Abstract

Abstract:

Objective: Imaging modalities for pancreatic intraductal papillary mucinous neoplasm (IPMN) often provide a large amount of information, and an adequate comparison of their diagnostic efficacies cannot be made by simply referring to the diagnostic accuracy rates. The aim of the study was to apply a novel scoring system to evaluate the pancreatic IPMN diagnostic efficacy of transabdominal ultrasound (TAUS), computed tomography (CT), and magnetic resonance imaging (MRI).

Methods: The clinical and diagnostic imaging data of 42 patients with pancreatic IPMN diagnosed at Fujian Medical University Union Hospital between January 2014 and November 2020 were retrospectively analyzed. We applied our scoring system for the quantitative, location, and qualitative diagnosis of each imaging modality, and the diagnostic efficacy was determined.

Results: The mean rank scores of quantitative diagnosis for MRI, CT, and TAUS were 53, 48.96, and 48.54, respectively (P = 0.267). The mean rank scores of location diagnosis for these three methods were 51.72, 49.58, and 48.97, respectively (P = 0.752). The mean rank scores of qualitative diagnosis for MRI, CT, and TAUS were 59.69, 41.08, and 51.18, respectively; the difference was statistically significant (P = 0.015).

Conclusions: The novel scoring system could comprehensively and accurately evaluate the diagnostic efficacy of TAUS, CT, and MRI for pancreatic IPMN. MRI had the highest quantitative, localization, qualitative, and comprehensive diagnostic efficacy.
