The MRI reads the energy from the water molecules and builds a 3-D image of the different types of tissue. This energy is directed at water molecules in the body, "exciting" and then "relaxing" the protons in water molecules. Lying inside a large, hollow magnet, you will be exposed to radio waves. This table will slide into a large tunnel-like tube in the scanner, and you will be told to breathe quietly and normally but to stay very still. Your head will be placed in a padded plastic cradle or on a pillow. You will be asked to lie on a narrow table. This test is done in a hospital radiology department or in a health care provider’s office by a technician, supervised by a doctor. Based on 3-D MRI images, a urologist or radiologist can see if a mass is cancerous or benign (not cancerous). It can show clear 3-D images of its shape. It can clearly show blood vessels and lymph nodes.įor example, if a mass is found in the kidney, MRI can tell the difference between a hollow cystic mass and a solid mass.
It can spot masses and cystic structures. It can show soft tissues in great detail. MRI can be tailored to help answer almost any clinical question. This can help to more accurately make a diagnosis. With MRI, certain settings will show different types of tissue.
This is good if you have kidney problems.
