T2 mapping and readout segmentation of long variable echo-train diffusion-weighted imaging for the differentiation of parotid gland tumors

•The purpose of this study was to investigate the differential diagnostic value of radial turbo spin-echo (TSE) T2 mapping and readout-segmented echo-planar imaging diffusion weighted image (RESOLVE DWI) in parotid gland tumors.•T2 mapping, RESOLVE DWI, and the combination of the two methods can all be used to quantitatively diagnose differential parotid gland tumors.•The combined effect of the two methods was similar to the effect when used alone. T2 value is comparable to ADC value.
