This study was carried out to study multi-slice spiral CT imaging for patients with gastric carcinoma and explore the values of multi-slice spiral CT imaging in staging prior to gastric carcinoma (GC) surgery. Forty-eight patients with GC underwent multi-slice spiral CT, and the scanning results were compared with the pathological results. The similarity of the results was observed, and the accuracy was calculated. Of 48 patients, 8 did not undergo surgery because of metastasis. In the diagnosis of the remaining 40 patients, the sensitivity of multi-slice spiral CT in the diagnosis of staging of invasive depth of GC was 77.5%; κ = 0.642 in the analysis of consistency; there was no significant difference with the pathological results (p >0.05). The overall accuracy of diagnosis for stage N was 80%. The accuracy of multi-slice CT in detecting distant metastasis of GC was 87.5%. Multi-slice spiral CT can determine and evaluate various metastases of GC. The diagnostic results obtained using multi-slice spiral CT was probably consistent with the pathological results.
本研究旨在探讨多层螺旋 CT 成像对胃癌患者的应用价值，及其在胃癌（GC）术前分期中的作用。对 48 例胃癌患者行多层螺旋 CT 扫描，将扫描结果与病理结果进行对比，观察结果的相似性，并计算准确率。48 例患者中，8 例因转移未行手术。在对其余 40 例患者的诊断中，多层螺旋 CT 对 GC 浸润深度分期诊断的灵敏度为 77.5%；一致性分析中κ=0.642；与病理结果无显著差异（p＞0.05）。N 期的总体诊断准确率为 80%。多层 CT 对 GC 远处转移的检出率为 87.5%。多层螺旋 CT 可明确和评估 GC 的各种转移情况，诊断结果可能与病理结果一致。
