Mark Bernstein, M.D., is assistant professor of radiology and trauma/emergency radiology at New York University Medical Center/Bellevue Hospital. Fascinated by the pivotal role diagnostic imaging can make in the care of acutely ill and injured patients, he had pursued a fellowship in trauma and critical care imaging at the University of Maryland's Shock Trauma Center in Baltimore. Emphasis was placed on a multi-modality approach (XR, CT, MR) to the diagnosis of critically ill traumatized patients. Dr. Bernstein developed a particular interest in the ever-growing role of CT, and now multi-detector CT, in assessing stable blunt and penetrating trauma victims. He compiled a series of trauma protocols for the Bellevue Emergency CT scanner and patients can now get a complete diagnostic workup in just a single visit to the CT scanner. Most of his interest lies in cervical and thoracolumbar spine injury evaluation, and the CT diagnosis of vascular injury including aortic injury.

Dr. John's primary research interests have involved the use of imaging for diagnosis of children in the emergency and acute care setting. Ultrasound is a special area of interest. She is an advocate for the use of ultrasound in evaluation of the causes for acute abdominal pain in children, such as appendicitis, mesenteric adenitis, intussusceptions, Henoch-Schoenlein purpura and various inflammatory conditions of the gastrointestinal tract. She has also investigated the use of ultrasound for cystic renal diseases and soft tissue masses in children. Pediatric musculoskeletal ultrasound and radiographic evaluation of acute musculoskeletal injuries and diseases are also areas of strong interest. She frequently lectures on pediatric elbow injuries. A third area of interest is acute abnormalities of the pediatric airway and lung, with particular attention to bronchial inflammatory conditions.
