This study evaluated a radiological nodal staging metric for accurate identification of diseased axillary lymph nodes (aLNs) on MRI associated with breast cancer. Comparison was made with pathological nodal staging as the ground truth. Radiological scoring of aLNs identifies diseased nodes as suspicious more correctly than it identifies normal nodes as normal. Overall, radiological scoring of the axillary lymph nodes based on morphological characteristics showed moderate accuracy in distinguishing disease or no-disease in the nodes based on standard clinical breast MRI data. Improvement in image signal-noise-ratio (SNR), spatial resolution and contrast of the axillary lymph nodes is needed.
