Core Tip
Core Tip: In this study, the diagnostic features of diffusion-weighted imaging and semiquantitative and quantitative perfusion magnetic resonance imaging (MRI) parameters were evaluated in salivary gland tumors. The apparent diffusion coefficient (ADC) values of pleomorphic adenomas (PMAs) were significantly higher than those of Warthin's tumors (WTs), other benign tumors (OBTs), and malignant tumors (MTs). On semiquantitative MRI, PMAs were distinguished from all other tumors by their long Tpeak times and lack of washout. WTs had the shortest Tpeak and highest washout ratio values. For quantitative perfusion MRI parameters, the Kep value of WTs was significantly higher than those of other tumors. The Ve values of WTs and OBTs differed significantly from those of PMAs and MTs.
