For Healthcare Professionals

Dartmouth-Hitchcock offers imaging services at many locations around the region.  See our locations or Appointments and Referrals page for more information.

Dartmouth-Hitchcock Medical Center in Lebanon has several Clinical Divisions, listed below. There are also several Educational opportunities.

Dartmouth-Hitchcock Medical Center (Lebanon) Clinical Divisions 


DHMC offers several Graduate Medical Education programs, including a Radiology Residency and Fellowships in MRINeuroradiology, and Vascular and Interventional Radiology (VIR), which are designed to supplement the resident experience. Our faculty also plays a major role in the The Geisel School of Medicine at Dartmouth curriculum.

Residency Training Program

The Radiology residency is a competitive four-year program that attracts top-notch candidates from around the world. We offer cutting-edge facilities and an array of research opportunities. The residency has a 2:1 faculty-to-resident ratio, and our staff is actively involved with research and teaching.

To learn more, visit the Radiology Residency Program on our Graduate Medical Education website.

Medical Student Education

Our faculty plays a major role in the The Geisel School of Medicine at Dartmouth curriculum, with multi-year courses intended to advance several overlapping goals: the effective use of medical imaging resources as learning tools in the clinical curriculum; a thorough introduction to the purposes and methods of modern radiology; and, for interested students, a clinical electives program designed to provide an in-depth understanding of the appropriate uses of medical imaging and interventional procedures, exam methodologies, the basics of image interpretation, and costeffective image management.

The Geisel School of Medicine Human Anatomy
website receives roughly 100,000 hits/month.

Some measure of the program's ongoing success can be found in a number of quantifiable achievements. Basic Clinical Radiology, our fully-subscribed fourth-year elective, is one of the most popular Geisel School of Medicine electives, chosen by roughly 60% of all students. The number of our students electing radiology residencies remains large—averaging over 9% in the past decade, significantly above the comparable 6% national rate—and shows little sign of abating, as witnessed by the 14% of the Geisel School of Medicine class of 2009 who chose residencies in radiology. And finally, we cannot help but take pride in the fact that for each of the past eleven years, our students seeking radiology residencies have succeeded in a 100% match rate.

First and Second Year Courses

The first-year anatomy curriculum includes Dr. McNulty's classes on anatomical- radiological correlation, and routinely utilizes the lessons and image-database of the radiology component (designed by Dr. McNulty) of the Geisel School of Medicine Human Anatomy website. The second year's Scientific Basis of Medicineprogram includes a nine-hour introduction to medical imaging and the pathophysiological basis of imaging abnormalities. Additional radiology opportunities for first and second-year students include the eight-week informal Spring Elective in Radiology and regular Radiology Interest Group meetings.

Clinical Electives

The centerpiece of our program is Basic Clinical Radiology, a four-week elective offered in any of four blocks during the fourth year, and in a fifth block available to third-year students. Designed for both future radiology residents and for students aiming at other specialties, the elective includes exposure to all areas of diagnostic and interventional radiology. Radiology residents take an active role as instructors in the program—an involvement which we believe enriches the educational value of the elective for residents and students alike. Specifically, the elective covers the advantages and limitations of the key imaging modalities; the clinical basis for appropriate imaging requests; how images are obtained and procedures are performed with the goal of understanding patient selection and suitability; how to provide informed advice to patients; how imaging is incorporated into logical medical problem solving; and the basics of radiological interpretation as applied to routine and emergency medical practice. The elective includes individually-tailored clinical rotations through the subspecialty areas, as well as student presentations and workshops. Students are expected to spend an evening on call with one of the residents, and to take advantage of the department's extensive electronic and web-based resources during the scheduled blocks reserved for self-teaching. Image management workshops, and lively interactive sessions including "image jeopardy" and an "imaging lingo" conference form an additional part of a curriculum designed to emphasize multiple teaching methods. For the duration of the elective, students are welcomed to participate in all academic and social activities of the department.

In addition to this basic clinical elective, fourth-year students may choose from several shadowing-type electives. These 2 to 4 week courses are limited to one or two students and include the highly personalized Flexi-Elective; subspecialty electives in neuroradiology, interventional radiology and women's imaging; and a research elective which forms the basis for short or long-term research projects which students are encouraged to undertake.

Education Leadership

Radiology education for medical students is directed by Dr. Petra J. Lewis (Program Director and Years 3-4 Coordinator) and Dr. Nancy J. McNulty (Years 1-2 Coordinator). Drs. Lewis and McNulty are advocates for the use of electronic and web-based technologies, with respect to both the application of radiologic resources to all areas of medical student education, and for medical imaging instruction specifically. Working together or individually, they have developed a number of online resources for medical student education:

  • The Basic Clinical Elective utilizes a Blackboard™-based collection of web-based teaching files, scheduling applications, evaluation tools, and the final exam.
  • Human Anatomy Learning Modules is a popular (100,000 hits/month) web-based curriculum now incorporated into the Geisel School of Medicine anatomy curriculum (and at U. Penn and U.S.C.) Dr. McNulty created and continues to develop the site's radiologic component. (
  • Radiology ExamWeb, part of a national initiative for standardized testing in radiology, was designed by Drs. Lewis and McNulty; funded by the RSNA and the Hudson Foundation, the project now includes 22 institutions nationwide. (
  • CORE (Case-orientated Radiology Education) is a web-based radiology curriculum for 3rd and 4th year medical students; developed by Dr. Lewis, CORE is now used throughout the medical school curriculum for case-based simulations and problem-solving exercises within the surgery, pediatrics, medicine and neurology clinical clerkships.
  • The AMSER Shared Resources website, developed by Dr. Lewis and available to all AMSER members, includes a multi-institutional database of images which have been found useful in teaching, and a separate database of shared documents including curricula, lectures, exams, games and other resources. (

In addition, a web-based teaching file application under development by Dr. Siegel, with support from a Geisel School of Medicine Venture Fund grant, will become a significant additional resource upon implementation later this year. Both Drs. Lewis and McNulty are active with national organizations dedicated to medical student and residency education. Dr. Lewis served as president of the Alliance of Medical Student Educators in Radiology (AMSER) in 2006-2007, and now chairs its Electronic Communications Committee. Dr. Lewis holds committee assignments at the Association of Program Directors in Radiology, at the American Board of Radiology (various faculty and resident certificiation committees), and at USMLE/NBME (the Anatomy and Embryology Exam Committee). Dr. McNulty is similarly active in national medical education organizations, and serves currently as President of AMSER.
