Pre- and Post-Treatment Diffusion-Weighted Imaging Characteristics of Sinonasal Adenoid Cystic Carcinoma

This case series suggests that DWI could serve as a non-invasive imaging tool for evaluating post-treatment response of sinonasal ADC. Post-treatment changes in ADC potentially correlate with treatment response and disease progression. Hence, DWI could play a supplemental role in monitoring therapy, highlighting its potential in guiding clinical management decisions for patients with sinonasal ACC.
