| 目的 探讨低张充气多层面CT三期增强扫描对胃肠道淋巴瘤与癌诊断与鉴别诊断的价值。 方法 对17例胃肠道淋巴瘤、30例胃肠癌患者行低张充气16层螺旋CT三期增强扫描并进行后处理观察,对比分析其相关CT表现。 结果 与胃肠癌相比,淋巴瘤累及胃肠的范围较癌广泛,病变段外缘光滑、自然,相邻脂肪间隙清晰,在低张充气的情况下,淋巴瘤病变段胃肠腔窄而不闭或扩张,76.47％病变与相邻胃肠壁无截然分界,病变腔面线样强化的黏膜与相邻胃肠黏膜相延续,可清楚显示淋巴瘤的黏膜下生长特点。 结论 胃肠低张充气MSCT对比剂增强三期扫描结合后处理技术可对胃肠道肿瘤及时发现、鉴别诊断提供更多、更全面的信息,可反映胃肠肿瘤的病理特点,有助于胃肠淋巴瘤诊断。 |

| Objective To assess the findings and value of three-phase contrasted multi-slice computed tomography (MSCT) pneumocolon or pneumogasric for patients with gastrointestinal lymphoma and carcinoma. Methods Seventeen patients with gastrointestinal lymphoma and thirty patients with gastrointestinal carcinoma underwent three-phase contrasted abdominal MSCT examination with pneumocolon or pneumogasric and corresponding post-procession. Results Compared with gastrointestinal carcinoma, gastrointestinal lymphoma appears wider diffusion infiltration with preservation of fat planes, stomach remains pliable,and lumen is narrow but preserved or aneurysmal dilation. Unclear margins with surround gastrointestinal wall has been noted in 76.47％ patients with gastrointestinal lymphoma, line enhancement mucous transfering from thickening wall to surround gastrointestinal wall suggest submucosa infiltration. Conclusion Multi-phase contrasted MSCT pneumocolon or pneumogasric and its post-procession can provide more and reliable information in detection and differential diagnosis of gastrointestinal neoplasm. Imaging appearance which can reflect pathological feature is helpful in diagnosis of gastrointestinal lymphoma. |
