What department to register for an ultrasound examination depends on the specific purpose of the patient’s examination, and the specific area to be examined. If the patient only wants to have an ultrasound for a physical examination, he or she can register for the physical examination department, the general internal medicine department, and the convenience clinic number. If a patient needs an examination because of certain clinical symptoms, it depends on the patient’s specific situation. If a patient has a gynecological disease and needs an ultrasound examination of gynecology, he or she can register with the gynecology department. If the patient has a heart problem, he or she can register for cardiology or cardiac surgery. If the patient is suffering from abdominal pain, he or she can register for gastroenterology or infectious disease. If the patient has a problem with the blood vessels of the lower extremities, he or she can register for vascular surgery.
