Katolický, Jakub ; Machač, Stanislav (advisor) ; Novák, Jakub (referee)
Diplomová práce Účinky rázové vlny v léčbě tendinopatie Achillovy šlachy 1 Abstract This thesis focuses on the observation of the effects of low-energetic focused extracorporeal shock wave therapy (ESWT) in the treatment of Achilles tendinopathy. The theoretical part summarizes the current knowledge of anatomical, histological, kinesiological and biomechanical aspects of Achilles tendon (AT), as well as pathological processes, which can be described as Achilles tendinopathy, their differential diagnosis and treatment options. Last but not least, we present up-to-date information on the physical principles and biological effects of ESWT, not only in the treatment of AT diseases. The main goal of our research was to determine the effectiveness of low-energetic focused ESWT in the treatment of Achilles tendinopathy in comparison to the placebo group. The subject of observation was not only changes in clinical manifestations, but also possible changes in the morphology of AT using ultrasonography (USG). Methods: A total of 20 patients with symptomatic Achilles tendinopathy was included in the study, while only 18 of them completed the entire program, and therefore only the results of these patients were evaluated. They were randomly divided into two groups in 1:1 ratio. Group A was treated by ESWT with...

CHARLES UNIVERSITY IN PRAGUE FACULTY OF PHYSICAL EDUCATION AND SPORT ADIPOSE TISSUE DISTRIBUTION BY PRESCHOOL CHILDREN- COMAPARATIVE STUDY ABSTRACT Head of the dissertation: Author: Prof. MUDr. Ivan Dylevský, DrSc. Mgr. Dominika Petrů Prague, 2014 Abstract The dissertation provides information about the distribution of subcutaneous adipose tissue in preschool-aged /5-6 years, n=141/ and younger school-aged children /8- 9 years, n=137/ in the Ústí region. In this review, we describe and evaluate the child's body with anthropometric parameters, skinfold, bioelectrical impedance analysis and selected sample /n=31/ with ultrasonography. We found an increased distribution of adipose tissue in older file with a concentration in the abdominal area and a higher reliability of skinfold than the BIA, considering the ultrasound examination. Key words: subcutaneous fat, skinfold, bioelectrical impedance analysis, ultrasonography

Computer analysis of ultrasound images of thyroid nodules, focusing on their sonographic features and cytological findings.
Procházka, Antonín ; Smutek, Daniel (advisor) ; Rožánek, Martin (referee) ; Jiskra, Jan (referee)
Ultrasound imaging is one of the fundamental examinations of thyroid nodules, determining whether a patient undergoes a cytological examination, which is essential for the decision on a possible thyroid surgery. Unfortunately, the cytological examination has limited specificity and potential surgery carries risks. Therefore, other diagnostic methods are being sought with hope that they will be able to bring more certainty into diagnostics. One of the new methods is computer-aided diagnosis (CAD), which exhibits promising results using image analysis and machine learning. In this study, we present two somewhat similar, yet different, CAD approaches. The first approach is based on analysing entire nodules using a Segmentation Based Fractal Texture Analysis (SFTA) algorithm that splits the image into individual grayscale bands. Using this approach, we have achieved an accuracy of 92.4% using random forests (RF) and 95% using support vector machines (SVM) on a data set of 40 images evaluated by the cross-validation method. The second CAD approach is also based on the method of multiple image thresholding, but the difference is, that a larger number of predictors describing the binary texture are extracted from the individual grayscale bands. Furthermore, the analysis did not take place on whole nodules, but on...

Use the Contrast-Enhanced Ultrasoun in the Morning of the Effect of Liver Tumors Treatment by Radiofrequency ablation
Korčáková, Eva ; Mírka, Hynek (advisor) ; Mechl, Marek (referee) ; Čtvrtlík, Filip (referee)
Use the contrast-enhanced ultrasound in the monitoring of the effect of liver tumors treatment by radiofrequency ablation. Summary High quality imaging is crucial for the treatment of liver tumors by the percutaneous radiofrequency ablation. Imaging methods are used for planning, navigation of the intervention and monitoring after treatment. An early detection of residual tumor tissue or recurrence affect significantly the quality of life and life expectancy of the patients. Contrast enhanced ultrasound (CEUS) seems to be a suitable method for monitoring the locoregional treatment mainly because zero radiation impact on patient and allows the highly accurate real-time assessment of vascularization. The aim of my work was to verify the ability of CEUS to detect residual tumor tissue or tumor recurrence in the field of changes after radiofrequency ablation. We evaluated the group of 73 patients, who were treated by radiofrequency ablation (RFA) for liver cancer. CEUS reached in our group the overal sensitivity 77.27 %, and in the group of colorectal cancer metastases 83.33 %. We compared CEUS with results of computed tomography (CT), which is the most commonly used method for monitoring the treatment. CEUS and CT results are similar. Based on this study, the CEUS appears to be a suitable method for monitoring...

Markers of joint inflammation related to disease activity in rheumatoid arthritis.
Hurňáková, Jana ; Pavelka, Karel (advisor) ; Horák, Pavel (referee) ; Hrnčíř, Zbyněk (referee)
Background: Rheumatoid arthritis (RA) is a common chronic autoimmune disorder characterised by persistent synovitis, typically manifested as symmetric polyarthritis of small hand joints with various extra-articular manifestations. Accurate disease activity measurement is a key component of RA management that facilitates therapeutic optimalization in order to slow down the disease progression and to prevent an irreversible joint damage. The aim of this work was to study the role of candidate serum inflammatory markers and their associations with the disease activity in patients with RA presented by traditional variables of disease activity as well as by musculoskeletal ultrasonography. Results: The first part of our work pointed out relationship between serum calprotectin and clinical as well as ultrasound activity in RA. We have revealed that serum calprotectin is an independent predictor of ultrasound synovitis. Moreover, we have demonstrated the potential of calprotectin to identify patients with residual activity in spite of achieving clinical remission. In the second part, we have provided a detailed analysis of 20 candidate serum markers and found out a tight associations between IL-6, IL-7, IL-22, IL-34, YKL-40, CXCL-13, MMP-3, resistin and visfatin with clinical and ultrasound activity....
