Non-contrast Magnetic Resonance Lymphangiography: an emerging technique for the study of lymphedema

Abstract

Lymphedema (LE) is a chronic disabling disease, characterized by the accumulation of macromolecules and liquids in the interstitial space. Patients affected by LE should undergo appropriate imaging to confirm the diagnosis, to evaluate characteristics and the severity of LE and to allow for correct management and treatment plan. However, there is no consensus regarding the best imaging technique to study this disorder. We want to propose an overview of the studies published on Non-contrast Magnetic Resonance Lymphangiography, a relatively new technique for the diagnosis, assessment and management of lymphedema.
