Prospective collection uses a Philips 3.0T MRI scanner equipped with a dStream Torso 32-channel coil. DCE-MRI was performed using a free respiration sequence with a flow rate of 3.0 m/s. The medical images and clinical data related to esophageal cancer using 4D Free Breathing DCE-MRI technology were performed by two radiologists (one with 3 years of diagnostic experience and the other with 15 years of diagnostic experience), including subjective and objective assessment of image quality in the diagnosis of esophageal cancer, and the use of this technology to predict the efficacy of preoperative neoadjuvant chemoradiotherapy for esophageal cancer with pathological PCR as the outcome.
