血流方向是盆腔瘀血综合征诊断的一个重点标准诊断盆腔MRI是高分辨率T2WI,梯度回波序列,前后对比VIBE序列和具体的血管血流成像? High temporal resolution time resolved MR angiography (TWIST Siemens, TRICKS GE). Good correlation with grade of reflux seen at venography Imaging over 2 minutes, scan time 5 secs, free breathing post Gd Phase contrast MRI can also be useful Major disadvantage is supine position 高时间分辨率时间分辨率磁共振血管造影(TWIST Siemens, TRICKS GE)。与静脉造影显示的反流程度有良好的相关性成像超过2分钟,扫描时间5秒,Gd后自由呼吸MRI相衬也有用主要缺点是仰卧位 栓塞前MRI True FISP sequence, rapid 10 second scan! No IV contrast 3mm axial and coronal Locates origin of right gonadal vein Leads to quicker embolization, less radiation 真正的FISP序列,快速10秒扫描!没有静脉造影剂3毫米轴向和冠状确定右侧性腺静脉的起源可以更快地栓塞,减少辐射 MRI可以显示盆腔结构,除外下腰病变和清楚滴显示皮肤和阴道的静脉曲张。MR静脉造影可以发现高信号强度的卵巢和附件周围扩张静脉。 Phase contrast velocity mapping = useful tool in diagnosing PCS【Philips D 2014】 |
