The technician will assist you onto the scanning table. You will lie on your back, relaxed, with your head on a pillow and the patient table will then slide very smoothly into position. You will have to stay still during the exam so the technologist can get an accurate image. You can expect the exam to last 30 minutes. After the exam, the technician will lead you back to the dressing room where you can retrieve your personal belongings. Results of the scan are provided to your doctor within 24 hours.
