Validity of Ultrasound Imaging in Measuring Quadriceps Muscle Thickness and Cross‐Sectional Area in Patients Receiving Maintenance Hemodialysis

Muscle wasting, prevalent in maintenance hemodialysis (HD) patients diagnosed with protein-energy wasting, represents an assessment challenge in the outpatient HD setting. Quadriceps muscle thickness (QMT) and cross-sectional area (CSA) assessment by ultrasound (US) is a potential surrogate measure for muscle wasting. We aimed to determine the validity of US to measure QMT and CSA against the gold standard-computed tomography (CT).Twenty-six...
