Figure 1 Chart of the clinical course of all the branch duct intraductal papillary mucinous neoplasm patients.
1These two patients underwent resection after follow-up due to repeated pancreatitis or an increasing main pancreatic duct diameter. BD-IPMN: Branch duct intraductal papillary mucinous neoplasm; MNs: Mural nodules; EUS: Endoscopic ultrasonography; CE-EUS: Contrast-enhanced EUS.
Figure 2 Correlations between mural nodules height measured by each imaging modality and mural nodules height measured on pathological specimens.
A: A positive correlation was identified between MN height measured by CT and that measured on pathological specimens; B: A positive correlation was identified between MN height measured by EUS and that measured on pathological specimens; C: A positive correlation was identified between MN height measured by CE-EUS and that measured on pathological specimens. HCT: MN height measured by CT; HEUS: MN height measured by EUS; HCE-EUS: MN height measured by CE-EUS; HPath: MN height measured on pathological specimens; MN: Mural nodule; CT: Computed tomography; EUS: Endoscopic ultrasonography; CE-EUS: Contrast-enhanced EUS.
Figure 3 Comparison of measurement error values.
The measurement error values for CE-EUS were significantly lower than those for CT or EUS. |HCT-HPath|, measurement error value for CT; |HEUS-HPath|, measurement error value for EUS; |HCE-EUS-HPath|, measurement error value for CE-EUS. Statistically significant, aP < 0.05, |HCT-HPath| vs |HCE-EUS-HPath|, statistically significant, bP < 0.01, |HEUS-HPath| vs |HCE-EUS-HPath|. CT: Computed tomography; EUS: Endoscopic ultrasonography; CE-EUS: Contrast-enhanced EUS.
Figure 4 Receiver operating characteristic curve analysis.
Based on the receiver operating characteristic curve analysis, when 8.8 mm was utilized as the cut-off value for MN height, as measured by CE-EUS, the diagnosis of malignant BD-IPMN had an accuracy of 94%. BD-IPMN: Branch duct intraductal papillary mucinous neoplasm; MN: Mural nodule; CE-EUS: Contrast-enhanced endoscopic ultrasonography.
