  "statement": "In a systematic review of 32 studies (1154 patients), imaging methods proposed for characterizing lipedema include ultrasound (increased subcutaneous adipose tissue), lymphoscintigraphy (slowed lymphatic flow, inter-limb asymmetry), CT (symmetrical bilateral soft tissue enlargement without skin thickening or edema), MRI, MR lymphangiography (enlarged lymphatic vessels up to 2 mm), and DXA (leg fat mass/BMI ≥0.46 or leg fat/total fat ≥0.384), but their overall diagnostic performance was limited.",
