Purpose TThe prevalence of asymptomatic pancreatic cysts is estimated at 8%. However, due to the widespread utilization of cross-sectional imaging and continuous enhancements in image quality, the detection of incidental pancreatic cysts has surged over recent decades. Up to 44.7% of magnetic resonance cholangiopancreatography (MRCP) scans reveal pancreatic cystic lesions these, intraductal papillary mucinous neoplasms (IPMN) are particularly common. IPMNs can be categorized into three types based on imaging and / or histology: main duct IPMN (MD-IPMN), branch duct IPMN (BD-IPMN)...
Read more Methods and materials Patients undergoing MRI of the abdomen from May 1, 2023, to December 31, 2023 were prospectively enrolled. MRI images were independently assessed and rated on a four-point Likert scale by two experienced radiologists. Quantitative analysis was focused on determining the size of the smallest detectable lesion and assessing signal contrast. Qualitative analysis examined various aspects, including the depiction of communication with the main pancreatic duct (MPD), identification of complex features such as dilated MPD, mural nodules and septa, as well...
Read more Results DL HASTE demonstrated markedly superior lesion contrast compared to conventional HASTE (p < 0.001), enabled the detection of smaller lesions (p < 0.001), depicted better the connection to the MPD (p = 0.003), as well as facilitating the identification of complex features (p = 0.002) and peripancreatic lymph nodes (p < 0.001).
Read more Conclusion DL HASTE improves detection and characterization of IPMNs compared to conventional HASTE in spite of shorter acquisition times. This could greatly facilitate follow-up MRI scans of IPMN, allowing for diagnostic imaging in under 10 minutes while maintaining excellent lesion characterisation. The rapid scanning time is crucial for accommodating the expanding patient population affected by this common condition, thereby ensuring timely and effective follow-up care.
