摘要目的探讨MDCT术前纹理分析与胃癌病人总生存期的相关性。方法伦理委员会批准并签署知情同意书。56例经活检证实的胃癌病人行MDCT检查,并经手术治疗。使用经过滤过或没有滤过的粗细纹理对纹理分析的影像特征进行量化。使用Kaplan-Meier和Cox分析法评估与生存时间的相关性。结果根据不同的阈值,以下参数均与预后不良有
Abstract Objective To investigate the correlation between the pre-MDCT texture analysis and the overall survival of patients with gastric cancer. Method ethics committee approves and signs informed consent. 56 cases of biopsy confirmed gastric cancer patients MDCT examination, and after surgery. The texture features of the texture analysis are quantified using either filtered or unfiltered texture. Kaplan-Meier and Cox analyzes were used to assess the association with survival time. The results according to different thresholds, the following parameters are associated with poor prognosis
