Development of algorithm of imaging methods in diagnostic of knee joint in years 2001 - 2006 in University Hospital Motol
REDLICH, Peter
Knee joint is the biggest and the most complex joint of moving system. Its exceptionality embodies in difficult anatomical structure and static-dynamic function. Elongated human life and increased moving and sport activities lead to higher risk of knee joint injury. In monitored period (2001 {--} 2006), imaging methods of knee joint examinations experienced immense development which would continue in near future. Native skiagraphic examinations remain an inseparable part of algorithm of imaging methods. Though, methods without the use of ionizing radiation: magnetic resonance and ultrasound gain ground. In monitored period, the number of examinations with magnetic resonance markedly increased and continuation of this trend can be expected. That is especially because this method is noninvasive and the diagnostic yield is considerable. In 2001 to 2006, there were carried out totally 35 691 knee examinations for 23 602 667 points at total rate 21 006 565 Kč. Total number of native skiagraphic examinations is almost the same. I noted forceful growth of magnetic resonance examination in 2003 {--} 2006.The numbers of other examinations are without expressive changes. The total price of separate examinations is relatively the same but the total price of magnetic resonance examination is thanks to increasing number of examinations quite high. The results showed that despite of increasing number of magnetic resonance examinations, corresponding decrease of ionizing radiation examination doesn´t happen.

Demands on radiology assistants at three-dimension visualization
ČECH, Svatopluk
Fast development of three-dimension visualization in radiology relates to more sophisticated diagnostic machines, with the development of computer technology and digitizing. Increasing demands on radiology assistants in operating programs of reconstruction images increase the importance of their position at modern radiology workplace. Three-dimension images offer exact and undistorted images of patient's anatomy, they give better diagnostic information for physicians - radiologists and more objective imagination for physicians - clinicians. They find the application in a number of examinations in skiagraphy, angiography, computer tomography, magnetic resonance and ultrasonography. We can say that three-dimension visualization substitutes other examination which are invasive and represent certain complications for a patient. The question is whether some three-dimension examination can reduce radiation load of a patient. We can suppose that digital imaging methods will be part of near future and three-dimension visualization and further development of computer technique will acquire still more impact in diagnostic of many diseases.

Present possibilities of using X-ray technology for examination of urology diseases
PODEŠVOVÁ, Jitka
Imaging methods play an essential role in the diagnostic algorithm by determining the disease character in any part of the human body. The same applies to uroradiology where we use both standard methods and recent modalities. In the opening part this theses I mention anatomical and physiological aspects of the urinary tract and describe conventional radiology methods, digitally processible (ultasonography, computer tomography, megnetic resonance) and interventional. Individual examination methods contain comments related to indication and contra-indication when applying a contrast agent and how to prevent allergic reactions, or possibly how to mange them if they have already occurred. In the following part of thesis I try to describe and evaluate costs of each examination. After a brief summary of radiating load in radiology methods I try to work out statistically a patient file examined on x-ray department in the Krnov´s hospital in October and November 2006 where I monitored whether urologists observe the algorithm of examination methods at patients with urological diseases.

Conventional imaging procedure in radiology with a view to urogenital system (the education programe)
DVOŘÁČEK, Petr
In my work I concentrate on the basic examination methods for the urogenital system. It is about excretory urology (VUG), cystograph, cystouretrograph, retrograde uretrograph (ascending), histerosalpingograph (HSG), retrograde (ascending) pyelograph and antigrade (descending) pyelograph. Very detailed I describe the indication, the preparation and the follow through of the examinations. I am trying to compare non-invasive and invasive methods in the diagnosing of the urogenital system. I use the statistics of chosen hospitals in south of Czech Republic area in the time-span between 2000 and 2006. The modern radiodiagnostics methods together with the non-invasive and invasive methods in the diagnosing of the urogenital system still have non replaceable meaning in algorithm of the examinations in the urogenital system.

Volumetric model of human vocal folds
Vampola, T. ; Horáček, Jaromír
The article describes the vollumetric 3D FE model of real human vocal folds in a defined phonation position. The model was developed from the CT images of the plaster casts obtained by a special procedure during experiments with the excised human larynges, when the phonatioon caused by the airflow was suddenly stopped without changing the position of the fixed larynx. The model is determined for studies of dynamical stresses in the vocal fold tissue during vocal folds collisions.
