Imaging of the gastrointestinal tract - ERCP
 HROCHOVÁ, Simona
The bachelor thesis on GIT imaging methods with focus on ERCP deals with diagnostic and therapeutic methods and provides an overview of the individual imaging methods used in diagnostics and therapy. In the practical part, the thesis focuses on the ERCP diagnostic and therapeutic method. Knowledge of anatomy is indispensable for the orientation in this field and for the quality work of radiological assistants and physicians, and therefore the introduction is dedicated to GIT anatomy. Diagnostic procedures, including imaging methods, are described in each individual anatomical area, and the most common diseases affecting the indicated GIT area are listed. The second half of the theoretical part describes the diagnostic and therapeutic imaging methods of the digestive tract with respect to the anatomical area in which the examination is carried out, which fall under the X-ray unit and are performed by radiological assistants and doctors. The practical part is focused on the diagnostic and therapeutic method ERCP and its use at the RTG unit at Thomayerova hospital in the years 2014-18. The work covers the entire course of the examination from the preparation of the patient to the therapeutic procedures. A set of patients is used in terms of the frequency of the examinations carried out in 2014-18. In the individual years, patients are further broken down and analysed based on the decade of birth and gender. The data sets obtained are processed into clear graphs and the use of the method today is evaluated based on the proportion of patients undergoing the examination in the individual years using the date of birth and gender criteria. Specialized books and articles as well as verified internet sources were used to write this bachelor thesis. The results of my work give answers to the research question about the preferences of using the ERCP examination. They reflect the ongoing trend in the use of ERCP in diagnostics and especially in therapy due to the undeniable advantage of the use of therapeutic interventions immediately during the diagnostic examination. The aim of the thesis is to create a general overview and description of the individual methods of GIT examination according to the individual anatomical area with focus and a more detailed description of the ERCP method. An analysis of the data set obtained at the Thomayer Hospital's RTG unit was carried out.

Disturbing artifacts of radiodiagnostic modalities
 ŠEDA, Miroslav
This work gives information on machines used for diagnostic imaging aimed to disturbing scan artefacts of chosen device (CT, MR, USG). Radiology assistant work still more depends on technique which helps in examination. The machines used for clients´ examination are thanks to IT development still more complicated. They allow high-quality and precious images, give more possibilities of treatment ways, save the client. Operating this technique is the domain of radiology assistants. Development without restrain leads to period when operating staff will work more independently. It is necessary for the radiology assistant to manage all steps in examinations which are undergone. He has to keep radiation protection and the quality of the image result as well. The result of most diagnostic examination in radiology department is image information. Image results can be from various reasons changed or deformed in comparison with the reality. Such distorted images can lead up to mistaken or late diagnosis by the physician. Radiology assistant is the first specialist who must be able to judge whether the examination has been done correctly or to warn the physician of possible variation or image deformation. Moderation or suppression of artefacts in image results in examination is easy in some cases. Then it is enough to explain the process of examination to the client and to emphasize how important is to cooperate with the staff. In some cases is technically impossible to impact the manifestation of artefacts as it results from the principle of examination method, or because of high financial costs unbearable for the health institute. In my work I aimed to image artefacts of machines (CT, MR, USG) which can be met in common clinical practice. I tried to document these image artefacts in common running. Part of my work is to describe the causes of artefacts appearance and the way how to avoid or remove their manifestation.
