例如,显性遗传阿尔茨海默病网络(DIAN)研究的MRI协议包括ADNI 3 ASL MRI序列,纵向早发性阿尔茨海默病研究(LEADS)和标准化集中式阿尔茨海默病及相关痴呆症神经成像(SCAN)也采用了相同的序列。其他大型研究则采用略有不同的采集方案实施ASL MRI,或者使用单个PLD(例如,遗传性额颞叶痴呆倡议[GENFI]),或使用多PLD协议(...
CHICAGO, Nov. 20 (Xinhua) -- MRI brain scan may help predict whether older people will develop dementia, showed new research at U.S. universities released on Tuesday. In a small study, MRI brain scans predicted with 89 percent accuracy who would go on to develop dementia within three years...
MRI has better resolution than CT and offers better visualization for study both functional and structural brain abnormalities,including tumors,cerebrovascular disease,stroke,demyelinating diseases,dementia,infectious diseases and epilepsy.Magnetic resonance angiography(MRA)generates pictures of the arteries to ev...

第IV组服用标准剂量的欧乃影(Omniscan)前获得第一组影像,服用标准剂量 (0.1mmol/kg)的欧乃影(Omniscan) 4分钟后获得第二组影像,共获得两组3DT1加权 斜冠状位成像(脉冲重复间隔时间(TR) =20ms;回波时间(TE) =6ms;翻转角=25度; 平面分辨率-0.86mmx0.86mm;层厚4mm)。由Tl-加权检査矢状位系列,辨别定向垂直...
Until recently this required the use of separate scanners with subsequent image coregistration. Integrated PET/MRI scanners remove these operational limitations; furthermore the simultaneous scan acquisition permits evaluation of the inter-re ... 展开 ...
Hippocampal, amygdalar and global brain atrophy on brain MRI have been proposed as early markers of Alzheimer's disease. In the Rotterdam Scan Study, a population-based study of age-related brain changes in 1077 non-demented people aged 60-90 years, we investigated the association between plasma...
AI can program an MRI cardiac scan that is planned by an expert MRI technologist, including four-chamber, two-chamber, left ventricular outflow tract, right ventricular outflow tract, and short axis views, without the presence of a cardiac specialist to ensure the scan’s optimization. In ...
