The role of radiology in children hip screening in Pelhřimov Hospital, c. o.
CHADIMOVÁ, Jana
The topic of this thesis is to compare the use of imaging methods in children hip screening and to find out the presence of developmental dysplasia of the hip (DDH) in Pelhřimov Hospital. DDH is the most common musculoskeletal developmental defect which affects approximately 5% of newborns. It includes an impaired development of acetabulum, femoral head, poor centering into the acetabulum or disproportionate extent of joint movement. DDH is being formed by interaction of genetic factors and external causes. If DDH occurs in the family, the risk neonate increases significantly. The most serious stage of this defect is hip dislocation, but we often meet a lighter form of this defect, which is called shallow acetabulum. The Czech Republic established a system of consecutive check-ups of neonates and infants. It was created on the base of Methodological Sheet of the Ministry of Health from 1996. These examinations are carried out in three stages. During these examinations, ultrasound plays a very important role. The most common method, also used in Pelhřimov Hospital, is the method of Austrian professor Graf. This method evaluates findings and classifies them into groups. After the first year of age, when ossification of structures is nearly completed, the findings cannot be evaluated by this method. X-ray examination is applied in case of diagnostic uncertainties - especially when planning subsequent treatment in children with DDH diagnosis. Imaging methods are applied to determine anatomical reposition obstacles after an unsuccessful primary reposition. We can use ultrasound, magnetic resonance, but we prefer arthrography. Arthrography is more invasive method, but unlike the others, it has got an important advantage: it can also be a therapeutic method. The theoretical part deals with anatomy, development and growth of the hip joint. I also present etiology and history of this developmental defect. The following part deals with a description of the system of clinical check-ups and diagnostics of DDH. Another part of the theoretical work is devoted to individual imaging modalities - ultrasound, X-ray, magnetic resonance and arthrography. Imaging modalities are a very specific part of radiodiagnostic. Paediatric patients are not small adults, their imaging should be restricted to a minimum and it has got its own specifics. The examination must be performed quickly and accurately, in order not to have to be repeated. Options of therapy varies according to the severity of the hip joint. A small damage of the hip joint is solved by a conservative way using various abduction tools like abduction package, Frejk duvet or Pavlík calipers. More serious cases need to be solved by hospitalization, using distraction therapy or surgery. The aim of this work was to analyze the number of paediatric patients, to find out what kind of imaging methods were indicated and performed and to compare the presence of congenital defect of the hip according to sex within Pelhřimov Hospital. The hypothesis of this thesis was formulated as follows: In paediatric hip screening examination in Pelhřimov Hospital presence of congenital defect of the hip is higher in girls than in boys. The purpose of this thesis was to create a comprehensive text dealing with the use of imaging methods in detecting developmental defects of paediatric hip. The theoretical part of this work may serve as information material for professionals and the results can be used as statistical material.

Radiographer role in non-vascular intervention procedures and their frequency at Imaging clinic of Faculty Hospital Motol in years 2008 - 2013.
BOROVCOVÁ, Veronika
This bachelor thesis focuses on non-vascular interventions, which are carried out at the Imaging clinic of Faculty Hospital Motol. The area of interest was fixed to the adult part of this clinic. The most frequently performed interventions were described and for aech of these examinations was depicted the role of radiographer (patient preparation, sterila table and instrumentation preparation) and it´s operating procedures. The other part of the thesis pays atention to statistical analysis of the frequency of individual most often led examinations. The statistical overview was done by using tables but also graphs. The examinations are devided according to their modalities based on where they were ran. This division was left for statistical part, as well. The period of time, which was trailed in this thesis makes 6 years, since 2008 to 2013. The obtained data displays the individual frequency of interventions and covers complete overview in mentioned issue.

Special access of the radiology assistant to interventional procedures in diagnostics of oncological patients
CANDROVÁ, Daniela
In my work I deal with the peculiarities in approach of a radiology assistant to interventions in diagnostics of oncological patients. Biopsy has a special importance in diagnostics of neoplasm. It is essential for histological and cytological diagnostics. The aim of this work was to find out the incidence of bioptic interventions on oncological patients during one year at radiology department at České Budějovice hospital plc, and to compare the advantages and disadvantages of used modalities. The work proceeds from the presumption that the number of interventions carried out under the sight control without the use of ionizing radiation methods is growing. In the theoretical part of my work appear descriptions of bioptic methods of intervention radiology regarding oncology and its methods, biopsies, screening methods used at biopsy (ultrasound controlled biopsy, computer tomography controlled biopsy, magnetic resonance controlled biopsy, skiascopic controlled biopsy), instrumentarium, especially the needles used for tissue extraction (puncture and bioptic needles), characteristics of oncological patients, the principle of tumour disease, carcinogenesis, oncologically changed tissue, and basic diagnostics of oncology disease. The practical part reveals the number of biopsies performed in 2012 at České Budějovice hospital plc, under computer tomography, ultrasound and mammography machine control, and the number of other interventions on oncological patients, namely localization of impalpable breast lesion, percutaneous drainage of the urinary tract under skiascopic control. Standard methods regarding these interventions and biopsies are described focusing on the advantages and disadvantages of their use for different organs in the body. I also described radiology assistant?s work and created photo documentation of given interventions. In 2012, 96 biopsies were performed under any of the mentioned diagnostic screening methods at radiology department of České Budějovice hospital. They represent 0,06% of the total of 171 466 diagnostic interventions at this department in the respective year. At the same time they represent 3,4% of the total of 2844 interventions of the ČB radiodiagnostic department of that period. From the whole number of 96 biopsies, 79% were performed on oncological patients. No biopsies were performed under magnetic resonance or skiascopic- skiagraphic control. Since the formation of a tumour is supposed to be the main somatic risk which an individual after a low intensity radiation faces, I supposed that the number of bioptic samples taken under sight control without the use of non ionizing radiation is rising, which significantly contributes to radiation protection. It is not univocally assigned which screening method is the best for biopsy. Usually we chose the biopsy that can screen best the site in different organs and that allows the safest, the fastest and the economically most convenient procedure. The chosen method should allow the doctor chose the site for sample extraction. The choice also depends on the habits and the technical equipment of given hospital. In view of the fact that according to this work computer tomography is the most commonly used method for bioptic extractions, and under magnetic resonance control no biopsies are performed, the prestige and importance of a radiology assistant grows up, because their presence at modalities using ionizing radiation is commonly indispensable. The hypothesis of my work has not been proved. Concrete results do not support the operative hypothesis of y work. However, I can recommend concessive long-term type and multicentrically elaborated sample studies. I would be grateful if this work provided an information base for radiology assistants´ training and for interventions in the diagnostics of oncologically ill people.
