Abstract:
Objective To explore the application value of multi-slice spiral CT(MSCT)multi-planar reconstruction(MPR)technology for CT-guided puncture biopsy of pancreatic lesions.Methods A total of 104 patients with isolated pancreatic lesions who underwent CT-guided puncture biopsy were retrospectively enrolled,including 49 cases underwent MSCT-MPR assisted guided biopsy(MPR group)and 55 underwent MSCT-guided biopsy alone(non-MPR group).The success rate of puncture biopsy,the operating time,the times of needle adjustments,radiation dose-length product(DLP)and relative complications were recorded.Based on surgical pathology or follow-up(≥12 months)results,the sensitivity of biopsy was calculated.Results The success rate of one-time puncture was 100％in both groups.No significant difference of operating time was found between MPR([15.96±4.73]min)and non-MPR group([16.22±5.76]min,t=-0.250,P=0.803).MPR group had fewer times of needle adjustments([6.53±1.24]vs.[8.15±1.90],t=-5.201,P＜0.001)and lower DLP([946.02±143.54]mGy·cm vs.[1 095.53±338.50]mGy·cm,t=-2.988,P=0.004)than non-MPR group.During biopsy,minor bleeding occurred in 1 case of MPR group and 5 of non-MPR group,then all spontaneously improved without special treatment.The diagnostic sensitivity of biopsy pathology was 95.56％(43/45)in MPR group and 92.16％(47/51)in non-MPR group.Conclusion MSCT-MPR technology could improve the accuracy of CT-guided puncture biopsy of pancreatic lesions and reduce radiation dose.
