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 him 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.
- In most cases, you will arrive 90 minutes prior to your scheduled procedure for preparation with a prescription if your doctor has given one to you.
- Have nothing by mouth after the midnight prior to your exam.
- Blood work is required prior to most guided procedures.
- If you are taking any blood thinners (Coumadin, Aspirin, Ibuprofen, Motrin, Lovenox, Plavix)) including aspirin or Motrin products (NSAID’s), they will have to be stopped 5 days prior to the procedure, with your doctor’s consent.
- A nurse will obtain vital signs during the procedure.
- A nurse will call you to obtain health history, complete the scheduling process, and answer questions.
- A radiologist will interview you for health information
- Depending on the procedure, your total stay may be as short as 2 hours or as long as 8.
