Arterial Spin Labeling MRI Data Analyzation
Galanová, Zuzana ; Jiřík, Radovan (referee) ; Krátká, Lucie (advisor)
This bachelor´s thesis is focusing mostly on perfusion imagining, which is done by the method of arterial spin labeling. It describes physical basics of nuclear magnetic resonance, image reconstruction, perfusion imagining without contrast substances, principles of arterial spin labeling and different ways of arterial spin labeling – mostly FAIR-RARE sequence, which belongs to the pulsed arterial spin labeling. One part of the thesis is dedicated to production of perfusion map in Matlab. Results are evaluated by comparison of data produced in Matlab and data produced in Paravision Version 5.1 and they are discussed.

Quantification of Perfusion using MRI ASL Methods
Kolajová, Martina ; Mézl, Martin (referee) ; Jiřík, Radovan (advisor)
This bachelor thesis deals with quantification of perfusion using a contrast-free MRI technique called „Arterial Spin Labeling“ (ASL). Firstly, the physical principle of magnetic resonance imaging and the concept of perfusion will be described for better understanding of the subject. The next chapters will focus on the ASL method itself and perfusion quantification using mathematical models, namely T1 perfusion and Standard. The algorithm for preprocessing and analysis of selected datasets, designed in the thesis, is implemented using the program MATLAB. Program BASIL was used for further processing. The outputs in the form of perfusion and ATT maps and model fitting processes using various models from both programs are compared and evaluated.
