1. 1. Validation of Simultaneous T1 and T2 Mapping Using Cardiac Magnetic Resonance Fingerprinting in Self-Constructed Phantoms : An Analysis of the Reproducibility and Accuracy

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Sasithon Meesan; [2023]
   Keywords : Cardiac Magnetic Resonance Fingerprinting cMRF ; Cardiac Magnetic Resonance Imaging CMR ; Simultaneous T1 and T2 Mapping; Validation; Accuracy; Reproducibility; Cardiac Magnetic Resonance Fingerprinting cMRF ; Kardiovaskulär Magnetresonans CMR ; Simultant T1 och T2 Parametrisk-Karaktärisering; Validering; Noggrannhet; Reproducerbarhet;

   Abstract : Quantitative cardiac magnetic resonance imaging (CMR) has gained traction within both the clinical and research field due to high prevalence of cardiovascular diseases. Cardiac magnetic resonance fingerprinting (cMRF) is a novel approach introduced to address the limitation associated with evaluation of multiparametric quantitative CMR. READ MORE

3. 2. Optimization of MP2RAGE sequence parameters for head and neck T1-mapping and OE-MRI

   University essay from

   Author : Ellen Börjesson; [2022-05-04]
   Keywords : Medical physics; MRI; OE-MRI; MP2RAGE; T1-mapping;

   Abstract : Cancer is the collective name for more than 200 types of diseases that annually causes the death of 8.8 million people, cancer in the head and neck (H&N) accounts for 330.000 of these. It has been shown that hypoxic tumors are more resistant to treatment than well oxygenated tumors. READ MORE

4. 3. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Mustafa Kadhim; [2021]
   Keywords : Medicine and Health Sciences;

   Abstract : 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.

5. 4. Super-Resolution for Fast Multi-Contrast Magnetic Resonance Imaging

   University essay from Umeå universitet/Institutionen för fysik

   Author : Erik Nilsson; [2019]
   Keywords : Deep learning; convolutional neural networks; CNN; super-resolution; MRI;

   Abstract : There are many clinical situations where magnetic resonance imaging (MRI) is preferable over other imaging modalities, while the major disadvantage is the relatively long scan time. Due to limited resources, this means that not all patients can be offered an MRI scan, even though it could provide crucial information. READ MORE

6. 5. Regional MRI T1 mapping analysis of tobacco smoke exposed mouse lungs

   University essay from KTH/Fysik

   Author : Gustav Söderström; [2019]
   Keywords : MRI; Magnetic Resonance Imaging; Lungs; COPD; Chronic Obstructive Pulmonary Disease; T1 mapping; Tobacco smoke; Emphysema; Chronic Bronchitis;

   Abstract : Chronic obstructive pulmonary disease is the fourth largest cause of death worldwide and the prevalence is predicted to increase even further to make it the third largest cause of death by 2020. The main cause of the disease is exposure to tobacco smoke. READ MORE
