Synopsis

Keywords: Hepatobiliary, Biliary

Motivation: Explore surveillance of Intraductal Papillary Mucinous Neoplasms (IPMN) at 0.55T, as an alternative to high field strength systems.

Goal(s): To assess the image quality at 0.55T and its impact on radiologists' confidence in evaluating IPMN versus 1.5T/3T

Approach: Images from 39 patients with IPMN who underwent 0.55T and 1.5/3T MRI were rated by 7 blinded radiologists for image quality and diagnostic certainty. Pearson correlation analysis performed

Results: A strong positive correlation existed between image quality and rater’s confidence. Negligible differences in confidence observed between 0.55T and 1.5T/3T for images with quality scores≥5.

Impact: 0.55T can be used for IPMN surveillance without compromising diagnostic effectiveness
