In a systematic review of six diagnostic modalities, MRI/MRL achieved 100% sensitivity (calf subcutaneous water area) and reliably differentiated lymphedema from lipedema, with non-contrast MRL identifying increased subcutaneous adipose tissue in lipedema and epifascial collections in lipolymphedema; CT showed 95% sensitivity/100% specificity for lipedema with subcutaneous honeycombing being 100% specific for lymphedema and absent in lipedema; whereas lymphoscintigraphy (lymphedema gold standard) could NOT distinguish lipedema from lymphedema since lymphatic changes occur in both.

“Valores de corte de US para diagnóstico de lipedema: espessura dérmica de 8,4 mm (região lateral da perna), 11,7 mm (pré-tibial) e 17,9 mm (coxa) — valores reportados por estudo de 2021; lipedema associado a aumento de espessura de pele e hipoecogenicidade subcutânea”
Scoping review directly comparing MRI/MRL, lymphoscintigraphy, CT and other modalities for differentiating lipedema from lymphedema, reporting sensitivity/specificity and distinguishing features.
