Gastrointestinal Radiology

GI Radiology's success depends on our teamwork, and on close collaboration with the departments of Gastroenterology, General Surgery, and Internal Medicine. Weekly CME-accredited multidisciplinary GI conferences, at which students may participate, feature diagnostic and therapeutic issues in a case-based format, and selected clinical advances presented by subspecialty experts. The performance of imaging studies in a focused, expedient, and logical progression is one positive outcome of this multidisciplinary conference. Local physicians from outside the institution also participate at the conferences, as do visiting professors of gastroenterology, surgery and radiology.

Exams are performed in three fluoroscopy suites, on pulsed digital systems (Philips EasyDiagnost™ Eleva) providing rapid, efficient studies while minimizing radiation exposure. Digital fluoroscopy with image transfer to PACS improves efficiency, communication, and cost effectiveness. Our concurrent use of real-time fluoroscopy, captured on DVD, lets us further decrease radiation exposure, as well as expediting review, documentation, teaching, and communication with referring physicians. Our radiologic technicians are highly regarded—Philips Medical rates the Diagnostic Core and its staff as a "luminary site," and several technologists hold "clinical super user" recognition for above-average knowledge and skill. The division is committed to safe, child-friendly care, and works closely with the Children's Hospital at Dartmouth-Hitchcock (CHaD). We actively participate in CHaD's Pain-Free Program, and in the Image Gently campaign, an initiative by the Alliance for Radiation Safety in Pediatric Imaging that seeks to raise awareness of the opportunities to lower radiation dose in children's imaging. Maintaining a reassuring environment is also a priority, and the section has enthusiastically taken on the responsibility of making the visits of our pediatric patients as comfortable and pleasant as possible.

We continue to implement the core curriculum in GI Radiology. Presentations by department faculty are supplemented by visiting professors, New England Roentgen Ray meetings, and Grand Rounds. One-on-one review of teaching file cases remain a very useful and popular part of the fluoroscopy rotation and Dr. Chertoff 's experience as a GI examiner for the American Board of Radiology examination enhances the review sessions held for the senior residents.

The delivery of high-quality care to patients with complex disorders requires close coordination of services provided by various departments; the New England Hepatobiliary Disease Center—a collaboration between DHMC gastroenterologists, surgeons, and radiologists—was developed to meet this need. The Center's goals include state-of-the-art diagnostic and therapeutic services, the promotion of research on hepatobiliary diseases, and hepatobiliary disease education and data sharing.

Division director Dr. Chertoff plays an active leadership role at DHMC and DMS. She chairs the Board of Directors of the Hitchcock Foundation; is Co-Vice Chair of the Commission on Education at the American College of Radiology (and is directing development of the gastrointestinal portion of the core ABR exam); and holds key positions in medical education organizations including the Alliance of Clinician-Educators in Radiology, the AUR, the Association of Program Directors in Radiology (APDR), and the Accreditation Council for Graduate Medical Education (ACGME).
