Objective: Musculoskeletal ultrasound has gained recognition in early identification of crystal deposits in the joints and soft tissues. This study aims to validate the sonographic features of 1st metatarsophalangeal joints (MTPJs) in gout and asymptomatic hyperuricemia (AH). Methods Patients with gout (n=20) and AH (n=16) underwent a gray-scale ultrasound assessment of both 1st MTPJs on 3 positions (dorsal, medial, plantar) in longitudinal view. The static images were read by 2 blinded trained sonologists for the presence of double contour sign (DCS), erosions, and tophi.
