食管癌淋巴结转移影像诊断方法及进展

综述了目前诊断食管癌淋巴结转移的各种影像检查方法的诊断标准及诊断准确性，并对其准确性进行了比较。总体而言CT诊断的准确性较低，超顺磁性氧化铁（SPIO）微粒增强磁共振成像（MRI）诊断的准确性较高。各种检查方法都对小淋巴结转移的诊断能力有限。超声内镜（EUS）对纵隔淋巴结转移诊断的灵敏度较高，正电子发射计算机断层成像（PET—CT）对于远处淋巴结转移诊断的灵敏度高。

Imaging diagnosis methods and progress for lymph node metastasis in esophageal carcinoma

The article focuses on diagnostic criteria and diagnostic accuracy of the various imaging methods by lymph node metastasis in esophageal carcinoma at present, and compares accuracy of the various imaging methods. In general, the diagnostic accuracy of CT is lower, the diagnostic accuracy of uhrasmall superparamagnetic iron oxide-enhanced MR imaging is higher. Each imaging method has the lower accuracy for the diagnosis of smaller lymph node metastasis. Diagnostic accuracy of endoscopic ultrasonography is higher in the diagnosis of mediastinal lymph node metastasis. Sensitivity of PET/CT is higher for the diagnosis of distant lymph node metastasis.
