T1SE与T2SE是颅脑MR检查的两个基本序列,一般而言,T1SE显示病变解剖部位,而T2SE表明病变性质.液体衰减反转恢复序列(FLAIR)是近年来开发并应用于常规的又一基本序列.它使用较长的TE产生脑脊液信号值为零的重T2加权像.由于它的原理,使得脑沟,脑裂,脑室旁脑实质显示更加清晰.而增加了T1加权的T1 FLAIR.较T1SE可以有...
CONCLUSION: High-resolution T1- and T2-W volumetric sequences can be used in clinical MRI in the very preterm brain to provide both diagnostic and morphometric information. 展开 关键词: MRI Preterm brain Neonates T1- and T2-weighted imaging Relaxation times Myelination Sulcation ...
MRI是基于人体内氢质子(1H)含量的成像方法,不同组织内自由水1H及脂肪1H含量均不相同,T1值亦不同,通过测量组织T1值鉴别不同类型病变正是基于这一原理。本研究选取3种肝脏局灶性病变:肝血管瘤、肝细胞癌及肝转移瘤,结果发现3组病变初...

In the CMR analysis, the median PMR was 1.37 (interquartile range [IQR], 1.13–1.58), and the HIP group had a significantly higher PMR than the non-HIP group (1.61 [IQR, 1.43–2.11] versus [vs.] 1.14 [IQR, 1.00–1.26], p < 0.001).There was no significant difference in left...
