Getting a Better Understanding of the MRI Procedure and its Functions

Magnetic resonance imaging, known as an MRI, is a procedure that uses pulses of radio waves allowing physicians to take pictures of structures and organs in a patient’s body. Magnetic resonance imaging offers a closer look at a patient’s body that is not visible through other imaging technologies, such as X-rays.

Several types of machines exist for patients who need magnetic resonance imaging tests. The newest technology is the 3T test offering the most powerful imaging in health care. The 3T machine creates a much stronger signal strength than 1.5T machines providing physicians with clear and vivid images.

The parts of the body physicians can view using a magnetic resonance imaging test include bones and joints, the head and brain, the heart and chest, the pelvis and the stomach. Doctors can search for signs of tumors, kidney or liver problems and prostate cancer to name a few conditions.

Magnetic resonance imaging test can detect torn ligaments around joints, and the test can identify a narrowing of the spinal canal or a herniated disk. For women, a magnetic resonance imaging test identifies problems with the uterus or ovaries. The image also helps doctors identify any birth defects in a patient’s heart. The imaging also identifies serious issues such as signs of a stroke or internal bleeding in the brain.

Although most medical technology does not deliver accurate results 100 percent of the time, most experts do agree that magnetic resonance imaging tests deliver accurate results the majority of the time. Powerful, new technology allows doctors to view organs and body structures with clear and vivid images. However, the accuracy of any test, no matter how powerful, is only as good as the person viewing the results. False negatives often occur when doctors report incorrect unfavorable conditions.
