends to improve with the decrease of the thickness of cut, the field of vision (FOV), TR (repetition time) and TE ( echo time) but this may affect the resulting image.

On the other hand, the characteristics of the acoustic noise have a spatial dependence depending on the position and the size of the patient the levels can vary in about 10dB.

Studies conducted including a variety of pulse sequences where several gradients are applied resulted in this type of sequence (3D and GR) being among the strongest with levels ranging from 103 - 113 dB. Other studies also measured the acoustic noise generated by the echo-planar (EPI) and the FSE (fast spin-echo) sequences in 1.5T, noise levels ranging from 114 to 115 dB and at 3T levels in the range of 126 to 131 dB for these noise levels the use of hearing protection is recommended.

General Electric GE developed a technology called Silent Scan a few years ago that allows to reduce acoustic noise to a level similar to that of ambient sound, if we take into account that an RM scanner without this technology generates a noise of approximately 100 dB, depending on several factors, this decrease of almost 30 dB causes greater patient satisfaction and generates a more pleasant silent and comfortable experience.

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.
