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.

Non-contrast MRI perfusion imaging
Kruml, Ondřej ; Jiřík, Radovan (referee) ; Krátká, Lucie (advisor)
This bachelor paper is focused on the magnetic resonance perfusion imaging technic without the usage of an external contrast media. This paper contains a look at the basic functional principle of the magnetic resonance. The focus is then set set on the Arterial Spin Labeling (ASL) technic. The basic principle of ASL uses protons from the water mocelules in arterial blood as an endogenous contrast agent. This technic can be used for obtaining a perfusion map of any tissue without the usage of invasiont echnics or contrast agents. The quantification of perusion was done applying the FAIR-RARE scheme, which belongs to the large family pulsed ASL.
