Description of Examination: 4 hours exam. Questions will cover radiation safety and radiobiology. In addition questions may cover the modalities X-ray imaging (radiology), ultrasound, CT, MRI and scintigraphy. Questions on all modalities will evaluate an understanding of the underlying imaging principles and on x-ray and ultrasound imaging will test understanding and skills required to evaluate clinical images is small and large animals.

Course Content
Basis of conventional radiographic imaging· Production of x-rays· The x-ray spectrum· Manipulation of the spectrum of x-rays emitted from diagnostic x-ray tubes· Interaction of x-rays with matter· Compton and photoelectric effects· Concepts of radiographic density· Causes of poor image contrast with emphasis on scattered radiation.· Image sharpness· Radiographic image detectorsBasic radiography· Production of optimal radiographic images.· Positioning and technical aspects relating to correct positioning and exposure for standard views of the skeleton, thorax and abdomen in veterinary species.· The use of appropriate radiographic terminology.Radiographic anatomy/topographic anatomy:· The common anatomical features within various body regions including the head, neck, thoracic and pelvic limbs, the thorax and abdomen, that are of relevance for the interpretation of diagnostic images produced by the range of modern imaging modalities. Special focus will be put on images from the dog, cat and horse. Radiation safety and radiation biology· The nature of x-rays as an ionizing radiation, the effect of these radiations on biological tissue, and the relation between tissue dose and biological effect. Examples of tissue effects based on dose response. · The legal requirements in relation to work related exposure of personnel to ionizing radiation as a result of imaging and therapeutic uses of these radiations. Dose limits and the "ALARA" (As Low As Reasonable Achievable) principal.· The appropriate radiation safety steps, with practical examples relating to work practice and work place infrastructure, based on Danish legislation in this area. Ultrasound MRI, CT, and ScintigraphyPhysical basis of the various modalities:Ultrasound imaging:· Nature of ultrasound beams· Effect of insonation frequency on image quality· Physical basis for tissue echogenesity· Brightness mode imaging· Doppler imaging· Concept of cross sectional imaging· Examples of clinical applicationsComputer tomography:· Cross sectional and planar reconstruction · The CT number, linear attenuation coefficients for x-rays and the Hounsfield Unit.· Digital image windowing, window width and centre.· Examples of clinical applicationsScintigraphy:· Radioisotopes with emphasis on 99Tcm· Radiopharmaceuticals · Examples of clinical applicationsMagnetic resonance imaging:· Hydrogen as a magnetic dipole· Magnetic gradients· Radiofrequency coils· Relaxation properties of tissues· Basis of image generation· Examples of clinical applications

Learning Outcome
Knowledge:
·Be able to comment on the suitability of various imaging modalities in response to selected clinical scenarios.
·Comment on the risk associated with radiographic practice and relate them to commonly encountered, non-radiological risks.
·Identify features indicating correct patient restraint, positioning, beam collimation and focusing in standard radiographic views, and comment on digital image or film processing as appropriate.
·Recognise images produced by each of the methods, scintigraphy, CT, MRI.
Skills:
·Be able to produce a selection of common radiographic projections in a safe manner from canine, feline and equine patients.
·List the radiographic changes that are commonly encountered in common diseases in dogs, cats and horses.
·Speculate on the changes one might expect to encounter given various disease scenarios.
·Identify abnormal radiographic findings on radiographic images in selected cases.
·Demonstrate a methodical approach to image evaluation.
·Recognize and find normal abdominal and thoracic structures commonly encountered in ultrasound examinations
