The patient is to fast (not eat or drink anything) for 6 - 8 hours prior to the exam and arrive 15 minutes before the scheduled procedure.

What to Expect:
Upon arrival to Radiology Reception, you will be greeted and escorted to the Nuclear Medicine suite by one of our team members.  There your Technologist will explain the procedure, discuss symptoms (if any) along with medical history and start an IV in vein in the arm (or hand). 

A small amount radiopharmaceutical is injected through the IV.  The injection has no side affects and you will have no sensation at all.  you are asked to drink extra fluids following the injection and to empty the bladder as often as possible prior to the second appointment, for the actual scan.

The scan takes approximately 60 minutes.  Your Technologist will position you on the imaging table.  Then the camera is positioned above your abdomen and will begin imaging  to see how the gallbladder takes up the injected material.  The scan itself takes 60 minutes.  For maximun comfort, a pillow is placed under the head and the knees and you are covered with a warm blanket.  Feel free to bring along your favorite DVD movie or music CD or you may choose one from our selection. 

The length of your scan is determined by how fast your gallbladder process the radiopharmaceutical.  Since each patient functions differently, the images take varying amounts of time.  Your Technologist will keep you informed throughout the duration of your procedure.

Once the images are acquired, your Technologist will evaluate the images for quality, remove your IV, address any issues or concerns you may have and escort you back to the reception area.  The images are read by a Radiologist (doctor) and the results are dictated, transcribed and sent to the ordering physician within 3 business days.  The ordering physician will provide results to you.

Common reasons to perform a HIDA Scan include (but are not limited to):

  • Evaluation of cholecystitis
  • Evaluation of gallbladder stones
  • Detection and perforation of the gallbladder
  • Evaluation after gallbladder surgery for suspected leakage
