Improved Esophageal Cancer Response Assessment with Early Contrast-Enhanced MRI

Early contrast-enhanced MR imaging showed higher accuracy in detecting complete tumor response in esophageal squamous cell carcinoma post-neoadjuvant therapy compared to T2WI+DWI. ECE-MRI had an AUC of 0.85 for diagnosing ypt1-4, significantly better than T2WI+DWI. Performance improved with increasing tumor stage, with higher AUCs in ypt1 and ypt2 tumors. ECE-MRI visual evaluation is promising for accurate diagnosis, aiding in individualized treatment decisions for patients.
