Written Paper I: This paper is designed to test the Candidate’s knowledge of the principles of Veterinary Diagnostic Imaging as described in the Learning Outcomes. Answers may cite specific examples where general principles apply, but should primarily address the theoretical basis underlying each example. Questions may be of any type including short answer, multiple choice and essay based questions. Written Paper II: 4 This paper is designed to (a) test the Candidate’s ability to apply the principles of the Veterinary Diagnostic Imaging to particular cases/problems or tasks, and to (b) test the Candidate’s familiarity with the current practices and current issues that arise from activities within the discipline of Veterinary Diagnostic Imaging in Australia and New Zealand. Questions may be of any type including short answer, multiple choice and essay based questions. Practical examination: The practical examination will be conducted in two sessions, each approximately 3 hours (for a total of ~6 hours). The examination will cover interpretation of radiographs, ultrasound, CT, MRI, nuclear medicine, special procedures, and their artifacts. The emphasis will be on the core species (canine, feline, equine); however, cases from any species may be included. Oral examination: Refer to Blue Book TRAINING PROGRAMS Refer to the Blue Book Section 4.3 In addition to the stipulations of the Blue book: 1. The Radiology Chapter requires a three year training program (144 weeks) 2. Clinical training should include primarily exposure to dogs, cats and horses with some exposure to ruminants, camelids, exotic animals and birds. 3. Clinical training should include the following: radiography, radiology, contrast procedures, fluoroscopy, digital radiography, sonography, sonology, scintigraphy, computerised tomography and magnetic resonance imaging. 4. The candidate should interpret a minimum 3000 radiological examinations of small animals (primarily dogs and cats), 500 radiological examinations of large animals (primarily horses), 1000 sonographic examinations, and a minimum of 100 examinations that demonstrate adequate knowledge and interpretive skills in CT, MRI and nuclear medicine. The cases to be included in the case log will be those cases in which the candidate has produced a written report. If, for example, a case has an osteosarcoma of its radius and thoracic radiographs for a metastasis check then this may be counted as two cases if a report is produced for both regions. The training program should be targeted, with achievable goals set by the Supervisor and candidate for each 6 months. It is anticipated that the first year should be spent initially learning some radiography, then concentrating on radiology and ultrasound with some exposure to the other modalities. The second year is spent consolidating the first with more CT, nuclear medicine with shifting emphasis in the third year to more CT and MRI and nuclear medicine with further consolidation of radiology and 5 ultrasound. It should be expected that the candidate’s case log output is lower in the first year but that they become more independent and productive in their second and third years. Sonography and Sonology Assessment: The candidate’s supervisor will continually assess the Candidate’s development of sonography and sonology skills. If the Candidate’s skills were found to be less than satisfactory at the end of the third year of their approved training program, the Candidate will be required to undertake further training before being further assessed. The Candidate will not proceed to formal examinations until they have been determined to have adequate sonography and sonology skills. A pro-forma letter will be completed by the Candidate’s supervisor and submitted with the Fellowship training credentials documentation, to state whether the Candidate is considered technically proficient in ultrasound, and to justify the reasons for the assessment. TRAINING IN RELATED DISCIPLINES Refer to the Blue Book Section 3.4.2. Candidates for Fellowship in Veterinary Diagnostic Imaging must spend time as stipulated by the Blue Book in any four of the following related disciplines: Clinical Pathology, Small Animal Medicine, Cardiology, Small Animal Surgery, Equine Medicine, Equine Surgery, Neurology, Oncology. EXTERNSHIPS Refer to the Blue Book Section 3.4.1. ACTIVITY LOG AND ACTIVITY LOG SUMMARY Activity log categories The Activity Log should be recorded using Blue Book Appendix 8.5. The Activity Log Headings should be as follows: Date Category (Species) Patient Details Details of Imaging Study Performed Diagnosis Confirming Pathologic or Other Findings Activity log summary An Activity Log Summary should be provided for each imaging modality (Radiology, Ultrasound, Special Radiographic Procedures, CT, MRI and Nuclear Medicine) according to the attached template. Each summary should contain case numbers for a 6 month period. For each imaging modality, cases are recorded by species and the region imaged (as listed below). This allows the candidate and their supervisor to monitor their case load for each modality (e.g. numbers of canine abdominal ultrasounds, numbers of equine musculoskeletal radiographs, etc), and assess whether the targets mentioned above (section 4 in the Training Programs heading) are being achieved. 6 Radiology: Thorax Abdomen Musculoskeletal/Neurological Other Ultrasound: Thorax - non cardiac Thorax - cardiac Abdomen Musculoskeletal Small Parts (eg thyroid, eye, etc) Biopsies/FNA Special Radiologic Procedures: Myelography Urinary contrast studies Oesophagrams Other contrast studies Fluoroscopy (non-contrast) CT: Thorax Abdomen Musculoskeletal Neurological MRI: Neurological Other Nuclear Medicine: Musculoskeletal Thyroid Hepatic Other Species list for each modality: Canine Feline Equine Bovine Ovine Avian Other Note that an imaging study of a region is considered a case. If multiple regions are imaged of a single patient (e.g. radiographs of a long bone and thorax for metastasis 7 check) these would be considered two cases; one musculoskeletal and one thorax – non cardiac, provided both are reported. PUBLICATIONS Refer to the blue book Section 3.11. RECOMMENDED READING LIST The candidate is expected to research the depth and breadth of the knowledge of the discipline.
