Results

74 patients were affected by complete PD and 12 by incomplete PD. 

Hypointensity in T1 sequences and irregularity of the main pancreatic duct were significantly more often limited to dorsal pancreas in patients aged <40 (p=0.03; p=0.02) while the entire pancreas was significantly involved in patients aged >60 (Fig.1;Fig.2). Isolated dorsal T1-hypointensity was observed in 86% of the patients aged <40 while involvement of the entire pancreas was observed in 50% of the patients aged >60 (Tab.1).

Increasing age was significantly associated with reduction in parenchymal thickness (p=0.0082), irregularity of parenchymal margins and branch-ducts dilatation (p=0.0002), but not with parenchymal hypointensity in T1 sequences (p=ns) (Fig.3).

When the reduction in parenchymal thickness was mild, there were no significant differences in distribution in the organ between the age groups (p=ns). When the reduction was more severe, the entire pancreas was involved in the older patients compared to a more limited involvement in younger patients (p<0,001). 

Dorsal involvement of the MPD was observed in 89% of patients aged <40 (Tab.2). 

Branch-duct dilatation was significantly associated with increasing age (p=0.0001), while no difference was observed in the site of dilatation.
