Your doctor has requested a CT-guided biopsy. This is a minimally-invasive procedure that can usually be done without an overnight stay in the hospital. During a biopsy, one of our physicians will use images generated by a CT scanner (also called a Cat scan) to accurately insert a needle into the suspect tissue, allowing a sample to be removed for testing. The CT scanner uses x-rays and advanced computer programs to create detailed images inside your body.
Current blood tests (BUN and Creatinine) are required prior to your biopsy; as are tests for PT, PTT and platelets. You should discuss these tests with your referring physician prior to the day of your biopsy.
Do not to eat or drink anything after midnight prior to your exam. (If you are diabetic, you should talk to your referring physician prior to the day of your exam. You may receive special instructions with regard to medications and diet. Do not alter your diet or medications without being instructed to do so by your physician.)
Do not take aspirin or aspirin-related medications for 7 days prior to your procedure. You should discuss any changes to your medications with your physician.

You will not be allowed to drive the day of this procedure, so please arrange for someone to drive you home.
You should expect to be at the imaging center for approximately 6 hours, longer if blood tests are needed.
A radiology nurse or technologist will ask you a few questions regarding your medical history, they will also do a few simple tests such as taking your blood pressure.

You will be given a local anesthetic. This will only numb the area around the site of the procedure. You will remain fully awake.
The table you are on will slide into the scanner. This process usually includes multiple scans, so you will likely slide into the scanner more than once.
The scanner is open at the back and the front, allowing you to see out. The technologist will always be able to see and hear you during your exam.
You will be asked to hold very still and at times to hold your breath.
The imaging physician will perform the biopsy and remove a tissue sample.
This biopsy itself usually takes approximately 15-30 minutes.

The tissue sample will be sent to a laboratory for examination. Results from the test will be sent to your physician, usually within 48 hours.
