SVEK13003U Veterinary Imaging
The course comprises the following elements:
Basis of conventional radiographic imaging
· Production of x-rays
The x-ray spectrum including manipulation of the
spectrum of x-rays emitted from diagnostic x-ray tubes and
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 detectors.
Basic 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 from the limbs of
the 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, including examples of
tissue effects based on dose response and 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 Scintigraphy · the physical 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 applications Computer 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 applications Scintigraphy:
· Radioisotopes with emphasis on 99Tcm
· Radiopharmaceuticals
Examples of clinical applications Magnetic resonance
imaging:
· Hydrogen as a magnetic dipole
· Magnetic gradients· Radiofrequency coils
· Relaxation properties of tissues
· Basis of image generation·
Examples of clinical applications
Knowledge:
·Identity and name relevant normal and abnormal anatomical
structures on images produced by different imaging modalities.
·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.
·Identify normal and abnormal radiographic findings on radiographic
images in selected cases commonly encountered in veterinary
practice
·Recognize and find normal abdominal and thoracic structures
commonly encountered in ultrasound examinations
·Perform a standard radiological examination.
.Demonstrate a methodical approch to image evaluation of
radiographs, and ultrasound.
·Choose the appropriate imaging modality for common clinical
presentations.
Competencies:
·Speculate on and discuss the changes one might expect to encounter
given various disease scenarios.
·Behave in accordance with the legislation (Bekendtgørelse om
