A CT pelvis with contrast is typically requested by a healthcare provider when there is a suspicion of a problem in the pelvic area that needs further evaluation. This may include symptoms such as abdominal or pelvic pain, unexplained weight loss, abnormalities found during a physical exam, or suspected tumors or cancer.The test involves lying still on a table while a CT scanner takes images of the pelvic area. Prior to the test, patients will receive an injection of contrast dye, which helps to highlight blood vessels, organs, and other structures in the pelvic area.
