Abstract:
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 ratio-time(CER-T) curve, the enhanced degree, and pattern of intraspinal tumors have the significant value for the histologic diagnosis and the calculation of vascularity.
