Signature Analysis of Dynamic Enhanced CT for Gastrointestinal Carcinoid

  • 摘要: 目的:探讨胃肠道类癌动态增强CT影像学表现,旨在提高对该病的诊断水平。方法:回顾性分析11例胃肠道类癌患者的CT平扫及动态增强资料,对病变部位的肠壁厚度、边界、形态、周围毗邻结构情况、密度及动态增强特点进行评价;绘制ROC曲线评价远处转移的预测因素。结果:病变质地平扫CT值为26-48HU,平均为(33.54±6.96)HU;动脉期CT值为33-87HU,平均为(62.72±19.35)HU;门静脉期CT值为56-100HU平均(71.18±12.54)HU;延迟期CT值为43-78HU,平均为(60.09±12.69)HU。病变强化特点以渐进式强化为主,于门静脉期达到峰值,延迟期下降不明显,形成一个平台;病变管壁厚度对预测类癌远处转移有一定价值(AUC=0.917,<i<P</i<<0.05)。结论:动态增强CT扫描诊断胃肠道类癌具有应用价值。
    Abstract: Objective: To characterize the imaging findings of dynamic enhanced CT for gastrointestinal carcinoid, in order to improve the diognosis. Method: 11 patients with gastrointestinal carcinoid were retrospectively analyzed. The pathological changes of the cavity wall thickness, margin, morphology, adjacent structure, density and dynamic enhanced CT feature on three phases image were to evaluate. The ROC curve was used for finding prognostic factor of metastasis. Result: The attenuation of lesions in the plain scan was(33.54 ± 6.96)HU(range 26 - 48 HU),(62.72 ± 19.35)HU(range 33 - 87 HU) in the arterial phase, 56 - 100 HU(range 56 - 100 HU) in the venous phase,(60.09 ± 12.69)HU(range 43 - 78 HU) in the lag period. The lesions slowly enhanced, the density was to the peak in portal vein phase. The lesions density in delay phase was to lower, forming a plateau. Lesions in the cavity wall thickness had certain value in predicting carcinoid tumor distant metastasis(AUC = 0.917, <i<P</i<<0.05). Conclusion: Dynamic enhanced CT had clinical application value in diagnosis of gastrointestinal carcinoid.
