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 Exect:
The procedure will last about 2 hrs. Upon arrival to Radiology Reception, you are 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 the patient will have no sensation at all. The patient is 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 60 minutes. Your Technologist will position you on the imaging table. Then the camera is positioned above yourabdomen 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 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 a differently, the images may take varying amounts of time. Your Technologist will keep you informed throughout the duration of your procedure.
After approximately 60 minutes of initial imaging, the technologist will contact a Radiology Nurse to inject a medication (Kinevac). Kinevac is a medication that causes the gallbladder to contract. The Kinevac will be injected through an IV pump over 30 minutes during which time, the technologist continues to image the gallbladder. The Kinevac sometimes makes people feel a slight cramping sensation, but most people say they don't feel anything at all. Make yourtechnologist aware of any discomfort and he/she will work to ensure your comfort. Any symptoms experienced will be resolved as soon as we stop the injection of the Kinevac.
Once the images are acquired, your Technologist will evaluate the images for quality, remove your IV, address any issues or concerns that 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 the patient.
