- Abstract:
- Objective To study the application value of magnetic resonance imaging (MRI) and multi-slice spiral computed
tomography angiography (MSCTA) in the diagnosis of peripancreatic vascular invasion in pancreatic cancer. Methods A total of
86 patients with pancreatic cancer were enrolled. According to surgical results, it was found that there were 63 cases with
peripancreatic vascular invasion and 23 cases without vascular invasion.All patients underwent MRI and MSCTA. The diagnostic
efficiencies of two detection methods in peripancreatic vascular invasion, the detection rates for different grades of vascular
invasions, and the detection rates for different types of vascular invasions were statistically analyzed. Results There was no
significant difference in diagnostic sensitivity and specificity between MSCTAand MRI (96.83% vs 85.71%, 91.30% vs 86.96%
P>0.05). The diagnostic accuracy of MSCTA was significantly higher than that of MRI (95.35% vs 86.05%, P<0.05). The
coincidence rates between MSCTA and surgical results in the diagnosis of grade 1-4 vascular invasions were 94.29%, 98.04%,
96.36%and 95.83%, which were similar to those betweenMRI and surgical results (88.57%, 92.16%, 92.73%and 87.50%), without
statistical differences (P>0.05). Moreover, there was no significant difference in the detection rate for different types of vascular
invasions between two methods (P>0.05). Conclusion MSCTA is more accurate in detecting peripancreatic vascular invasion in
pancreatic cancer.
