目的了解多层螺旋CT血管造影(MSCTA)技术在评价胰腺癌血管浸润的价值。方法采用MSCTA技术对38例胰腺癌患者进行术前检查,利用多平面重建和最大密度投影技术结合横断面图像对胰腺癌血管浸润情况进行评价,并与手术结果进行对照分析。结果 MSCTA检查结果显示38例胰腺癌患者中有12例(31.6%)存在血管浸润,手术结果显示有16例(42.1%)存在血管浸润,两种结果有较强的吻合度(kappa=0.665,P=0.000)。MSCTA检查的灵敏度为68.8%(11/16),特异度为95.5%(21/22)。结论 MSCTA技术评价胰腺癌血管浸润具有较高的正确率,且与手术结果有较强的一致性,具有一定的临床应用价值。
Objective To understand the value of multi-slice spiral CT angiography (MSCTA) in the evaluation of vascular invasion in pancreatic cancer. Methods 38 patients with pancreatic cancer underwent preoperative examination by MSCTA technique. The vascular invasion of pancreatic cancer was evaluated by multiplanar reconstruction and maximum density projection combined with cross-sectional images. The results were compared with the surgical findings. Results The results of MSCTA showed that there were vascular invasion in 12 of 38 patients (31.6%). The results showed that there were 16 cases (42.1%) with vascular invasion, and the two results showed a good agreement (kappa = 0.665, P = 0.000). The sensitivity of MSCTA was 68.8% (11/16) and the specificity was 95.5% (21/22). Conclusion The MSCTA technique has a high accuracy in assessing the vascular invasion of pancreatic cancer and has strong consistency with the surgical results and has certain clinical value.
