Methods of Visualization for Diagnostic Aneurysmats Abdominal Aorta
SEDLÁČKOVÁ, Eva
Abstract Methods of Visualization for Diagnostic Aneurysmats Abdominal Aorta The subject of my work is to define frequency of individual methods of vizualization which are used to diagnostic aneurysmats abdominal aorta. The work contains also a research which enabled me to get a view of the role of radiographics at work. The questionnaire which should have found out the role of radiographics during CT and MR angiography, the instrumentaion of the individual working places and some technical parameters passed through at first. The obtained data were worked up two ways and the questionnaire was analysed. The second part of my work was to define the frequency of single methods of vizualization for a certain collection of patients. With the help of data, which were obtained from the system PACS in Nemocnice Na Homolce, the frequency of examinations with ultrasound, angiography, CT and MR angiography was defined. The definition of the radiation loading, which the patients from the collection during CT angiography were screened, followed. I also dealt with the estimate of the radiation loading of each patient during diagnostic angiography. Publications refering to this subject, the questionnaire, the data obtained from PACS and from the operation log of Nemocnice Na Homolce were the main sources to process the information. The method which is used the most frequently to diagnose aneurysmats abdominal aorta is CT angiography with the intravenous application of the contrast medium. Ultrasound is another significant method. It is clear from the questionnaire that responsibilities of radiographics are nearly the same at every working place. My work could be used as studying material for trainers.
