Most patients who are seen by Mallinckrodt Institute radiologists and nuclear medicine physicians are referred by a physician from another specialty, such as a cardiologist.  Most radiology and nuclear medicine tests and treatments require a referral from your doctor and must be scheduled in advance.  Some tests, such as screening mammography, do not require your doctor's authorization, but you must call to schedule an appointment.

For more information, call Radiology General Scheduling at (314) 362-7111. Office hours are Monday through Friday, 7:00 a.m. to 5:30 p.m.
