PURPOSE T1WI (T1 weighted image) was acquired in order to grade bone fusion following the studies by FIFA (Federation Internationale de Football Associations). Research using images other than T1WI has not been reported. The aim of this study is to evaluate the grade of epiphyseal fusion by T2* weighted images (T2*WI) and to investigate new findings on T2*WI as compared with T1WI. METHODS A t...

Background Previous studies observed the phenomenon of high signal intensity on T2 -weighted image of cardiac magnetic resonance imaging (CMR) in hypertrophic cardiomyopathy (HCM). However, the underlying histopathologic mechanism is unclear. Elevated cardiac troponin can be detected in some HCM patients. A reasonable hypothesis is that myocardial T2-high signals is a potential marker of myocar...

BACKGROUND T2-Weighted MRI reveals myocardial edema and enables estimation of the ischemic area at risk and myocardial salvage in patients with acute myocardial infarction (MI). We compared the diagnostic accuracy of a new bright-blood T2-weighted with a standard black blood T2-weighted MRI in patients with acute MI. METHODS AND RESULTS A breath-hold, bright-blood T2-weighted, Acquisition for...

  Background: Intervertebral disc herniation has two common types, extrusion and protrusion, which may affect the adjacent vertebrae.In addition, it is associated with significant signal changes in T1 MRI (short TR/TE) and T2 MRI (long TR/TE).   Methods: The present study is a cross-sectional analytic one, in which sampling was performed retrospectively. Cases were randomly selected from the pa...

INTRODUCTION One leading hypothesis suggests that schizophrenia (SZ) is a neurodevelopmental disorder caused by genetic defects in association with environmental risk factors that affect synapse and myelin formation. Recent magnetic resonance imaging (MRI) studies of SZ brain showed both gray matter (GM) reduction and white matter (WM) fractional anisotropy reduction. In this study, we used T1-...

OBJECTIVE The purpose of this study was to evaluate the effectiveness of the periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER [BLADE in the MR systems from Siemens Medical Solutions]) with a respiratory compensation technique for motion correction, image noise reduction, improved sharpness of liver edge, and image quality of the upper abdomen. SUBJECTS A...

PURPOSE To retrospectively determine the additional value of diffusion-weighted magnetic resonance imaging (MRI) to T2-weighted imaging in the evaluation of anal fistulae in comparison with gadolinium (Gd)-enhanced imaging. MATERIALS AND METHODS Thirteen patients (mean age, 35.2 years) with 20 anal fistulae were included. The protocol consisted of fat-suppressed T2-weighted fast spin-echo, di...

Introduction Vessel wall MRI has emerged as a powerful tool for assessing therapeutic response in atherosclerotic disease. Human studies involving the carotid artery have shown that lipid lowering therapy leads to regression of overall carotid plaque burden [1], and reduction of necrotic core components within the plaque [2-3]. These approaches, however, have some drawbacks. Assessment of plaqu...

PURPOSE To develop an image analysis technique that distinguishes pseudoprogression from true progression by analyzing tumour heterogeneity in T2-weighted images using topological descriptors of image heterogeneity called Minkowski functionals (MFs). METHODS Using a retrospective patient cohort (n = 50), and blinded to treatment response outcome, unsupervised feature estimation was performed ...

OBJECTIVES Multiple sclerosis lesions appear as areas of high signal on T2 weighted MRI. A proportion of these lesions, when viewed on T1 weighted MRI, appear hypointense compared with surrounding white matter. These hypointense T1 lesions are thought to represent areas of greater tissue damage compared with the more non-specific, total T2 lesion load. This study aimed to better characterise th...
