作者报道了MRA及Gd-DTPA增强MRA对17例幕上肿瘤血管表现的观察,DSA为对照组,评价MRA提供给神经外科制定治疗计划和决定手术通路的能力。17例中男8例,女9例,年龄19～65岁。颞叶8例,额叶3例,顶叶1例,枕叶1例,额颞区1例,鞍上区、基底节各1例。胶质细胞瘤6例(Ⅰ、Ⅱ、Ⅲ级各2例),恶性胶质瘤6例,原发神经外胚瘤(PNET)Ⅳ级2例,少突神经胶质瘤1例,颅咽管瘤1例,血管外皮细胞瘤1例。17例经常规SE序列MRI及Gd-DTPA增
The authors report the observation of MRA and Gd-DTPA-enhanced MRA in 17 cases of supratentorial tumor vessels. The DSA served as a control group to evaluate the ability of MRA to provide neurosurgical treatment plans and determine surgical access. There were 8 males and 9 females in 17 cases, aged 19-65 years old. 8 cases of temporal lobe, 3 cases of frontal lobe, 1 case of parietal lobe, 1 case of occipital lobe, 1 case of frontotemporal area, 1 case of suprasellar region and basal ganglia. Glioma in 6 cases (Ⅰ, Ⅱ, Ⅲ grade in 2 cases), 6 cases of malignant glioma, primary neuroectodermal (PNET) Ⅳ grade in 2 cases, oligodendroglioma in 1 case, craniopharyngioma 1 case of hemangioma, 1 case of hemangiopericytoma. 17 cases of conventional SE sequence MRI and Gd-DTPA increased
