Motivation: Imaging of sialolithiasis is critical for treatment planning, but standard CT involves radiation exposure, and MR sialography alone struggles to visualize calcified stones. A safer, more effective method is needed.
Goal(s): To evaluate the utility of fusion imaging combining MR sialography (MR-S) with CT-like images (CTLI) for diagnosis of sialolithiasis.
Approach: MRI scans of 60 patients were analyzed using MR-S, CTLI, and fusion imaging, and diagnostic accuracy was compared to conventional MRI.
Results: Fusion imaging significantly improved diagnostic sensitivity, specificity, and rater confidence compared to conventional methods.
Impact: The use of fusion imaging combining CT-like images and MR sialography eliminates the risks of radiation exposure and contrast injection, providing a highly noninvasive diagnostic tool for sialolithiasis. However, efforts should be made to reduce scan time.
