Dual-layer spectral detector computed tomography for improving the demonstration of the communication between intraductal papillary mucinous neoplasms and pancreatic duct.

ABSTRACT:

Background

Ductal communication is a critical discriminator for differentiating intraductal papillary mucinous neoplasms (IPMNs) from other pancreatic cystic neoplasms. This study evaluated dual-layer spectral detector computed tomography (DLCT)-derived virtual monoenergetic images (VMIs) for displaying IPMN-duct communication compared to conventional polyenergetic images (PEIs) and magnetic resonance cholangiopancreatography (MRCP).

Methods

A total of 35 patients with IPMNs from August 2021 to September 2023 were enrolled in this cross-sectional study. PEIs and VMIs (40/50/60/70 keV) were reconstructed at arterial phase (AP) and portal venous phase (PVP). Quantitative metrics [attenuation difference (AD), signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR)] for pancr
