CT and MR and their mutual use in diagnostics
KOCHWASSER, Jiří
This bachelor thesis deals with computed tomography and magnetic resonance imaging and their mutual use in diagnostics. Computed tomography and magnetic resonance imaging are an integral part of modern radiology and play an essential role in the accurate diagnosis of many diseases. In this field, quality and modern instrumentation and a professional approach of the medical staff performing the examinations are important. In the first, theoretical part, the physical principles of computed tomography and magnetic resonance imaging, their history and their characterictis are described in detail. The theoretical part is compiled from the specialised literature, both printed and published on the Internet and is prepared in the form of a search. This thesis aims to describe the detailed physical principles of both diagnostic methods, to analyse the applicability of these imaging methods in hospitals and to analyse the mutual use of computed tomography and magnetic resonance imaging. The thesis is designed as a comrehensive review concerning the use and operations of CT and MRI imaging methods. To meet the objectives and research questions, we used annual reports, from 2012 to 2021, on the instrumentation of healthcare facilities from the Institute of Health Information and Statics of the Czech Republic (IHIS), which are provided under the Ministry of Health´s Statistical Survey Programme. This objective was supported by the research question: What is the most common use of CT and MRI in the algorithm of medical imaging examinations?

Physics problems for radiology assistants
KOVÁŘ, Jan
The thesis was examining an opportunity to apply the curriculum process theorem in the matter of general and radiology physics and their problems' expression. The first objective is to create an educational text which would elucidate an indispensable theory for radiology assistant. The educational text is to involve problem expressions of needful physical fields. The second objective was to implement the curriculum process as a quiz and so to evaluate the familiarity among the professionals in the field. Furthermore, three hypotheses were formed. The first hypothesis presumed it is possible by applying the curriculum process to delimit the collection of physics problems that will be tailored to the needs and facilities of radiology assistants. The second hypothesis was divided into two subparts: A) By comparison of a physics structure and compounds of a radiology assistant profile it is possible to process a collection of problems dedicated to general physics. B) By comparison of a physics structure and compounds of a radiology assistant profile it is possible to process the collection of problems dedicated to radiology physics. The third formed hypothesis presumed the familiarity among responders regarding the field will resemble of normal distribution. By comparing the conceptual curriculum of physics and radiology, an educational text was created, which contained exemplary statements of general and radiological physics in relation to the components of the profile of the radiological assistant. By creating the text and defining example statements, the first goal of the work was fulfilled, and the first two hypotheses were accepted. Another application of the curricular process was to compile a test, the questions of which were based on the content of the educational text. Descriptive and mathematical statistics were used to appraise the research observing the test results. The outcome of the research acknowledged the third hypothesis. The second objective was reached by the test implementation. As a certain standardisation the second, previously used test was handed to the responders concomitantly to the first test. Via a parametric test the link between both tests results was confirmed. Following correlation analysis established the strong positive correlation. The results of the bachelor's thesis show that the created educational text together with a set of example statements can be effectively used to prepare students for the profession of radiological assistant.

Retrograde study of the effect of the shock ware therapy for the functional disorders of the musculosceletal system
Horáková, Kateřina ; Doubková, Lucie (advisor) ; Veselá, Jana (referee)
This thesis assesses the effectiveness of shock wave therapy for dysfunctional disorders of the musculoskeletal system. While we are well aware of the physical principles and history of shock wave generators, opinion differs on the treatment effectiveness mechanisms. The theoretical part of this work explains the effects of shock waves on various types of tissue, the differentiation of the cells, and the analgetic effect of therapy. It summarizes the indications, side effects and contraindications of shock wave therapy. The research part of this thesis deals with the effectiveness of shock wave therapy at the Department of Rehabilitation and Sports Medicine at the Motol University Hospital, which specialises in various musculoskeletal disorders. This thesis evaluates the correlation between the effectiveness of shock wave therapy and length of time the patient has experienced difficulties before undergoing treatment. This thesis also reviews whether the number of treatment applications has the capability to influence the outcome of therapy. The study is controlled by a control group of 22 patients. The total effectiveness of shock wave therapy is p = 1,12*10-10 . The shock wave therapy effectiveness of patients with heel spur is p = 0,00176. The shock wave therapy effectiveness of patients with...
