MRL as one-shot examination for patients suffering from lymphedema.

MR lymphangiography (MRL) is an emerging technique focalized on a noninvasive or minimally invasive imaging of lymphatics with the goal to treat and plan lymphedema. Doctor Cellina M. and colleagues clearly underlined the possible role of MRL with volume calculation as an objective mark also in evaluating response to treatment. In this Letter to the Editor, we would like to highlight the rising role of MRL, pointing out the advantages of both the non-contrast and contrast-enhanced approach, in lymphatic vessels study.
