Abstract
Pancreatic mucinous cystic neoplasms (MCNs) are benign lesions with potential for malignant transformation. Accurate differentiation from other pancreatic cystic lesions remains challenging through conventional imaging modalities. Cinematic rendering (CR) is an advanced 3D computed tomography (CT) post-processing technique that generates photorealistic images with enhanced texture mapping and improved anatomical detail. It has not been previously discussed as a diagnostic tool for MCNs. Through added depth perception and tissue differentiation, CR complements conventional CT by enhancing visualization of morphology, internal components such as septations, calcification patterns, vascular involvement, and features suspicious of malignancy. It also helps with assessment of resectability and surgical planning by clearly highlighting vascular involvement. It is of note that further research is needed to quantify its added diagnostic value and optimize its role in clinical decisions in the evaluation of MCNs.
