CT-Guided Pelvic Biopsy with Intravenous Contrast

What is this test?

A CT-guided pelvic biopsy is a minimally invasive procedure in which CT imaging helps guide a needle to a suspicious area in the pelvis. A small sample of tissue or cells is removed for examination by a pathologist. Intravenous contrast may be given before the procedure to improve the clarity of the images.

Why might I need this test?

This test may be recommended when an imaging study shows a pelvic mass, lesion, or abnormal tissue that cannot be identified clearly without a biopsy. It can help evaluate whether the area is cancerous or may represent another condition, such as inflammation or infection.

How is the test performed?

You will usually lie on a CT scanner table while a radiologist identifies the target area and guides a biopsy needle into it. Local anesthetic is commonly used, and sedation may be offered depending on the procedure and your condition. The area is then checked with images to confirm that the needle is positioned safely and that bleeding has stopped.

How do I prepare for the test?

Follow the facility's instructions about fasting, medications, and arrival time. Tell the care team about any prior reaction to CT contrast, kidney disease, pregnancy or possible pregnancy, bleeding disorders, and medicines that increase bleeding risk. Do not stop prescription or blood-thinning medicines unless your clinician specifically instructs you to do so.
