Weissflog, Nina (2005): Multimediales Lernprogramm über die Sonografie von Harnblase, Nieren und Nebennieren bei gesunden Hunden und Katzen. Dissertation, LMU München: Tierärztliche Fakultät



Ultrasound evaluation of the urinary bladder, kidneys and adrenal glands including Doppler ultrasonography of the blood vessels, still remains difficult for many veterinarians. Particularly the physician with little experience has problems with the visualisation of these organs and also with the interpretation of the different ultrasound images. The objective was to develop a multimedia program that presents the sonographic basics of the urinary bladder, the kidneys and adrenal glands in a clear and detailed way as well. Small, medium and large healthy dogs and cats were used for obtaining the ultrasound stills, videos, and also for the scanning procedure. The ultrasound images and films were produced with different ultrasound systems with linear- and konvex scanner (transmitting frequency between 5 and 12 MHZ). The source code was made with HTML, which is equipped with javascript applets, JPEG stills and MPEG1 films. The program includes the organ topography, the transducer positioning and the two dimensional B-Mode of the urinary bladder, kidneys and adrenal glands. The demonstration of the Doppler sonography of the extra- and intrarenal vessels is intended as an advanced training for already experienced physicians. The structure of the program is designed with regard to didactic and ergonomic aspects. The high resolution of all typical ultrasound images and films could be seen with or without a legend, in a small or large format and could be printed. Video clips about the visualisation of the organs, photos with anatomic preparations, and colourful diagrams explain the production and the interpretation of ultrasound images. The user can navigate through the program in different ways. It is recommended that physicians with little experience go through the program page by page. A clearly arranged menu, a comprehensive index and linked text passages or pictures makes it possible to move easily through the program. All pages are marked to help you keep track. The scanned images of either the dog or cat can be viewed separately in comparison. This program offers physicians with little experience as well as advanced investigators the possibility of learning the basics of ultrasound including the Doppler sonography of the urinary bladder, kidneys and adrenal glands in a comprehensive way.
