Motivation: Lymph node metastasis of rectal cancer reflects tumor invasiveness and recurrence risk, primarily evaluated by MRI. Goal(s): This study aims to enhance the diagnostic capabilities of MRI in rectal cancer by assessing the diagnostic value and potential application of the T2 mapping sequence for determining lymph node metastasis. Approach: Data were collected from patients with pathologically confirmed rectal cancer, and parameters derived from the T2 mapping sequence were analyzed to identify differences associated with lymph node metastasis. Results: The parameters obtained from T2 mapping demonstrate strong predictive potential for lymph node metastasis in rectal cancer. Impact: This study demonstrated that the T2 mapping sequence has significant diagnostic value in evaluating lymph node metastasis in rectal cancer. This non-invasive approach facilitates improved differentiation of lymph node metastasis of rectal cancer, thereby enhancing rectal cancer treatment management.
