Image-guided biopsies are IR procedures that use imaging technology to aid in the sample collection process. During such procedures, an interventional radiologist uses x-ray, CT, or MRI to collect a sample of abnormal tissue or masses to test for cancer. This can also be used in the case of abscess drainage.

Before Your Exam

Before an image-guided biopsy, talk to your doctor about any medications and follow his or her advice on which you can still take. You may be advised to stop taking NSAIDs before the procedure. Refrain from eating or drinking several hours beforehand.

Time required for your exam

This procedure typically takes between 45 and 60 minutes.
