摘要目的扩散加权成像(DWI)上边界不清的边缘高信号和低信号核心是进行性多灶性脑白质病(PML)的典型特征。本研究旨在探索相对于b值为1 000 s/mm~2(b1000),b值
Abstract Objective To investigate the characteristics of progressive multifocal leukoencephalopathy (PML) in diffuse weighted imaging (DWI) with unclear marginal high signal and low signal core. The purpose of this study was to explore the b value of 1 000 s / mm ~ 2 (b1000) relative to the b value
