| 目的 前瞻性评价螺旋CT薄层增强扫描对胃癌术前分期的价值。方法 对103例胃癌进行低张水充盈螺旋CT增强扫描,延迟时间40s,层厚5mm,床速5mm/s,在工作站获得重建间隔2.5mm和多平面重建(MPR)图像。结果 胃癌TNM分期的准确性分别为76.8%、77.5%和94.2%。结论 螺旋CT薄层增强扫描和MPR技术可以提高胃癌浸润胃壁深度、淋巴结转移的敏感性,从而提高胃癌TNM分期的准确性。 |

| Purpose To evaluate the value of spiral CT with thin slice incremental scanning in the preoperative staging of gastric carcinoma. Methods One hundred and three patients with gastric carcinoma were preoperatively imaged by spiral CT using incremental scanning, hypotonia and water filling. Scans were started 40s after the initiation of the injection of the intravenous contrast material. Spiral CT was performed with 5mm slice thickness , 5mm/s table speed. Images reconstruction was performed at 2.5mm intervals and multiplanar reconstruction (MPR) was also performed at the CT console. Results T, N and M staging accuracies were 76.8%, 77.5% and 94.2%, respectively. Conclusion The sensitivity of depth of tumor invasion, lymph node metastase was improved by spiral CT using 5mm incremental scanning and MPR. Thereby the accuracy of TNM was improved. |
