Abstract:
Objective To explore the value of MRI functional imaging in the differential diagnosis between inflammatory pseudo-tumors and malignant tumors in the parotid gland.Methods A total of 20 cases with malignant tumors of the parotid gland and 15 cases with inflammatory pseudotumors of the parotid gland were retrospectively analyzed,and all patients were underwent enhanced MRI examinations of the maxillofacial region.All patients had complete MRI examination data and were confirmed by surgical pathology or clinical follow-up results.The morphological manifestations and the characteristics of MRI functional imaging of the parotid gland tumors that was time-signal intensity curve(TIC)type,apparent diffusion coefficient(ADC)were observed,and all imaging mani-festations data of the two groups were statistically analyzed via the x2 test,respectively.Results There were no statistical differ-ences in the morphological manifestations and functional imaging characteristics(TIC type and average ADC value)between the two groups(P＞0.05),while there was statistical difference in maximum ADC value between the two groups(P=0.017).Conclusion There is an overlap in the imaging characteristics of inflammatory pseudotumors and malignant tumors in the parotid gland.The wide distribution range and higher maximum value of ADC in multiple measurements of parotid gland inflammatory pseudotumors have certain significance for the differential diagnosis,thus guiding the clinical formulation of treatment plans.
