Computed high-b-value high-resolution DWI improves solid lesion detection in IPMN of the pancreas.

ABSTRACT:

Objectives

To examine the effect of high-b-value computed diffusion-weighted imaging (cDWI) on solid lesion detection and classification in pancreatic intraductal papillary mucinous neoplasm (IPMN), using endoscopic ultrasound (EUS) and histopathology as a standard of reference.

Methods

Eighty-two patients with known or suspected IPMN were retrospectively enrolled. Computed high-b-value images at b = 1000 s/mm² were calculated from standard (b = 0, 50, 300, and 600 s/mm²) DWI images for conventional full field-of-view (fFOV, 3 × 3 × 4 mm³ voxel size) DWI. A subset of 39 patients received additional high-resolution reduced-field-of-view (rFOV, 2.5 × 2.5 × 3 mm³ voxel size) DWI. In this cohort, rFOV cDWI was compared against fFOV cDW
