Abstract:
Objective To assess the characterization and usefulness of contrast enhanced ultrasound (CEUS)to diagnose solid focal lesions of pancreas(s-FLPs)in comparison to contrast enhanced computed tomography(CECT).Methods Forty-nine s-FLPs with final diagnosis were studied with low mechanical index CEUS and CECT.The enhanced patterns and diagnostic capability of CEUS were analyzed,and these results were compared with those from CECT.Results ①In CEUS,the perfusion of capillary could be detected in vascular phase.②The concordance of dual-phases enhanced patterns between CEUS and CECT was 73.5%(36/49).The concordance of enhanced level between early parenchymatous perfusion phase in CEUS and pancreatic phase in CECT could achieve 87.8%(43/49).Hypo/hypo enhancement was the most common enhanced pattern of pancreatic carcinoma in CEUS and CECT.③There was no statistical significance between CEUS and CECT in the differential diagnostic.Conclusions The concordance of enhanted patterns between CEUS and CECT is satisfactory.CEUS is similar to CECT in the differential diagnosis of s-FLPs.CEUS would become an important non-invasive diagnostic method for s-FLPs.
