摘　　要：目的 探讨口服碘番酸造影CT诊断胆囊息肉样病变和阴性结石的价值。方法 回顾性分析我院经病理证实的18例胆囊息肉样病变和7例阴性结石的口服胆囊造影CT表现。结果 胆固醇息肉8例，表现为胆囊内多发或单发颗粒状充盈缺损，直径较小，为0．2～0．5cm；炎症性息肉4例，表现为带蒂或无蒂的点状或细条状充盈缺损，直径为0．5～1．5cm；腺瘤样息肉5例，表现为单发结节状充盈缺损，直径0．6～0．9cm；腺瘤恶变1例，表现为体积较大，基底部较宽的结节，直径2．0cm；阴性结石7例，表现为单发或多发大小不一的类圆形低密度影，CT值-120～13Hu．直径0．5～3．0cm。结论 口服胆囊造影CT是诊断胆囊息肉样病变和阴性结石的可靠方法之一，病变大小对病变的性质诊断有较大的帮助。Objective To investigate the diagnostic value of CT in patients with gallbladder polypi or negative stones by oral cholecystography. Methods Reviewed and analyzed the CT manifestation of oral cholecystography in patients with gallbladder polypi （ n = 18 ） or negative stones （ n = 7 ）, which had been proved by pa- thology. Results Cholestorol polypi （ n = 8 ） manifested as solitary or multiple granuler filling defects, whose diameter was 0.2 - 0.5cm. Inflammatory polypi （ n = 4） manifested as pedunculated or not, point or strip filling defects,whose diametev was 0.5 - 1.5cm. Adenoma polypi （n = 5 ）manifested as solitary nodular type filling defects,whose diameter was 0.6 ～0.9cm. Malignant adenoma（ n = 1 ） manifested as wide mode in basal part, whose diameter was 2.0cm. Negative stones（ n =7 ）manifested as solitary or multiple round lide low dense i- magine, whose CT value was - 120 ～ 13 Hu, and the diameter was 0.5 ～ 3.0cm. Conclusion Oral gallbladder cholecystography CT is one of the available mehods which can diagnose gallbladder polypi or negative stone, thesize of pathologic change has great help to the character.
