[Abstract] Objective To explore the value of MRI signs combined with ADC value in the differential diagnosis of pituitary macroadenomas and sellar meningiomas. Materials andMethods Forty-two cases of pituitary macroadenomas and 40 cases of sellar meningiomas confirmed by pathology, were analyzed retrospectively. All cases were examined by traditional magnetic resonance imaging (MRI) and diffusion-weighted imaging (DWI) before operation.The apparent diffusion coefficient (ADC) value was measured in the solid part of the tumor and compared with the results of pathological diagnosis. t-test, Chi-square test were used in statistical methods, and the diagnostic efficacy of each parameter in differentiating the two groups of tumors was evaluated by the receiver working characteristic (ROC) curve.Results Between pituitary macroadenomas and sellar meningiomas, significant enhancement (33%/95%, χ2＝33.581), waist sign (93%/7.5%, χ2＝50.831), wrapped around internal carotid artery (95%/57.5%, χ2＝16.390), enlarged sella turcica (93%/52.5%, χ2＝16.998), pituitary unrecognizable (95%/47.5%, χ2＝23.135) and pituitary stalk invisible (90%/62.5%, χ2＝7.761) were statistically significant (P＜0.05). The ADCmax (ADCmean and ADCmin) of pituitary macroadenoma and sellar meningioma was (1.126±0.266)×10-3 mm2/s and (0.855±0.176)×10-3 mm2/s [(1.052±0.271)×10-3 mm2/s and (0.817±0.177)×10-3 mm2/s, (0.971±0.288)×10-3 mm2/s and (0.777±0.182)×10-3 mm2/s, P＜0.001]. Among ADC values, ADCmax demonstrated good performance with an AUC of 0.877 (95% CI, 0.791—0.962) and when the cut-off of ADCmax is 0.970×10-3 mm2/s, the sensitivity and specificity of distinguishing them are 81% and 92.5%.Conclusions The basic signs of MRI combined with ADC value have high clinical value in the diagnosis of pituitary macroadenomas and sellar meningiomas, Which can improve the accuracy of preoperative diagnosis.
