Comparative Study of Dynamic Susceptibility Contrast Perfusion MR Images between Warthin's Tumor and Malignant Parotid Tumors

다국어 초록 (Multilingual Abstract)

Objectives: To identify diagnostically meaningful differences between Warthin’s tumor and malignant masses in the parotid gland by dynamic susceptibility contrast (DSC) MR imaging Methods: Eleven malignant parotid tumors and 9 Warthin’s tumors were included. MR imaging was performed on all patients. Signal intensity time curves of tumors were obtained by DSC MR imaging and dynamic susceptibility contrast percentages (DSC%) were calculated. Results: No significant difference was observed between malignant tumors and Warthin’s tumors ( P = 0.437), although DSC% values tended to be higher for Warthin’s tumors. Conclusions: Warthin’s tumor tended to have higher DSC% values than malignant parotid tumors, but this difference was not significantly different.
