The Clinical Applications of CT Cholecystography

目的 探讨胆囊造影CT对胆囊等或低密度结石、小息肉样病变的诊断价值。材料与方法 分析 3 0例由造影CT诊断并经手术病理证实的胆囊等或低密度结石 2 1例 ,小息肉样病变 9例。结果 常规CT对 15例等密度结石全部漏诊 ,6例低密度结石4例漏诊 ,9例小息肉样病变 6例漏诊 ,而造影CT对 3 0例全部确诊。结论 造影CT对胆囊等或低密度结石、小息肉样病变有很大的诊断价值 ,弥补了常规CT的不足。

Objective To evaluate CT cholecystography in diagnosing iso or hypo density calculi and small polypoid lesions of the gallbladder.Materials and Methods CT cholecystography findings in 21 pathologically proved cases with iso or hypo density calculi or with small polypoid lesions were retrospectively analyzed.Results All lesions were revealed on CT cholecystography, while on conventional CT scans missed diagnosis occurred in 19/21 cases with calculi and 6/9 cases with polypoid lesions.Conclusion CT cholecystography is superior to conventional CT scan in demonstrating the iso or hypo density calculi and small polypoid lesions of the gallbladder.
