Radiology Resident Training Program

For more information about our training program, please contact Dr. Martha Larson at moonm@vt.edu or 540-231-4815.

Program Overview

Veterinary radiology is a well-developed subspecialty in veterinary medicine and, as such, is recognized by the American Veterinary Medical Association. Veterinary radiologists have a high level of expertise in not only conventional radiography, but also special diagnostic procedures, nuclear medicine, computed tomography, magnetic resonance, and ultrasound.

Our department offers a combined residency-master's program in veterinary radiology. The purpose of the program is to train residents to become future teachers, investigators, and clinicians in Veterinary Radiological Sciences. The 4-year program is fully accredited by the American College of Veterinary Radiology (ACVR) and is designed to meet all eligibility requirements for board certification. The program is also designed to meet all requirements for completion of a Master of Science degree. An individual successfully progressing through the program will be eligible to sit the written part of the qualifying examination of the ACVR during the third year of the program.

Individuals applying for admission to the program should have completed an internship program or at least one year of veterinary practice and be eligible for admission to the graduate school programs of VA-MD Vet Med and Virginia Tech. Successful applicants must take and pass the campus radiation safety examination within 30 days of the start of the program.

Objectives

  • To help the resident learn the basics of radiobiology, radiation physics, radiation protection, radiation dosimetry, and radiation safety.
  • To help the resident develop clinical skills in diagnostic radiology in both large and small animal patients, utilizing both conventional radiographic examinations and special procedures.
  • To help the resident learn the basic principles of and clinical applications for ultrasound, computed tomography, magnetic resonance imaging, and nuclear medicine.
  • To provide guidance in the design, data collection, data analysis, and publication of a research project.
  • To provide training that will serve as a basis for future research endeavors.
  • To provide experience in teaching radiological sciences to veterinary students and veterinary practitioners.
  • To reinforce professional and ethical behavioral characteristics, and appropriate work ethic standards.

Training & Supervision

Forty-eight months of supervised post-doctoral training in veterinary radiology is required. Continuation into the second, third, and fourth years of the program will be dependent on the resident's performance evaluations.

Dr. Martha Larson, Diplomate ACVR, is the residency program director. She is actively involved in the training and instruction of residents.

  • Assist in the instruction of fourth year veterinary students and house officers in interpretation of routine and contrast radiographic examinations, CT and MRI evaluations, ultrasound examinations, and nuclear medicine procedures
  • Be required to assist in presentation of seminars within both the radiology section and the department

The bulk of the training comes through seminars, daily rounds with radiology faculty, chapter and article reviews, and formal courses. The resident is encouraged to participate in continuing education short courses and to give seminars at local, state, and national meetings during the period of residency. Presentation of at least one paper at an ACVR meeting is expected.

Research & Teaching

A grant proposal, completed research project, and oral presentation at the Annual Meeting of the American College of Veterinary Radiology, and at least one major manuscript submitted to a refereed journal and completion of a Master's thesis is required. Guidance in these endeavors is provided by the resident advisor, major professor, and graduate committee. In addition, the resident presents a seminar each year to the faculty and house officers of the Department of Small Animal Clinical Sciences as part of the department's Resident Seminar Program. A presentation at the college's Annual Research Symposium is encouraged.

The resident assists in instruction of fourth-year veterinary students and participates in didactic courses offered to first, second, and third-year veterinary students. This includes lecture and laboratory preparation and presentation of material in gross anatomy (radiographic anatomy) and in the diagnostic radiology courses. The resident presents 1 seminar each year as part of the department's resident seminar series. The resident attends Pathology rounds each week and is responsible for the presentation of related radiographic material.

Conferences

The resident participates in the daily clinical schedule in conjunction with one of the radiology faculty and is expected to attend and participate in resident seminars and radiology resident rounds. Attendance by the resident at regional and national meetings is encouraged. Extramural radiology training at other institutions is encouraged.

Evaluation

Each resident is reviewed semi-annually by the radiology faculty and is provided with a written analysis of the resident's abilities and productivity. Input is sought from staff, faculty, and house officers from other sections. The review is discussed with the resident at a formal meeting with the resident advisor.
