You need to arrive at the hospital two hours before your appointment to have aCT scans. This will allow time for you to drink barium sulfate before your exam and to make sure that the barium fluid is completely dissolved. You will be asked to lie on your back with your knees bent and your feet flat on the floor. Your doctor will ask you a series of questions about your medical history, symptoms, and general health.
He or she will then perform a physical examination, including a chest X-ray and a pelvic exam. If your doctor suspects that you may have a medical condition that requires further evaluation, such as a heart condition, a blood clot in your leg, or an infection, the doctor may order additional tests to rule out these conditions. You may also be given medications to help control your symptoms.
