Bajcurová, Kristýna ; Mírka, Hynek (advisor) ; Weichet, Jiří (referee) ; Mechl, Marek (referee)
Objective: The possibilities of CT examinations in patients with multiple trauma are: two- phase, or single-phase CT examination. However, a single-phase contrast medium (CM) administration doesn't suffice quality saturation of arteries along with parenchymal organs. My dissertation is focused on a split-bolus contrast medium administration technique. Aim: To prove diagnostic quality of protocols using split-bolus technique. Materials and Methods: Patients were divided into eight groups, namely A to H. After the non-contrast examination of the head and the cervical spine, all patients were examined after CM administration from the skull base to the symphysis. Group A patients underwent a biphasic examination after CM single-bolus, group B patients underwent single-phase examination after a single bolus of CM, and group C-H patients underwent a single-phase examination after split- bolus technique of CM administration. Patients were given 100 ml of CM at the same concentration of 350 mgI/ml. The densities variables in internal carotid arteries, aorta arch, abdominal aorta, common pelvis arteries, liver, v. portae, spleen and kidney were evaluated. The Krusakal-Wallis ANOVA nonparametric statistical method was used to evaluate the variables. The abnormal distribution was found using the Saphiro-Wilk...
