- W917507927 abstract "目的探讨骨巨细胞瘤的动态增强MRI及MR氢质子波谱的特点及其在骨巨细胞瘤诊断中的作用。方法采用3D fast SPGR序列对21例病理证实的骨巨细胞瘤进行动态增强扫描,并采用点分辨波谱序列（PRESS）对其中12例进行单体素MR氢质子波谱扫描,分别经过工作站处理,得到动态增强扫描时间-信号强度曲线（TIC）及MR氢质子波谱谱线。以手术病理为标准,对骨巨细胞瘤的动态增强扫描时间-信号强度曲线及MR氢质子波谱的特点进行分析。结果21例骨巨细胞瘤的TIC曲线中,19例为Ⅰ型曲线,2例为Ⅱ型曲线;12例MR氢质子波谱的谱线中,9例具有诊断价值,其中有2例出现明显的胆碱峰。结论骨巨细胞瘤的TIC曲线表现为速升下降型,^1H-MRS谱线缺乏胆碱峰或胆碱峰矮小。" @default.
