摘要

目的探讨气体对比剂对于胃癌患者CT成像质量的应用价值。方法纳入303例胃癌患者，根据使用的对比剂将其分为气充盈组143例和水充盈组160例。由2名放射科医师独自评估患者轴位CT图像胃扩张充盈程度，对其进行主观评分分级，并比较2组患者图像质量评级。CT轴位测量胃底、胃体、胃窦正常胃壁厚度，比较2组患者正常胃壁厚度（＜5 mm）。结果 2名医师对水充盈组CT图像质量评级的一致性检验Kappa值为0.71，气充盈组为0.78。气充盈组轴位CT图像质量评级明显优于水充盈组（Z=-8.979，P＜0.001）；2组胃底、胃体及胃窦正常胃壁厚度（＜5 mm）比较，差异具有统计学意义（P＜0.001）。结论相对于水对比剂，气体对比剂充盈胃腔图像质量更佳，尤其对胃窦充盈效果优势更明显，可广泛应用于临床。
