Images of the body: Ultrasound, ct, and MRI are three different types of imaging procedures which allow the radiologist see what's going on in your body. Each modality has it's own strengths, weaknesses, and indications. The best use of each is guided by the radiologist. The radiologist interprets at the images and provides a report to your doctor.

More info: Each imaging modality can be optimized to help learn more about diseases and help answer questions your for your doctor and you. For example, ultrasound is good at looking at the gallbladder; ct can show bleeding in the brain; MRI can show an acute stroke or find masses in the liver.

A 19-year-old female asked:

What can an MRI show that a CT can't?

It depends: Both are very good at imaging various parts of the body. Depending on the body part and the question being asked, ct or MRI may be better. In general, MRI can "see" the soft tissues a little better (e.g., brain and spinal cord, rotator cuff) and ct is sometimes better for looking at the bones (e.g., facial fractures, sinuses). Doctors work closely with radiologists to determine the best test.

MRI is totally different but in the proper hands can show many things that a CT can't. Early stroke, enhancement is more sensitive on MRI, prostate and pelvic imaging is improved. In the uterus the MRI shows the junctional anatomy better. In the joints it shows the ligaments and meniscus and cartilage better. In the shoulder it shows the rotator cuff better. In the brain it shows demyelination and hemorrhage much better. It is better at vascular lesions. Lesions of the spinal cord and disc herniations are easier to see. In general you need to ask your doctor which test might be better but in the brain MRI is almost always better.
