Our full complement of services includes ultrasound studies for the following: Upper and lower extremity arterial disease Venous insufficiency Rule out DVT scans Carotid and vertebral artery disease Abdominal aortic aneurysm screening Raynaud's testing Thoracic Outlet Syndrome Mesenteric and renal artery disease These studies evaluate hemodynamics, vessel anatomy, and flow direction, which provides us with critical diagnostic information. Our laboratory will perform “STAT” studies within 2 hours of the request. For elective studies, referring physicians can expect scheduling within 1-2 weeks, a preliminary report faxed to the office the same day as the study, and a formal report faxed within 1 business day of the test being completed.
