  "statement": "Using 15 MHz cutaneous ultrasonography with computer-assisted (ImageJ) measurement of dermal echogenicity, lipedema was characterized by increased subcutaneous thickness and subcutaneous hypoechogenicity throughout the limb (subcutaneous echogenicity at calf ~60 vs 79 in lymphedema, p=0.005) and a preserved dermal:subcutaneous echogenicity ratio, distinguishing it from lymphedema which showed predominantly distal dermal thickening and dermal hypoechogenicity.",
