目的探讨多层螺旋CT增强扫描在原发性十二指肠癌诊断中的应用价值.方法回顾性分析19例经手术、病理证实的原发性十二指肠癌患者的多层螺旋CT影像学资料.结果 19例中手术组15例,非手术组4例.CT表现为局部软组织肿块影8例,表现为管壁增厚和管腔狭窄5例,二者都有6例.双期增强扫描表现为十二指肠肿瘤静脉强化程度较动脉期强化明显.肿瘤不能切除的CT征象:肿瘤直径＞6 cm;腹腔、系膜淋巴结成团肿大；腔静脉、肠系膜动静脉等重要血管管径被包绕＞ 2/3.结论原发性十二指肠癌的多层螺旋CT增强扫描有助于术前可切除性评价.

Objective To investigate the clinical value of multi-slice spiral CT (MSCT) in diagnosing primary duodenum carcinoma.Methods The MSCT findings of 19 patients with primary duodenum carcinoma proved by operation and pathology were retrospectively analyzed.Results Among the 19 cases,15 cases were in surgical group,4 cases were in unresectable group.Eight cases showed local masses.Five cases manifested ductal wall narrowing or circular thickening.Six cases showed both features of local masses and dutal wall thickening.Dual phase enhancement showed the enhanced Hounsfield' s units of the masses in portal-phase(PP) were higher than that in the arterial-phase (AP).The unresectable sign of the local malignancies included local mass with a diameter more than 6 cm,periportal or perimesenteric lymphadenopathy.More than two-third invation of vital structures such as SMA,IVC,etc.Conclusions MSCT enhanced scans is helpful for the preoperative resectability evaluation of primary duodenum carcinoma.
