目的在原发或继发脑肿瘤治疗之后对其行增强MRI监测,确定相对脑血容量(rCBV)分数在区分强化肿块中高度复发肿瘤与治疗相关坏死(TRN)的精确度。方法经机构审查委员会同意,符合HIPAA,回顾性研究30例行复发强化肿块切除术的病人,这些病人均在行外科手术和放疗(行或不行化疗)后再次出现强化的肿块。
Objective To perform enhanced MRI monitoring of primary or secondary brain tumors to determine the relative accuracy of relative cerebral blood volume (rCBV) scores in distinguishing highly recurrent tumors from those associated with treatment-related necrosis (TRN). Methods The HIPAA was approved by the Institutional Review Board and retrospectively reviewed 30 patients who underwent recurrent intensive lump resections that had recurred after surgery and radiation (with or without chemotherapy).
