基于MR-T2WI影像组学对结直肠癌淋巴结转移的诊断价值

基于MR-T2WI影像组学对结直肠癌淋巴结转移的诊断价值摘要：目的：探究MR-T2WI影像组学对结直肠癌淋巴结转移的诊断价值。方法：选取结直肠癌患者108例，分为淋巴结转移组和非淋巴结转移组。对患者进行MR-T2WI影像检查，提取图像特征，建立深度学习模型进行诊断，比较两组患者的深度学习模型指标。结果：MR-T2WI影像组学对结直肠癌淋巴结转移的诊断价值较高，与实验结果相比，假阳性率（FP）91.67％，假阴性率（FN）9.24％，准确率（ACC）94.44％，灵敏度（SEN）90.76％，特异度（SPE）87.6％，AUC值为0.935。结论：MR-T2WI影像组学诊断结直肠癌淋巴结转移是一种可靠的方法，可以为患者的治疗和预后提供有力支持。
