注液摇篮CT扫描技术在胃癌检查中的应用及诊断价值

目的：探讨注液摇蓝CT扫描技术在胃癌检查中的应用及诊断价值。方法：对128例胃癌病人以水作对剂，利用低张法摇蓝技术，变换体位行CT检查，作出术前CT分期，并与手术病理分期对照，结果：CT分期与临床分期符合率84．4％（108／128）。CT分期低估11例（8．6％），高估9例（7．0％），CT对肿大淋巴结的检出率＜1cm或≥1cm者分别为23．1％，76．9％，敏感性84．8％（167／197），特异性87．5％（98／112）。结论：以水作对比剂的注液摇蓝CT扫描技术能明显提高胃癌术前分期准确率，尤其在观察肿块与周期脏器结构关系及肿大淋巴结方面更具有优越性。

THE APPLICATION AND THE DIAGNOSTIC VALUE OF CT SCANNING WITH WATER-INFUSED CRADLE IN DETECTING CARCINOMA OF STOMACH

Objective To explore the application and the diagnostic value of CT scanning with water infused cradle.Methods In 128 cases,CT scanning in this way at different postures was performed in contrast to water.The results of CT scanning stages were also compared with those of operative pathologic detectable analyses.Results The coincident rate the results of CT scanning and clinical pathologic detection was 84.4%(1-8/128).11 cases (8.6%) were neglected and 9 cases were misdiagnosed by CT scanning.The detectable rates of tumescent lymph node of shorter than 1 cm and of longer than 1 cm were 23.1% and 76.9% respectively.The rates of sensitivity and specificity in CT scanning were 84.8%(167/197) and 87.5%(98/112).Conclusion With water as a contrast medium,CT scanning with water infused cradle can greatly improve the accuracy of the preoperative stage dividing and it has more superiority in observing the relationship between tumors and their peripheral organs and the tumesecnt lymph node.
