应用快速团注顺磁性对比剂的MRI为测量局部脑血液动力学提供了可能性。许多研究已证明,颅内脑膜瘤术前栓塞可减少病灶的血供,从而减少随后手术中失血。作者研究的目的是:①特性化脑膜瘤部分栓塞前、后局部血容量rBV的变异。②比较采用FLASH成像和EPI的rBV重建图。③用rBV图预见栓塞技术的效果。 作者对9例脑膜瘤病人(男、女各半,平均年龄57岁)做了18次检查,9例病人均施行了栓塞及
The use of rapid bolus injection of paramagnetic contrast agents provides the possibility of measuring local cerebral hemodynamics. Many studies have shown that preoperative embolization of intracranial meningioma can reduce the blood supply to the lesion, thereby reducing blood loss during subsequent surgery. The purpose of the study is: ① characteristics of meningioma before and after partial embolization of local blood volume rBV variation. ② Comparison of FLB imaging and EPI rBV reconstruction map. ③ with rBV map foresee the effect of embolic technology. The authors performed 18 examinations on nine patients with meningioma (half male and half female, mean age 57 years), embolization in 9 patients,
