Dynamic contrast‐enhanced MRI has demonstrated improved diagnostic capability of tumor masses in the salivary glands and elsewhere in the body. Distinct enhancement curves can be generated based on the time points of acquisition, resulting in improved differentiation of tumors (Yabuuchi et al. 2003; Shah et al. 2003; Alibek et al. 2007). However, data demonstrate similar characteristics in Warthin's tumor and malignant tumors, with a rapid increase in the signal intensity post‐contrast. Pleomorphic adenoma demonstrates a more gradual increase in intensity (Yabuuchi et al. 2003; Alibek et al. 2007). Primary salivary duct carcinomas have also demonstrated the rapid enhancement as well as low ADC values, as are seen with the more common primary malignancies of the salivary glands (Motoori et al. 2005).
