ACR - MRI snaps clear, detailed pictures

ACR - MRI snaps clear, detailed pictures: "What is an MRI?
Magnetic resonance imaging uses radio frequency waves and a strong magnetic field, rather than x-rays, to provide clear, detailed pictures of internal organs and tissues.
What are some common MRI uses?
Because an MRI procedure can give such clear pictures of soft tissue structures near and around bones, it is the most sensitive examination for spinal and joint problems.
MRI is used to diagnose sports-related injuries, especially those affecting the knee, shoulder, hip, elbow and wrist. The images allow doctors to see even very small tears and injuries to ligaments and muscles.
Organs of the chest and abdomen, including lungs, liver, kidney, spleen, pancreas and abdominal vessels can be examined in high detail with MRI, enabling diagnosis and evaluation of tumors and functional disorders.
What do patients experience during an MRI procedure?
MRI causes no pain, but some patients can find it uncomfortable to remain still during the examination. Some experience a sense of being closed in, though the more open construction of newer MRI systems, including the one at Markham Stouffville Hospital, has done much to reduce this reaction
If a contrast injection is needed, there may be discomfort at the injection site, and patients may have a cool sensation at the site during the injection. Most bothersome to many patients are the loud tapping or knocking noises heard at certain phases of imaging. Ear plugs may help.
Who interprets the results and how do patients obtain them?
A radiologist, who is a physician experienced in MRI and other radiology examinations, analyses images and sends a signed report with his or her interpretation to the patient''s personal physician. The patient receives MRI results from the referring physician "
