Development and Application of Magnetic Resonance Imaging Techniques for the Study of Exercise-Induced Angiogenesis in the Rat Brain
… To accomplish this, we have performed functional imaging experiments in groups of rats allowed either to exercise or remain inactive for a thirty-day period. We have looked at changes in the local deoxyhemoglobin concentrations using T2*-weighted imaging, changes in blood flow, and changes in …

Acquisition and reconstruction techniques for improving rapid magnetic resonance imaging with applications in fetal imaging
Magnetic Resonance Imaging (MRI) serves as a powerful and noninvasive medical imaging modality. It gives clinicians the ability to image a wide variety of physical parameters, control image content, and acquire images at arbitrary spatial orientations and resolutions. Recently, MRI has gained …

Radiofrequency Lesion Assessment by Cardiac Magnetic Resonance Imaging following Atrial Fibrillation Catheter Ablation
… using MRI with gadolinium delayed enhanced (DE) imaging and high signal T2 weighted imaging. Levels of DE and T2 were low in pre-procedural scans but rose dramatically immediately following the procedure. Acute DE was greater in patients without recurrences compared to those with recurrences. …

Functional Imaging to enable more accurate localisation and characterisation of prostate tumours
… Therefore, the development of non-invasive imaging methods to stratify prostate cancer is important for patient management. Recently, multiparametric MRI has revolutionised the work-up of prostate cancer, becoming a routine part of clinical practice and migrating earlier in the diagnostic …

Detection of prostate cancer using multi-parametric magnetic resonance
… information from 3 different MR methodologies: T2-weighted, T2-mapping, and Line Scan Diffusion lmaging(LSDI). From these MR sequences, 4 sets of image intensities were obtained: T2-weighted(T2W) from T2-weighted imaging, Apparent Diffusion Coefficient(ADC) from LSDI, and Proton Density (PD) and …

Magnetic resonance elastography studies of human skeletal muscle
… until the advent of a new Magnetic Resonance Imaging (MRI) technique known as Magnetic Resonance Elastography (MRE). MRE is a phase-contrast imaging technique that enables quantification of tissue mechanical properties by capturing the motion of induced shear waves via a synchronised Motion …

Cardiac sarcoidosis defined by cardiovascular magnetic resonance: patient characteristics and outcomes
… had evidence of acute myocardial oedema on T2-weighted imaging and T2 mapping, and 91% of subjects had evidence of focal fibrosis/infiltration on late gadolinium enhancement (LGE). Most patients (80%) had normal pericardial thickness and small pericardial effusions (< 1 cm) were noted in …

Improving Quality of Prostate MRI
… adopted international guidelines, Prostate Imaging Reporting and Data System (PI-RADS). Furthermore, image quality is fundamental to prostate MRI, as it impacts nearly every subsequent step in patient management, including biopsy, treatment, and surveillance. Therefore, Chapter 1 concluded …

Quantitative and Qualitative Assessment of the Myocardium at Risk
… provided treatment. Cardiac magnetic resonance imaging (CMR) has the opportunity to accurately assess both the myocardium at risk as well as the infarct size. This thesis has contributed to the knowledge on quantification of the myocardium at risk and subsequently myocardial salvage with the use …
