CT or Ultrasound Guided Biopsy and Drainage Procedures
Please note: This is an Interventional Radiology procedure. A specially trained doctor called an Interventional Radiologist will use a CT machine or an Ultrasound to guide to a specific target. Typically, the target is a collection of fluid to be drained or an area of concern within the body that must be biopsied for further study. Generally, prior scans, ultrasounds or x-rays of affected areas will need to be viewed by the doctor before scheduling of these procedures can be completed.
- Depending upon the area of concern, you may be required to lie on your side, your back or your stomach.
- A CT or Ultrasound is used to scan the area of concern.
- The skin over the site is cleaned. A local anesthetic is applied to numb the skin.
- The site is accessed with a straight needle. Biopsies are taken as necessary. In some cases a thin tube is exchanged with the needle to drain a collection of fluid.
