Multi-contrast MRINeuroMixIschemic strokeDiagnostic performancePurpose To assess the performance of a 2.5-minute multi-contrast brain MRI sequence (NeuroMix) in diagnosing acute cerebral infarctions.Methods Adult patients with a clinical suspicion of acute ischemic stroke were retrospectively included. ...
By increasing the contrast of an image, it will be easy for analysing because of detailed information. This increase in contrast can be done by number of ways in image processing. This paper compares different methods of enhancement of brain MRI using histogram based techniques. 展开 ...
Our purpose was to compare prospectively the sensitivity of contrast-enhanced magnetisation transfer (MT) MRI and gradient-echo (GE) T1-weighted images in metastatic disease of the brain. We studied 52 patients with brain metastases, using conventional T1-weighted GE and MT spin-echo (SE) images...
INTRODUCTION: The aim of this study is to investigate perfusion characteristics of brain arteriovenous malformation (AVM) by means of MRI perfusion-weighted imaging (PWI). METHODS: Forty-three patients with brain AVM were prospectively included and investigated by PWI-MRI. Diagnosis of type of diseas...
Multimodal machine learning studies show promise in brain aging23; however, most rely on structural magnetic resonance imaging (MRI), overlooking brain network dynamics. Complex spatiotemporal dimensions can be tracked with spatial accuracy through functional magnetic resonance imaging (fMRI) and with mill...
Multi‐contrast imagingtumor responsequantitative MRIlow‐field MRIPurpose: Magnetic resonance-guided radiation therapy (MRgRT) has shown great promise for localization and real-time tumor monitoring. However, to date, quantitative imaging has been limited for low field MRgRT. This work benchmarks ...
PURPOSE: The goal of this study was to estimate pre- and post-gadolinium-enhanced high-spatial resolution susceptibility-weighted imaging (SWI) in patients with brain neoplasms. MATERIALS AND METHODS: A total of 17 patients (8 women, 9 men) with brain neoplasms participated in this study. In ...
not easily distinguishable from one with another, using conventional imaging [10]. Even with the advanced imaging sequences, such as DWI, MR spectroscopy, and dynamic susceptibility contrast (DSC)/Dynamic contrast-enhanced (DCE) MRI, differentiating brain lymphomas from the other brain tumors are st...
Dynamic, contrast-enhanced perfusion MRI in mouse gliomas: correlation with histopathology. Furthermore, measurements of rCBV from MRI data were in good agreement with histological measurements of MVD from the same tumors. Postcontrast enhancement ... S Cha,G Johnson,YZ Wadghiri,... - 《Magnetic...
