Preparation for Procedure

  • Inform your physician of any recent illness
  • You will wear a gown during the exam and will be asked to remove jewelry, dentures, eye glasses and any metal objects or clothing that might interfere with the x-ray images.
  • Women should always inform the radiology staff if there is a possibility that they are pregnant.
  • Your physician may advise you to stop taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) or a blood thinner for a specified period of time before your procedure.
  • Prior to your procedure, your blood may be tested to determine how well your liver and kidneys are functioning and whether your blood clots normally.
  • You will be given sedation so you must not have anything to eat or drink anything for six hours before your exam. Most patients will stay the night in the hospital to make sure their pain is well controlled that first night.
