摘要：

Purpose: Intracranial Hemangiopericytomas (IHP) are dural based tumors that frequently recur/metastasize. Unfortunately, their imaging appearance overlaps significantly with more benign meningiomas. We evaluated the use of diffusion weighted imaging (DWI) to differentiate IHP from meningioma. Methods: We compared MRI of IHP tumors (WHO Grades II/III) (n = 20) to meningioma (n = 48, WHO Grade I/ II). Findings: ADC values differed between IHP (1.05 x 10-3 mm2/s) and meningiomas (0.89 x 10-3 mm2/s) (p = 0.05). Normalized ADC ratios (nADC), differed between IHP and meningiomas (1.30 vs 1.07, p = 0.03). Conclusion: Importantly, a nADC cutoff of > 1.3 was specific (96%) but not sensitive (35%) for identifying IHP.
