AVTDI Advanced Skills Requirements

All qualified candidates will have demonstrated advanced diagnostic imaging skills in a variety of species for veterinary imaging patients.

To show knowledge and mastery of imaging techniques, advanced skills may be performed on a wide variety of species of veterinary patients. Appropriate veterinary patients for imaging include:


  • Small animal species (Feline, Canines & Exotics)
  • Large animal species (Equine, Camelids & Farm animals)
  • A combination of small and large animal species

All qualified candidates must show proficiency in three (3) skills categories and must complete the veterinary diagnostic imaging skills form. The mastery of these skills is considered essential knowledge for diagnostic imaging technicians.

AVTDI defines mastery as: the candidate can perform the task safely and consistently, without being coached or directed, no less than three (3) times. Mastery requires having performed the task in a wide variety of patients and situations.

Candidates must complete a minimum of 75% of section A (general radiology), 50% of section B (advanced imaging and contrast examinations) and 50% of section C (nursing and pharmacology/supplemental imaging).

Skills performed can be in multiple species categories for imaging modalities. Applicants are encouraged to use non-manual restraint methods where applicable.

Section A (General Radiology) Skills:
  • Minimum 75% skills must be completed
    • Skills may be represented by small animal, large animal, or a combination of both.
  • Minimum ten (10) skills represented in case logs/report
Section B (Advanced Imaging and Contrast Examinations) Skills:
  • Minimum 50% skills must be completed
  • Minimum twenty (20) skills represented in case logs/report
Section C (Nursing and Pharmacology/supplemental Imaging) Skills:
  • Minimum 50% skills must be completed
  • No minimum requirement for case logs/reports

Mastery of a skill versus assisting should be indicated by the approved signer on the skills sheet as well as the use of manual restraint verses non-manual restraint techniques where applicable.

The Organizing Committee acknowledges that there are certain skills that may not be allowable in certain states and therefore, assisting in those skills would be acceptable. Documentation of assistance in a skill for this reason should be noted on the corresponding case log.


Approved signers for mastery of skills include:

  • A Doctor of Veterinary Medicine who is a Diplomate of the ACVR (American College of Veterinary Radiology) and/or a Diplomate of the ECVDI (European College of Veterinary Diagnostic Imaging),
  • A Senior third year ACVR/ ECVDI Residents,
  • A Doctor of Veterinary Medicine who is a Boarded Specialist in Internal Medicine, Neurology, Surgery, Oncology or Emergency and Critical Care that perform advanced imaging modalities will be acceptable,
  • AVTDI members,
  • If no AVTDI members are available then a NAVTA approved credentialed VTS technician of Internal Medicine, Neurology, Surgery, Oncology or Emergency and Critical Care that perform diagnostic imaging studies and/or advanced imaging
