摘要目的磁敏感加权成像(SWI)也许有助于显示多发性硬化白质病变的范围。该项研究的目的是评价“中央静脉征”对于多发性硬化的诊断价值。方法在一项3.0 T MRI研究中,包括14例病人的28个白质病灶,包括至少一个直径>5 mm的局限性病灶以及不多于8个直径>3 mm的非融合性病灶。仅对在FLAIR序列上显示的直径>5 mm且与SWI上相对应的白质病灶进行“中央静脉征”评价。结果 5例病人符合McDonald修订的多发性硬化诊断标准,而另外9例 Abstract Objective Magnetic resonance susceptibility imaging (SWI) may help to reveal the extent of multiple sclerosis. The purpose of this study was to evaluate the diagnostic value of “central venous sign” for multiple sclerosis. Methods In a 3.0-T MRI study, 28 white matter lesions were included in 14 patients, including at least one localized lesion> 5 mm in diameter and no more than 8 non-fusion lesions> 3 mm in diameter. White vein lesions> 5 mm in diameter and corresponding to SWI were evaluated for “central venous sign” only on the FLAIR sequence. Results Five patients met McDonald’s revised diagnostic criteria for multiple sclerosis while the other nine patients
