目的 比较经直肠腔内超声（ERUS）与剪切波弹性成像（SWE）在直肠癌诊断中的应用价值。方法 选取我院经病理确诊的128例直肠肿瘤患者，其中直肠癌68例（恶性组），直肠腺瘤60例（良性组），两组均行ERUS和SWE检查，比较动脉血流阻力指数（RI）、搏动指数（PI）、收缩期血流峰值流速（PSV）、舒张末期血流速度（EDV）、杨氏模量均值（Emean）的差异。绘制受试者工作特征（ROC）曲线评估RI、PI、PSV、EDV、Emean对直肠癌的诊断效能。结果 恶性组RI、PI均低于良性组，PSV、EDV、Emean均高于良性组，差异均有统计学意义（均P＜0.05）。直肠癌T1、T2、T3、T4期RI、PI、PSV、EDV、Emean比较，差异均有...

Objective To compare the application value of endorectal ultrasound(ERUS)and shear wave elastography(SWE)in the diagnosis of rectal cancer.Methods A total of 128 patients with rectal tumor diagnosed by pathological biopsy in our hospital were selected,including 68 patients with rectal cancer(malignant group)and 60 patients with rectal adenoma(benign group).Both groups underwent ERUS and SWE examinations,the arterial blood flow resistance index(RI),pulsatility index(PI),peak systolic blood flow velocity(PSV),end-diastolic blood flow velocity(EDV)and Emean were compared.Receiver operating charac...
