目的评价多层螺旋CT及其后处理技术在诊断原发性十二指肠癌的价值。资料与方法对7例经手术后病理证实的原发性十二指肠癌患者的多层螺旋CT表现进行回顾性分析。结果7例中有4例表现为局部软组织肿块影;3例表现为管壁增厚和管腔狭窄;同时表现为局部软组织肿块和管壁增厚、局部管腔狭窄者2例;与胰头分界不清2例;肝内转移1例;肺内转移1例;增强扫描表现为软组织肿块者在动脉期有明显强化,静脉及延迟期强化部分消退明显。结论多层螺旋CT及其后处理技术对原发性十二指肠癌的诊断和手术分期及指导治疗有价值。
Objective To evaluate the value of multislice spiral CT and its post-processing in the diagnosis of primary duodenal cancer. Materials and Methods Retrospective analysis of 7 cases of primary duodenal cancer confirmed by pathology after operation. Results 4 of 7 cases showed local soft tissue mass, 3 cases showed wall thickening and stenosis, 2 cases of local soft tissue mass and wall thickening and local stenosis, 2 cases of indistinct demarcation, 1 case of intrahepatic metastasis and 1 case of intrapulmonary metastasis. Those with soft tissue masses showed enhanced enhancement in the arterial phase and obvious attenuation of the veins and delayed phases. Conclusion Multi-slice spiral CT and its post-processing techniques are valuable for the diagnosis, surgical staging and guiding treatment of primary duodenal cancer.
