目的探究多层螺旋CT胰周血管成像检查对胰腺癌胰周主要血管受侵的影像表现以评估手术可切除性的效果。方法对40例胰腺癌患者以64排128层螺旋CT扫描后,进行动脉期及门静期胰周血管三维成像。并结合患者原始图像,评判胰腺癌是否累及胰周血管,同手术结果对比。结果同手术结果比较,40例胰腺癌患者中,多层螺旋CT胰周血管成像术前评判21例能切除,在手术中有1例不能切除,20例能切除;多层螺旋CT胰周血管成像术前评判不能切除的19例,在手术中均未能切除。多层螺旋CT血管成像判断与手术结果符合率为97.5%,差异无统计学意义(P>0.05)。结论在胰腺癌切除手术前,以多层螺旋CT胰周血管成像评估,能提高诊断准确性,具有临床参考价值。
Objective To investigate the imaging findings of pancreatic peripancreatic vascular invasion by multi-slice spiral CT perfusion imaging in order to evaluate the effect of resectability. Methods Forty patients with pancreatic cancer underwent 64-slice 128-slice spiral CT scans and performed three-dimensional imaging of peripancreatic vessels in the arterial phase and portal phase. Combined with the patient’s original images, pancreatic cancer is assessed whether the peripancreatic vessels, compared with the surgical results. Results Compared with the surgical results, among the 40 patients with pancreatic cancer, 21 cases could be excised before multislice spiral CT perfusion imaging. One case was unresectable and the other 20 cases were resected. The multi-slice spiral CT peripancreatic vessels Nineteen patients with unresectable thoracotomy were excluded from the surgery. The coincidence rate of multislice CT angiography and surgical findings was 97.5%, with no significant difference (P> 0.05). Conclusion Before the resection of pancreatic cancer, multi-slice spiral CT perfusion imaging can improve the diagnostic accuracy and has clinical value.
