MRI and FDG-PET/CT based assessment of axillary lymph node metastasis in early breast cancer: a meta-analysis

The present meta-analysis suggests that MRI not only has the higher sensitivity for lymph node metastasis diagnosis compared to PET/CT, but also has high potential for being used as a non-invasive imaging diagnostic technique. Furthermore, the ultra-small super paramagnetic iron oxide (USPIO)-enhanced MRI showed high diagnostic accuracy for identifying axillary lymph node metastases in early-stage breast cancer patients.
