An orthopantomogram of the pelvis is the normal, most common radiographic examination. It usually requires the patient to remain in an upright position with the front of the body facing the movable radiographic probe and the back of the body leaning against a non-movable back wall. These normal radiographs are quick, low radiation, inexpensive, and can detect many lesions in the pelvis and lower abdomen, thereby ruling out many diseases. Patients who are suspected of having a pelvic fracture or who have suffered a traumatic injury to the pelvis and are unable to move need to be placed in a flat supine position. In most regular hospitals, the radiology machine is mobile and allows the patient to remain in a standing position or in a flat supine position. Many kinds of diseases, including orthopedic, medical, surgical, and anorectal, require pelvic orthostatic examinations.
