目的探讨128层螺旋CT多期扫描技术与MRI在胰腺癌中的影像表现及病理对照分析,为胰腺癌治疗提供一定的诊断价值。方法选取我院2012年8月~2015年3月做过多层螺旋CT扫描胰腺肿块的患者64例,均由病理切片证实,其中胰腺癌32例,胰腺炎32例,并将胰腺炎和胰腺癌强化后的CT值进行比较分析。结果果1与其他各时相比较,螺旋CT胰腺期薄层扫描显示胰腺癌直接征象(胰腺肿块)最佳(P<0.05),而对胰腺癌间接征象的显示,各期扫描图像差异无显著性(P>0.05);2螺旋CT三期检查显示胰腺癌直接征象(胰腺肿块)较MRI(T2W+MRCP)更佳(P<0.05),而对显示胰腺癌间接征象差异无显著性(P>0.05);3与MRI(T2W+MRCP)比较,螺旋CT三期扫描诊断胰腺癌的准确率较高(P<0.05)。结论 128层螺旋CT三期扫描特别是胰腺期薄层扫描及MRI的SE序列T1W+脂肪抑制技术对胰腺癌直接征象显示率较高,有助于提高胰腺癌诊断的准确性。
Objective To investigate the imaging features and pathological analysis of 128-slice spiral CT multi-phase scanning and MRI in pancreatic cancer and provide some diagnostic value for the treatment of pancreatic cancer. Methods Sixty-four patients with multi-slice CT scan of pancreatic masses from August 2012 to March 2015 in our hospital were confirmed by biopsy, including 32 cases of pancreatic cancer and 32 cases of pancreatitis. Pancreatitis and pancreas CT value of cancer after enhanced analysis. Results 1 Compared with other periods, spiral CT pancreata scan showed the best direct imaging (pancreatic mass) of pancreatic cancer (P <0.05), while the indirect signs of pancreatic cancer showed no significant difference (P> 0.05) .3phase spiral CT showed that the direct signs of pancreatic cancer (pancreatic tumor) were better than those of MRI (T2W + MRCP) (P <0.05), while the indirect signs of pancreatic cancer showed no significant difference > 0.05). 3 Compared with MRI (T2W + MRCP), the accuracy of three-phase spiral CT in the diagnosis of pancreatic cancer was higher (P <0.05). Conclusions The three-phase CT scanning of 128-slice spiral CT, especially the pancreatic thin-section scanning and T1W + fat suppression of SE sequence of MRI, has a higher rate of direct signs of pancreatic cancer, which is helpful to improve the diagnostic accuracy of pancreatic cancer.
