Due to the high signal intensity of cerebrospinal fluid (CSF), proton density-weighted (PD-w) images with long repeat times (TR) may be less able to detect periventricular lesions in patients with multiple sclerosis (MS). However, we have found good detectability of MS lesions with PD-w us...

High-field MRI studies have shown that penetrating veins can be detected in most MS lesions using T2∗weighted or susceptibility-weighted imaging. Future studies must address the feasibility of imaging such veins in a clinically practical context. The specificity of this biomarker has been studied ...

We investigated 45 patients with focal hepatic lesions. T 1 -weighted SE (TR 650/TE 15 ms) and T 2 -weighted SE (TR 2015–2030/TE 45 and 90 ms) unenhanced images were obtained. After SPIO application we performed T 1 -weighted images with and T 2 -weighted images with and without...
The detection of more lesions at high-field strength did not seem to lead to earlier diagnosis of clinically definite multiple sclerosis. Further larger studies of patients with clinically isolated syndromes are needed to settle the question of a diagnostic consequence of high-field imaging in MS. ...
PURPOSE Conventional T1 and T2 MRI are not consistently specific and sensitive for the detection of early articular cartilage lesions seen with OA. The objective of this study was to test the hypothesis that chondromalacia observed during arthroscopy correlates with changes observed in T1ρ MRI. METHO...

Correlating MRI and clinical disease activity in multiple sclerosis: relevance of hypointense lesions on short-TR/short-TE (T1-weighted) spin-echo images Magnetic resonance imaging (MRI) is being used as an outcome criterion in therapeutic trials in multiple sclerosis (MS) on the assumption that ...
q-Space Novelty Detection with Variational Autoencoders We apply these methods to magnetic resonance imaging, namely to the detection of diffusion-space (q-space) abnormalities in diffusion MRI scans of multiple sclerosis patients, i.e. to detect multiple sclerosis lesions without using any ... A...
