CT Guided Biopsy

A biopsy is a test in which a Radiologist (x-ray doctor) collects tissue samples, which will be looked at under a microscope by a lab doctor, called a Pathologist.

A biopsy is done to determine whether an uncertain area/mass is benign (negative) or malignant (positive).

CT Scan images will allow the doctor to guide a needle into the questionable area. Tissue samples will be removed and sent to the lab for testing.
A nurse will be monitoring you and giving you sedation, if needed, during the procedure.

Procedure time: 60 - 90 minutes

Patient Preparation Instructions:

  1. Nothing to eat or drink 6 hours before your test.
  2. You may need to have blood work drawn before your procedure. Radiology will call you prior to your exam. Outpatient registration will have a copy of your lab work order, if needed.
