“…Though MR imaging with heavily T2-weighted MR images has already been used for the morphological diagnosis of lymphedema, analysis of lymphatic vessels has not yet been performed (10,(17)(18)(19).…”

PurposeThe purpose of the present study was to analyze the performances of non-contrast MR lymphography for the classification of primary lower limb lymphedema in 121 consecutive patients with 187 primary lower limb lymphedemas. Materials and methods121 consecutive patients with clinically diagnosed primary lower limb lymphedema underwent non-contrast MR lymphography with a free-breathing 3D fast spin-echo sequence with a very long TR/TE (4000/884 ms). MR examinations were retrospectively reviewed for severity of lymphedema (absent, mild, moderate, severe) and characteristics of inguinal lymph nodes and iliac and inguinal lymphatic trunks graded as aplasic (no lymph nodes or lymphatic trunks), hypoplasic (less lymph nodes or lymphatic trunks), normal and hyperplasic (more lymph nodes or more and/or dilated trunks). ResultsThere was an excellent correlation between clinical stage and severity of lymphedema (Cramer's V of 0,73 (p<0.001)). Differentiation was feasible between inguinal lymphatic vessel aplasia (21%), hypoplasia (15%), normal pattern (53%) and hyperplasia (11%).Severe lymphedema was observed in 46% of aplasic patterns and in 37% of hyperplasic patterns, but in only 15% of hypoplasic patterns and never observed in normal patterns (p<0.001). ConclusionNon-contrast MR lymphography is able to classify primary lower limb lymphedemas into hyperplasic, aplasic, hypoplasic and normal patterns.

“…A recent study compared IRL with magnetic resonance lymphangiography (MRL). 5 MRL was found to be more sensitive and accurate than lymphoscintigraphy in the detection of anatomical and functional abnormalities in the lymphatic system in patients with extremity lymphedema. 6 Mixed forms of lymphedema are best diagnosed with axial T2-weighted fat-suppressed (SPIR) sequences in conjunction with coronal T1 spin echo (SE) magnetic resonance imaging (MRI) sequences.…”

“…Although it is generally difficult to differentiate primary from secondary lymphedema, MRI is able to discriminate lymphedema from lipoedema and phlebedema (Lohrmann et al, 2009;Aström et al, 2001). Our standard procedure for pre-operative patients is an MRI with Gadolinium.…”
