CT Guided Biopsy

What is a CT Guided Biopsy?biopsy

This is a procedure performed by a radiologist to obtain a small tissue sample through a needle. This is done to make a diagnosis and plan future management. CT scan is used to guide the needle into the lesion in the safest possible manner. This is a minimally invasive procedure and is an alternative to an open surgical biopsy. CT guidance generally results in fewer complications, a faster recovery time, and avoidance of general anesthesia.

How Does a Patient Prepare for a CT Guided Biopsy?

If you taking blood-thinning medication e.g. Coumadin, or you are taking anti-diabetic medication, e.g Glucophage (Metformin), please contact our clinic immediately at (352) 265-0875 or (352) 265-0116 to report either of these conditions.

If you are allergic to contrast, please call the above-mentioned numbers to report this condition.

You should have your last meal before midnight the day of the procedure. If you take blood pressure medication, please take it as scheduled with a sip of water.

What to Expect

Prior to your procedure, you will be prepared in the holding area where you will change into a hospital gown and an IV will be placed. Through the IV you may receive sedation and pain medications that will keep you relaxed and comfortable. You will be taken to the CT scanner where a needle is inserted into the lesion and several biopsy samples are taken.

On average, CT-guided biopsies last 45 minutes to an hour. This time varies according to the location of the lesion. Please be aware that this time does not include the time you spend in the holding area both before and after the procedure. Overall, your procedure duration may be several hours. Please arrange to have someone available to drive you home.

Procedure Complications

The procedure is relatively simple and safe, and every attempt is made to avoid complications. However, there are associated risks. These include bleeding, injury to a nerve, infection, and allergic reaction to contrast or medication.

After Treatment Care

Pain resulting from the procedure usually resolves within a few days. Normal activity can typically be resumed the day following the procedure.

It typically takes several days for the tissue sample to be processed to determine the diagnosis. Results of the biopsy are normally obtained from your primary physician.
