Lower cost ultrasound beats gold standard in assessment of psoriatic arthritis

February 26, 2008 Lower cost ultrasound beats gold standard in assessment of psoriatic arthritis Wendy Despain -------------------------------------------------------------------------------- Standard musculoskeletal ultrasound is better than gold standard radiography at detecting overall joint pathology in the hands and feet of patients with psoriatic arthritis. MR imaging showed marginally better sensitivity at detecting joint effusions and synovitis, while radiography detected more erosions in the joints.
