MRI Scans in Bangalore

What is an MRI Scan?

Magnetic Resonance Imaging (MRI) is a medical imaging technique which requires no incision. It depends on strong magnets and radio frequency waves to provide a high-quality picture of the structures inside the body.

It is a machine with a tunnel and the patient is pushed through this and the machine takes images behind images cutting through the tissue depths of an organ. This enables precise identification of abnormal tissues and organs.

MRI makes it a lot safer for repeated use as compared to X-ray or CT X-ray as the former does not involve ionising radiation which in turn solves a lot of issues. It is particularly good for imaging soft tissues, the brain, chords the spinal muscles and joints.

MRI is considered as one of the safest methods of imaging as it does not involve the use of ionised radiation, however, it has its risks too, here are some of them: -

• One of the main disadvantages of MRI scans is that it is not appropriate for people with some types of implants or metal in their body, such as pacemakers.
• MRI might have some difficulties in obtaining images in the parts of the body that are prone to movements like the intestines.
• Patients that are claustrophobic may not feel at ease as the MGMRI is quite enclosed.

It is required to understand that the parameters vary based on the type of MRI scan and the objectives of performing the scan. Nevertheless, there are several common parameters and indicators which radiologists watch during an MRI scan: -

Tissue Characteristics

T1 Weighting: it is valuable in assessment of 3D anatomy of very specific tissues, and, for example, this weight increases the relative signal of fatty tissues content of those tissues.

T2 Weighting: These are useful in addressing healthcare professional’s concerns relative to the presence of oedema, inflammation and other types of tumours.

It concerns identifying the amount of water within biological tissues.

Proton Density (PD) Weighting: PD assesses the number of hydrogen protons within a tissue which assists in characterizing and detecting various tissue items.

Tissue Integrity

Morphology: This concerns normal and abnormal organ and tissue shape, size, and positioning.

Signal Intensity: Cases of tumours, bleeding, inflammation and so on can be seen due to the shine of the tissues on the image

Texture: The condition of the tissues which may be smooth, rough or heterogeneous etc would be visualized.

Your doctor might suggest an MRI for several reasons, some of them being: -

Tumour Detection: MRI scans allow doctors to see details of certain abnormalities such as tumors enabling them to detect it with ease.

Assessing joints and the Musculoskeletal system injuries: Considering musculoskeletal problems, the most effective way of examining them is by using MRI which provides clearer images of joint and muscle injuries.

Liver and Kidney Cancers: An MRI evaluation assist doctors to determine the kind of ailment that is present on the liver and kidney as in cirrhosis or fatty liver disease, etc or kidney cysts or tumors.

Cardiac An MRI heart provides adequate images of heart structure and its functions which medicate the diagnosis of cardiomyopathy congenital heart disease, heart valve diseases and even heart conditions in general.

MRI scans come with multiple advantages, and because of its versatility, it is considered one of the best imaging tools that can diagnose a wide variety of conditions. Here are a few of the advantages of MRI scans.

• MRI is painless and non-invasive, there is no requirement for incision therefore it is possible to do a thorough examination without any invasive procedures.
• Exposure to ionizing radiation is not possible during MRI since it uses magnetic fields instead making it a safer option for patients who require multiple scans
• MRI also utilizes very high-resolution scans, it provides sharp and clear images of soft tissues, which greatly assists in intricate diagnosis securing imaging procedures.

MRI is a multi-dimensional imaging technique that assists healthcare professionals in diagnosing a range of conditions, including but not limited to:

• Conditions such as brain cancer, stroke, and multiple sclerosis
• Spinal cord damage, herniated discs, and nerve injuries
• Liver and heart diseases and tumorous growths on the kidney
• Ligament and bone related injuries including fractures and sprains
• Vascular conditions such as blocked arteries or aneurysms

MRI scan procedures differ depending on the condition of the patient which in turn dictates how different kinds of MRI scans are done.

Nonetheless, here are some general rules that will potentially enable you to be better prepared for the scan.

Requirements

In the case of MRI such as the abdomen MRI, your physician would like to know if you have kidney problems, allergies as well as would like you to fast and if you have any metallic devices or implants, it is advisable to inform the doctor. Additionally, patients must take off necklaces, bracelets, watches, and any metal accessories like clips in hair prior to the MRI.

Ideal Time for MRI Scan

The ideal time for an MRI scan differs from one patient to the other and it also depends upon practical conditions as well as the type of scan one goes for. For instance, some are recommended to stay away from food or drinks around the time of the abdominal scan. For them, the early hours of the day are optimal.

Qualifications

Most people are suited to undergo MRI however there are people who suffer from certain types of metallic implants or are claustrophobic and might not be able to use MRI. Closed MRIs may be used for patients who cannot tolerate being in tight places.

Getting Ready for An MRI

You will have to change into a hospital gown and lie on a table that goes into the MRI machine while your scan is being performed. You will have to protect your ears due to how loud the machine is.

The breath-hold command is often given by the technologist in order to avoid blurriness of the images.

Precaution malpractice Observation Before the Scan

Inform your doctor of such metal implants, as they can affect the scan and some MRIs use contrast dye, because it is necessary to let your physician know of any allergies or diseases.
