Magnetic resonance lymphangiography staging system for lower limb lymphedema. Presidential award proceedings

This retrospective study analyzed the magnetic resonance lymphography (MRL) findings of 112 lower limbs of 56 lymphedema patients, and identified characteristic patterns of lymphatic impairment that change with the location in lower limbs and clinical stage. The authors proposed an MRL staging system that enables a new patient stratification based on the severity of the lymphatic injury, thus potentially improving clinical management. (author)
