Aims and objectives
The detection rate of Pancreatic cystic neoplasms (PCNs) as incidental finding has shown a continuous increase in the last decade,
in particular in the elderly population.
However,
this is to be accounted more to the extensive use of cross-sectional imaging than to an effective increase of incidence in the general population [1].
Among the cystic lesions of the pancreas,
intraductal papillary mucinous neoplasia (IPMN) is one of the most frequent [2].
IPMNsare characterized by intraductal proliferation of neoplastic mucinous cells with consequent cystic dilation of...
Methods and materials
Patient Selection
Inclusion criteria: patients with EUS or pathological diagnosis of IPMN who underwent an MRI examination between July 2015 and December 2017 at Department of Radiology of University Hospital of Ancona,
Italy.
Exclusion criteria: lack of MRI examination,
contraindication to contrast media administration and lack of EUS,
pathological and clinical data.
MRI technique
MRI studies were performed with a 1.5-T scanner (GE Signa HdXt,
Milwaukee,
WI) and an eight-channel phased-array body coil.
The examination protocol included axial and coronal fast spin-echo (FSE) T2-weighted sequences,...
Results
A total of 33 patients were included (13 male,
21 female) with mean age 67 (range 43-82 y.o.) with an average of 2.1 of cystic lesions >5mm per patient and an average of cystic diameter of 15.2 mm.
Table 1 shows demographics and evaluation of WF and HRS by reader A.
Figure 2 shows IRA between the three readers for the WF and HRS with ICC values included between 0.623 and 0.905.
No significant differences between ICC were detected due to 95%CI overlap ( Fig....
Conclusion
The Fukuoka Guidelines for IPMN allowed for a reproducible evaluation of WF and HRS with moderate to good IRA in readers with different experience.
