Abstract:
Objective To investigate the value of ADC histogram in the differential diagnosis of angiomatous meningioma (AM) and hemangiopericytoma (HPC)and to screen out the best diagnostic parameter.Methods The MRI data of 21 cases with AM and 22 cases with HPC confirmed by surgical pathology were analyzed retrospectively.The ROI were drawn on the maximum cross section of the tumor on ADC maps,and the ADC histogram analysis was performed using the software named Mazda.Then the histogram parameters were statistically analyzed to find out the statistically significant parameters between the two groups,and the ROC curve was drawn to evaluate their diagnostic efficacy.Results ADCvariance ,ADC1th and ADC10th had statistical significances between the two groups (P＝0.030,0.002 and 0.02 1 ). ADC1th had the best diagnostic efficacy among them,with the optimal cut-off value of 0.086×10－3 mm2/s,the AUC was 0.814(P＝0.003),and the sensitivity and specificity were 86.70%and 64.70%,respectively.ADCvariance took the second place,for the AUC was 0.725 (P＝0.030),and the sensitivity and specificity were 7 6.50%and 80.00%,respectively.Conclusion The ADC histogram is of great value in the differential diagnosis of AM and HPC,and the ADC1th is the most effective parameter.
