Deep learning model shows promise in assessing lymph node metastasis

A deep learning model utilizing multi-parametric MRI sequences effectively identifies lymph node metastasis in rectal cancer preoperatively. In trials involving 613 patients, this model, incorporating T2-weighted imaging, diffusion-weighted imaging, and dynamic contrast-enhanced sequence, achieved an area under the curve (AUC) of 0.808 in internal tests and 0.782 in external tests, outperforming traditional imaging and radiologists. The multi-parametric approach signifies a potential advancement in automated diagnostic tools for clinical use.
