What is this test?
A CT-guided abdominal biopsy is a minimally invasive procedure in which a needle is directed into a suspicious area in the abdomen using CT scans for guidance. A small tissue sample is removed for examination by a pathologist.
Why might I need this test?
This test may be recommended to evaluate an abdominal mass, enlarged organ, cyst, or other abnormal finding found on imaging. It can help determine whether suspicious tissue is cancerous or identify another cause for the abnormality.
How is the test performed?
You will lie on a CT scanner while the clinician identifies the target area with images. After numbing the skin, the needle is inserted, usually with continuous CT guidance, and several small tissue samples are collected. The samples are then sent to a laboratory for microscopic and other testing.
How do I prepare for the test?
Follow the instructions from your healthcare facility, which may include blood testing, review of medications, fasting, or arranging transportation if sedation is used. Tell the clinician about blood thinners, diabetes medicines, allergies, pregnancy possibility, and any prior reaction to anesthetic medication.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The biopsy may show normal tissue, inflammation, infection, a benign growth, or cancerous cells. Results are interpreted together with your symptoms, imaging findings, prior tests, and the pathologist's observations. Additional testing may be needed if the sample is too small or the results do not explain the imaging findings.
