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

VMI 40-50 keV significantly improved quantitative and qualitative image quality in the display of IPMN-duct communication over PEI and higher-keV VMIs, achieving diagnostic equivalence to MRCP. This supports DLCT as a practical alternative when MRCP is contraindicated or unavailable.
