Synthetic MRI and FSE-PROPELLER duo diffusion-weighted imaging to differentiate malignant from benign head and neck tumors

Accurate determination of the preoperative classification of histology of head and neck tumor remains a challenge. The aim of the study was to evaluate the feasibility and capability of synthetic MRI and stimulus and fast spin echo diffusion-weighted imaging (FSE-PROPELLER duo-DWI) for the differentiation of malignant from benign head and neck tumors. The results quantitively demonstrated the feasibility and also showed that T2 value is comparable to ADC value, and the combination of T2 and ADC values could provide improved diagnostic efficacy.
