摘　　要：目的 探讨能谱CT成像对胰腺癌术前可切除性评估的临床应用价值。方法 对46例经手术病理证实的胰腺癌患者进行能谱CT扫描。应用能谱CT综合评价癌肿与周围主要血管、脏器的关系及肝脏、腹腔淋巴结转移情况。结果 能谱CT术前正确判断8例存在肝转移,11例存在淋巴结转移。经统计学分析，能谱CT评估动脉受侵的特异性为98.9%，敏感性为95.2%；评估静脉受侵的特异性为100%，敏感性为90.6%；判断总体血管受侵的特异性为99.2%，敏感性为93.5%。结论 能谱CT可准确判断胰腺癌是否发生肝转移和淋巴结转移，并可提高对胰周血管是否受侵判断的特异性和敏感性。Objective To study the value of spectral CT in the preoperative assessment of resectability in patients with pancreatic carcinoma. Methods A total of 46 patients with pancreatic carcinoma proved by pathology accepted spectral CT scan. The resect ability of these tumors were evaluated preoperatively, which included the relationship between tumors and vessels as well as organs, the evaluation of hepatic metastasis and celiac lymph node metastasis. Results All hepatic metastases （8 cases） and celiac lymph node metastasis （10 eases） had been found by spectral CT. With statistical analysis, the specificity and the sensitivity of arterial invasion was 98. 9% and 95. 2%, respectively. The specificity and the sensitivity of vein invasion was 100%, 90. 6%, respectively. The specificity and the sensitivity of overall vascular invasion was 99.2% and 93.5%, respectively. Conclusion Spectral CT can be used to evaluate the hepatic metastasis and celiac lymph node metastasis,improve specificity and sensitivity of peripancreatic vascular invasion.
