Synthetic MRI and amide proton transfer–weighted MRI for differentiating between benign and malignant sinonasal lesions

To explore the value of the synthetic MRI (SyMRI), combined with amide proton transfer–weighted (APTw) MRI for quantitative and morphologic assessment of sinonasal lesions, which could provide relative scale for the quantitative assessment of tissue properties. A total of 80 patients (31 malignant and 49 benign) with sinonasal lesions, who underwent the SyMRI and APTw examination, were retrospectively analyzed. Quantitative parameters (T1, T2, proton density (PD)) and APT
