| 目的 评价比较多排螺旋CT分期扫描对胃癌术前T分期诊断的准确性。方法 对58例临床确诊为胃癌的住院患者进行术前16排螺旋CT两次给药三期扫描,并根据MSCT结果作出T分期诊断。所有病人手术后,取病理并进一步进行病理TNM分期。对各相扫描结果组合后诊断的结果的准确率进行对比。结果 MSCT三相扫描对胃癌术前分期的总准确度为77.59%,第1期+第2期扫描分期诊断准确率为60.34%,第2期+第3期扫描分期诊断准确率为75.86%,仅第3期(延迟期)扫描分期诊断准确率为75.86%。结论 多排螺旋CT两次给药延迟期扫描对胃癌术前T分期诊断有重要的临床价值。 |

| Objective To evaluate the accuracy of the preoperative staging of gastric cancer by the special scanning method of multiple detector-row spiral CT (adphasic scanning after twice administration). Methods Triphasic scanning of MSCT was performed in 58 patients with gastric cancer. Findings at every phasic scanning of MSCT were composed and compared with the post-operative histopathological results. Results Accuracy of the preoperative staging of advanced gastric cancer by triphasic scanning of MSCT was 77.59%.Accuracy of the first phasic scanning+the second phasic scanning, the second phasic scanning+the third phasic scanning and only the third phasic scanning were 60.34%, 75.86%, 75.86% respectively. Conclusion The special scanning of MSCT (adphasic scanning after twice administration) is effective and valuable for detection of gastric cancer and preoperative staging. |
