Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study proposes to establish an image feature extraction and selection method for identifying lymph node metastasis of esophageal cancer.The study will consider the relationship between the main lesion and the suspected lymph node, extract association characteristics in order to improve the sensitivity and specificity of the CT radiomics-based prediction model for identifying metastasis lymph nodes. The study includes the construction of CT radiomics-based prediction model and the validation of the prediction model.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

preoperative enhanced chest CT

The cohort contains patients with preoperative therapies and patients without preoperative therapies. Each patient receives regular preoperative enhanced chest CT; for patients with preoperative therapies, they usually undergo twice enhanced chest CT examination at before and after preoperative therapies, the CT images after preoperative therapies will be used for analysis
