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. ...
如前所述,造影增强MRI(Contrast-enhanced MRI, CE-MRI)可用于患者的疗效评估和肿瘤病变的检测标准,但它无法区分疑似病灶是进展恶化中的肿瘤还是治疗所致的非肿瘤损伤病变(如上述的治疗后辐射效应)。尽管这两种不同类型的病变在影像学方面均...
如前所述,造影增强 MRI(Contrast-enhanced MRI, CE-MRI) 可用于患者的疗效评估和肿瘤病变的检测标准,但它无法区分疑似病灶是进展恶化中的肿瘤还是治疗所致的非肿瘤损伤病变(如上述的治疗后辐射效应)。尽管这两种不同类型的病变在影像学方面均表现为对比增强的肿块,但二者预后截然不同。所幸的是,不同于CE-MRI,...
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...
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 ...
Deep Learning Enables Reduced Gadolinium Dose for Contrast-Enhanced Brain MRI (Journal of Magnetic Resonance Imaging 2018) 这是一篇医学图像增强的论文,介绍了研究人员正在使用人工智能来减少MRI检查后留在体内的造影剂的剂量。 提出背景 钆(gá,gadolinium)是一种用于对比材料的重金属,可增强MRI上的图像,作为一...
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...
