发布时间:2020-10-28 07:38
目的:评估多层螺旋CT(Multi slice computed tomography,MSCT)对进展期胃癌Lauren分型的应用价值。方法:回顾性分析114例经手术病理证实的进展期胃癌的MSCT影像学表现,以Lauren分型标准分为肠型胃癌和弥漫型胃癌两组,比较两组进展期胃癌的肿瘤厚度、长径、门脉期CT值、强化方式、肿瘤表面有无溃疡情况、淋巴结分期。结果:肠型和弥漫型胃癌分别为50例和64例,两组厚度分别为(18.42±7.40)mm和(17.17±5.14)mm,差异无统计学意义(t=1.07,P=0.29);长径分别为(50.70±17.29)mm和(60.82±23.33)mm;门脉期CT值(黏液腺癌除外)分别为(75.75±15.81)HU和(85.80±18.17)HU;强化方式:(均匀∶不均匀=27∶23和21∶43);表面情况:(平坦∶溃疡=13∶37和32∶32);以上差异均有统计学意义,分别为(t=-2.57,P=0.01),(t=-3.05,P=0.00),(χ~2=5.17,P=0.02),(χ~2=6.77,P=0.01);淋巴结分期与病理对照符合率分别为84.00%与81.25%。结论:MSCT对进展期胃癌的Lauren分型有较大价值,两型进展期胃癌在肿瘤长径、门脉期CT值(黏液腺癌除外)、强化方式及肿瘤表面有无溃疡方面均有较大差异,CT对胃癌淋巴结分期有较高符合率。
