    ### Response:
    How is Madelung disease diagnosed? Madelung disease is usually diagnosed based on a thorough physical exam, accurate medical history, and imaging studies - computed tomography (CT scan) and/or magnetic resonance imaging (MRI scan). A CT scan is an imaging method that uses x-rays to create pictures of cross-sections of the body, while an MRI scan uses powerful magnets and radio waves to create pictures of the lipomas and surrounding tissues.
