MRI Scans MRI imaging can be used across most of the body and is particularly good at looking at soft tissues. An MRI can either be a full body scan or focus on a specific body area. Conditions MRI scans can look for include: Brain and spine: This includes multiple sclerosis, stroke, ...
Stroke and Alzheimer disease share risk factors and often co﹐ccur, and both have been reported to have a higher prevalence in African〢mericans. However, the interaction of race, stroke, and Alzheimer disease has not been established. We compared MRI and PiB PET biomarkers of nonヾemented ...
In the adjusted model, the odds of having a positive amyloid PET scan were lower for Asian participants (odds ratio [OR], 0.47; 95% CI, 0.37-0.59; P < .001), Black participants (OR, 0.71; 95% CI, 0.60-0.84; P < .001), and Hispanic participants (OR, 0.68; 95% CI, ...
Initial research in the realm of whole-body MRI, particularly under the scope of Imiomics [72], has laid the groundwork for establishing a proof-of-concept normative database. This database focused on quantifying average distributions of adipose and lean tissue within an asymptomatic population. ...
MR/PET scanning is an exciting novel imaging modality that can assess disease activity together with assessments of cardiac anatomy, function, and tissue composition during a single scan. The lower associated radiation doses may be particularly important for the clinical imaging of younger patients. ...

MRI is usually used for T staging with an intense discussion concerning the preferable imaging modality for regional lymph node staging as PET/CT, MRI, and multi-slice spiral CT are all improving rapidly. Is this review, we summarize recent literature on 18F-FDG PET and PET/CT imaging of ...
treatment FDG-PET/CT for the primary site, the sensitivity was 79.9%, specificity was 87.5%, PPV was 58.6%, and NPV was 95.1%. PET/MR成像在过去的十年中已经在研究环境中投入使用,近年来已经进入了临床实践。PET/ MR成像具有减少辐射剂量的优势,因为Mr用于衰减校正,避免了获得CT;在经常接受放疗的肿瘤...
MRI navigators can be incorporated into serial anatomical and functional MRI acquisitions during standard PET/MR imaging to capture motion throughout the dynamic PET scan without increasing MRI scan time. As more approaches for motion correction become widely available including emerging machine learning ...
Small animal PET data was acquired with a nanoscan PET scanner (Mediso Medical Imaging Systems, USA). After the induction of anesthesia, the animals were positioned with their heads in the center of the field of view and were fixed in the PET scanner in the prone head first position (HFP...
