Magnetic Resonance Imaging, or MRI, and Computerized Tomography, or CT scans, are tests that use computers to create three-dimensional or cross-sectional images of internal organs. These tests can help identify abnormal structures, although they cannot differentiate between malignant tumors and benign prostate enlargement.
In an MRI, a magnet, radio waves, and a computer are used to make a series of detailed images of areas inside the body. In a CT scan the images are made by a computer linked to an X-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly.
If a biopsy has confirmed the presence of cancer, your provider may recommend an MRI or CT scan to determine if the cancer has spread.
