Analysis of brain tumors based on line of interest
Širůčková, K. ; Solár, P. ; Marcoň, P.
Due to the high resolution of soft tissue, magnetic resonance imaging plays a crucial role in the diagnosis and therapy planning in the neurosurgery field whereas it is necessary to determine which pathology in the brain tissue is involved. Glioblastoma multiforme, metastatic tumors and abscesses are examined in detail from magnetic resonance images. In clinical practice, all mentioned pathologies are diagnosed through invasive methods in the form of biopsy followed by histology of the affected tissue. This work is focused on an alternative non-invasive method of tumor diagnosis. The method is based on the data analysis from defined curves (drawn into the apparent diffusion images) that lead from the tumor area. The analysis of curves could lead to non-invasive diagnostics of the pathological tissue.

The Role of Imaging in Surgical Inflammatory Complications
KOPRDOVÁ, Eliška
The Role of Imaging in Surgical Inflammatory Complications Interventional radiology is a dynamic and fast developing specialization. Development of new methods and instruments extends possibilities of mini-invasive treatment of a wide range of illnesses. Introduction of a specific percutaneous drain in case of abdominal abscess in clinical practice counts among most important progress of 1980s concerning this field. The percutaneous drain is relatively fast and simple method and it belongs to urgent interventional operations. Indication for the percutaneous drain is a treatment or a palliative treatment of sepsis accompanied by an infected lesion. Most authors agree that there is no absolute contraindication of the percutaneous drain for pathological liquid collection. Therefore, this type of drain may be considered as a method selection. It is possible to execute it even before a possible surgical operation. The goal of my work was to assess retrospectively the experience of the Radiological Department of the Teaching Hospital in Plzeň Bory concerning this field within the selected period of time. For this reason, a single-purpose database has been created, which contains data of patients who underwent the percutaneous drain under the supervision of the CT or UZ within a certain period of time. Such data has been processed statistically. The work did not prove any of the hypotheses of mine that interventional techniques may in all cases substitute surgical operation while treating suppurative inflammatory lesions in the area of chest, abdomen and soft tissues. The percutaneous drain brings unquestionable advantages into clinical practice. Among most important ones, there are a removal of a surgical operation risk and of total anaesthesia, above all in the acute phase of illness. Simplification of post-operative care, shortening of the average hospitalization as well as economic advantages. This concerns a method that should always be considered as the first step among possible treatments of infected lesion.
