摘要:
目的是随着经导管的动脉化疗栓塞、(TACE)疗法治疗肝癌的广泛应用,碘油在CT、MRI检查中的信号表现受人关注,肝癌栓塞剂碘油的MRI特性仍存在着争议。碘油在病灶部位沉积的量,随时间变化,并与疗效密切相关,所以确立诊断,观察疗效就要有统一的检查时间和手段。材料和方法:回顾TACE术后的影像资料,复习文献。对碘油分布的形态进行统计,与疗效的统计进行比较。以CT表现为金标准。结果:我们认为分4型较好,1、稀少型,累计病灶内碘油沉积面积少于30%者列为稀少型,不再细分,并尽快改用其它的治疗肝癌的方法,因为,这型的TACE治疗效果不佳,不必第二次用TACE,再去分型也就没有实际意义了。2、均匀型,整个病灶均匀摄取碘油。3、缺损型,包括环型和某一区域沉积等情况。4、簇集型,碘油呈小簇状分散型分布,但肿瘤内碘油潴留累计不少于30%。结论:关于肝癌TACE后碘油沉积形态的CT分型,说法不一。需要进一步探讨统一。
Abstract:
Purpose: It has been reported that typing was chaotic after Intra-arterial Infusion of Iodized Oil, grouping is need scary to unification. Materials and Methods: On the basis of shape of sediment the patients after TACE were separated four group. A: Rare group. B: Full mass group. C: Gappy mass group. D: Clustered group. Previous studies have shown it is futile that sediment under 30% of area, do without typing again. Results: Full mass group produce a good curative effect. Gappy mass and clustered group take effect. Rare group is futile. Conclusion: It is concluded that sediment grouping in the shape was useful for evaluate the effect of TACE for HCC.
