Because MRI can give such clear pictures of soft-tissue structures near and around bones, it is the most sensitive exam for spinal and joint problems. The images allow the physician to see even very small tears and injuries to ligaments and muscles.

 

With MRI, physicians can examine the size and thickness of the chambers of the heart and determine the extent of damage caused by a heart attack or progressive heart disease. Organs of the chest and abdomen can also be examined in high detail with MRI, enabling the diagnosis and evaluation of tumors and functional disorders.

 

An MRI Scan

MRI is a safe, painless technique used to view an area inside your body. It lets doctors view tissues inside your body without using surgery or X-rays. During an MRI exam, the MRI equipment surrounds your body with a harmless magnetic field. The scanner sends radio signals through the part of your body being scanned, and your body tissues send a signal back, helping to create an image.

 

These computer-processed images help your doctor pinpoint and diagnose problems early so effective treatment can be given when necessary. Unlike X-rays and CT scans, MRI does not use radiation.


MRI produces high-resolution images that are used to evaluate many areas of the body, including:

  • brain
  • spine
  • bones
  • joints
  • blood flow

 

Benefits of MRI

  • Images of the soft-tissue structures of the body—such as the heart, lungs, liver and other organs—are clearer and more detailed than with other imaging methods.
  • MRI can help physicians evaluate the function as well as the structure of many organs.
  • The detail makes MRI an invaluable tool in early diagnosis and evaluation of tumors.
  • MRI contrast material is less likely to produce an allergic reaction than the iodine-based materials used for conventional x-rays and CT scanning.
  • MRI enables the detection of abnormalities that might be obscured by bone with other imaging methods.
  • MRI provides a fast, noninvasive alternative to x-ray angiography for diagnosing problems of the heart and cardiovascular system.
  • Exposure to radiation is avoided.

Risks of MRI

  • Every year approximately 10 million patients undergo MRI procedures. In general, the MRI procedure produces no pain and causes no short or long-term damage of any kind. The fact that there is no radiation exposure also decreases the risk of having an MRI.
