The role of radiology assistant by fluoroscopic examination of gastrointestinal tract
REMTOVÁ, Barbora
I focus on working methods of radiologist assistants in various types of examinations of gastrointestinal tract in my thesis. The number of gastrointestinal tract has increased. In latest ten years the number of colorectal carcinomas has been rising, with women in particular, and carcinomas of liver with men. The Czech Republic dominates Europe considering the occurrence of colorectal carcinomas. Therefore these types of examinations have been indicated more and more often. When the carcinoma is found out in an early stage there is a chance of recovery almost for 95% patients. Radiodiagnostic methods are a contribution not only in finding carcinomas, but also in other diseases of GIT. The number of sciascopic method examinations decreases, but still they have their important place in radiodiagnostics. The goal of my work is to show radiodiagnostic methods, such as X-ray, computed tomography, sonography and magnetic resonance. Next I describe in details methods in sciascopic examination and computer tomography. Each of these examinations was described in a single chapter. I describe the task of radiologist assistant at these examinations when his/her presence is necessary. Radiologist assistant is a medical worker working on the departments of radiology, radiotherapy and nuclear medicine. During recent years a system of radiologist education has principally changed. It is newly founded on university education. His/her competencies are: to perform the tests of operating stability, to ensure so that the medical radiation were in accordance with principles of radiation protection; to provide nursing care at radiological procedures; to perform sciagraphic procedures and preoperative sciascopy; to perform radiologic imaging procedures at medical radiation; to assist at intervention radiology; to perform therapeutic radiation procedures. Besides other things a radiologist assistant is required to know the anatomy of a human body on well. That is the reason I present a detailed anatomy of gastrointestinal tract in my work. I also present diseases of single parts of GIT, where radiodiagnostic methods are especially used. The goal of the second part is to give a detailed idea of radiologist assistant work on a radiodiagnostic ward CT and sciascopic ward. I used professional literature and questionnaire method for this purpose. The questionnaires were distributed to radiologist assistants working in researched departments. These questionnares were used for answering the research question whether the task of radiologist assistant is less demanding and shorter in time with CT examinations of GIT than with sciascopic examinations. In the chapter Results I described sciascopic methods and CT examinations of GIT. I also described the work of a radiologist assistant and evaluated answers of questioned radiologist assistants. I compared these results with the available professional literature of older and recent issues in the chapter Discussion. The results confirm the asked researched question that the assistance at CT examination is less demanding and shorter in time than at sciascopic methods and comparing to older issues of professional literature we cannot find any significant progress in sciascopic methods. The professional literature from the end of the 20th century describes sciascopic methods and work of radiologist assistants the same way as today is. CT methods were in a developing phase and were improved. The professional literature does not present exact procedures for examinations, therefore the described work of a radiologist assistant at a CT examination is inspired by personal experience from the practice in this branch.
