1. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction: The MP2RAGE technique has become popular for structural MRI at ultra-high fields. The core idea behind MP2RAGE is to reduce the influence of flip angle inhomogeneity (B +), proton density and T2* by calculating the regularized signed ratio of two complex MP-RAGE images acquired at different inversion times (TI) within the cycle.

2. Real-time imaging of cerebrospinal fluid flow physiology at 7T
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background The cerebrospinal fluid (CSF) is involved in several diseases and patho- physiological states, such as Alzheimer’s disease and hydrocephalus. Previous studies CSF dynamics in the brain show that the flow of the CSF depends on cardiac pulsation, time of day and respiration. READ MORE

3. Quantification of Fatty Acid Composition Using MRI: Comparison of Accuracy at 1.5, 3 and 7 T
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : The increasing prevalence of obesity and obesity related diseases in this modern world has resulted in a lot of research in the area of water-fat separation with magnetic resonance imaging (MRI). Since the introduction of the two-point Dixon technique, this area of research has expanded and relationships have been discovered between fat content and fatty acid (FA) composition, and diseases such as diabetes and non-alcoholic fatty liver disease.
