摘要
对３７例椎管内肿瘤进行动态增强磁共振成像。结果表明：强化峰值在９０ｓ内仅见于血管母细胞瘤，１８０ｓ内多见于星形细胞瘤、脊膜瘤及转移瘤，神经鞘瘤的最大对比增强率高于脊膜瘤（Ｐ＜０．０５）。肿瘤的对比增强率——时间曲线。
The dynamic enhanced MR imaging of 37 patients with intraspinal tumors were performed. We found that the enhancement peak within 90s was shown only in hemangioblastoma, within 180s was shown in most astrocytomas, meningiomas, and metastases. The maximum contrast enhancement ratio (MCER) of neurilemmoma is higher than that of meningioma(P>0.05). We conclude that the contrast enhancement ratiotime(CER-T) curve, the enhanced degree, and pattern of intraspinal tumors have the significant value for the histologic diagnosis and the calculation of vascularity.
