CT-Guided Pelvic Biopsy Without Contrast
A CT-guided pelvic biopsy samples suspicious tissue in the pelvis for examination under a microscope. No intravenous contrast is used for this version of the procedure.

What is this test?
A CT-guided pelvic biopsy is a minimally invasive procedure in which a needle is positioned under CT imaging and used to remove a small sample of tissue or fluid from the pelvis. The specimen is then examined in the laboratory to identify infection, inflammation, or abnormal cells.
Why might I need this test?
This procedure may be recommended when an imaging study shows a mass, lesion, fluid collection, or other unexplained abnormality in the pelvic area. Tissue analysis can help doctors narrow down the cause and guide treatment decisions.
How is the test performed?
You will usually lie on a procedure table while CT images show the clinician where to place the biopsy needle. Local anesthetic is commonly used to numb the area, and several small tissue samples may be collected. The samples are sent to a pathology laboratory for evaluation.
How do I prepare for the test?
Follow the specific instructions provided by the imaging center, especially any fasting or medication guidance. Tell the clinician about bleeding disorders, blood-thinning medicines, prior anesthesia reactions, and whether you are pregnant. Arrange transportation home if sedation will be given.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Biopsy results may identify benign conditions, infection, inflammation, or cancerous changes in the sampled pelvic tissue. If no abnormal cells are found, the clinician may consider other explanations or additional tissue sampling. Results should be interpreted with the imaging findings, symptoms, and other medical history.
