螺旋CT胃黏膜成像技术对诊断早期胃癌的临床研究

Clinical Study of Spiral CT Gastric Mucosal Imaging Technique in the Diagnosis of Early Gastric Cancer

目的:探索改良螺旋CT胃黏膜成像技术扫描方案:动脉期中期(25s)、对比剂剂量80ml、对比剂注射速度3ml/s扫描(以下称改良螺旋CT扫描方案)对早期胃癌诊断的特异性及敏感性。方法:选择60例上腹部螺旋CT增强的病人进行分组对比研究,随机60人分为两组,每组30人,第一组应用改良螺旋CT扫描方案扫描,第二组进行胃镜检查,对比两组的准确性,探索改良螺旋CT扫描方案对早期胃癌诊断的特异性及敏感性。结果:改良螺旋CT扫描方案对早期胃癌诊断的正确性较胃镜检查高(螺旋CT93.33%,胃镜80%),对比有统计学意义(P<0.05)。结论:预期新技术在早期胃癌诊断方面将具有重要临床价值。

Objective:To explore the scanning scheme of modified spiral CT gastric mucosal imaging technology:The specificity and sensitivity of middle arterial phase (25s),80ml contrast dose and 3ml/s contrast injection rate (hereinafter referred to as modified spiral CT scanning scheme) in the diagnosis of early gastric cancer.Methods:60 patients with enhanced spiral CT of the upper abdomen were selected for a group comparison study,and 60 patients were randomly divided into two groups of 30 patients in each group.The first group was scanned with the modified spiral CT scanning scheme,and the second group underwent gastroscopy.Compared with the accuracy of the two groups by gastroscopy,so as to explore the specificity and sensitivity of the modified spiral CT scanning scheme in the diagnosis of early gastric cancer.Results:The accuracy of the modified spiral CT scanning scheme in the diagnosis of early gastric cancer was higher than that of gastroscopy (spiral ct 93.33%,gastroscopy 80%),and the comparison between the two methods was statistically significant ( P <0.05).Conclusion:Indicating that the new technique will have important clinical value in the diagnosis of early gastric cancer.
