您要查找的是不是:
- flow void effect 流动空隙效应
- flowing void effect 流空效应
- Such flow voids are best seen on long TR SE images. 这种现象在长TR(SE)信号影像上可以清楚地观察到。
- MRI can show that the normal flow void of the dural sinus is disappeared, instead of abnormal high or equality intensities. MRI出现静脉窦正常流空效应消失,代之以异常等或高信号影;
- The main finding of MRI diagnosis for cerebral aneurysm and AVM was “flow void signal”. There were various demonstrative of vessals grade by different MRI sequences and MRA method. 结果:“流空信号”是MRI诊断脑动脉瘤及脑血管畸形的主要征象,不同的MRA成像方法或序列对脑血管分级的显示亦不一致。
- Vascular "flow void" signal, equal or lower signal of conus on T 1WI and higher signal on T 2WI, were shown in sigittal planes of MRI in all of 19 cases. No "flow void" or "hemorrhage" signal was found in spine cord. 19 例MRI矢状面上均见血管流空信号,髓内无流空或出血信号,矢状面圆锥部均见T1 WI等或低信号,T2 WI高信号。
- MRI identified the enlarged portal vein without flow void signal, replaced by liver cancer signal intensity, and the enlarged interhepatic portal branches with “bamboo-like or staghorn” appearance. MRI表现为门脉增粗,其内失去流空信号,代之以肝癌信号充填。增粗的门脉呈团块状、竹节状或鹿角状。
- The lesion is exophytic towards the third ventricle and encases bilateral carotid arteries, although, flow voids are intact. 病变向第三脑室呈外生性生长,并包绕双侧颈动脉(流空信号仍然正常)。
- In slice 9, look for the internal carotid arteries and the sigmoid and straight sinuses, comparing the MR flow voids to the Tc-labeled red cells. 在层面9中,请注意颈内动脉,乙状窦及直窦比较铊标记的红细胞与磁共振上空白处的关系。
