Everyday blooming and healing medical world bring many techniques to learn about your any and every health ailments. The numerous tests are readily available and one of the most accurate and prominent tests is MRI.
Magnetic Resonance Imagining (MRI) is a test that utilizes potential magnets, radio waves and PC to take thorough pictures of inside body. This test does not utilize x-ray radiations. It can be read by the specially trained doctor called a radiologist though it is explained to us by our concerned doctor pursuant to the reports prepared by the radiologist.
Physicians use this test for two reasons; to diagnose a disease or injury and if under treatment then how well your body is responding to the treatment. MRI is done to almost every part of our body such as brain, heart, spinal cord, blood vessels, bones and joints, breasts, liver, kidneys, ovaries (women), pancreas, prostate (men) and a special kind of MRI is done to render brain activity called a functional MRI (fMRI).
fMRI examines the blood flow in your brain to investigate areas active when you do a certain task. It assists to discover brain issues such as stroke, epilepsy or tumors to plan your treatment.
What it diagnoses?
An MRI scan can be used as an extremely accurate method of disease detection throughout the body and is most often used after the other testing fails to provide sufficient information to confirm a patient’s diagnosis.
MRI is a milestone in the medical world since it is used to get an accurate and detailed picture of inside the body. Here are some major examples were unfeasible to examine before MRI;
- Diseases of the liver and other abdominal organs
- Injuries or abnormalities of the joints
- Abnormalities of the brain and spinal cord
- Tumors or epilepsy, cyst, and other deformities in any part of the body
- Specific types of heart problems such as congenital heart disease
- Causes of pelvic pain in women
- Liver and other abdominal problems such as Cirrhosis, bile duct or pancreas disease
- Bone infections, etc
An MRI scan is a painless radiology technique that has the advantage of avoiding any radiation exposure. There are no known side effects of an MRI scan as such. The benefits of an MRI scan relate to its precise accuracy in detecting structural abnormalities of the body.
MRI is a noninvasive alternative to X-ray, angiography, and CT to examine problems of heart and blood vessels. It is difficult to differentiate between cancer tissue and edema in MRI and it is bit costly are the only limitations many researchers discovered yet.
