Intratendinous Power Doppler Changes Related to Patient Position in Seronegative Spondyloarthritis

摘要: Seronegative spondyloarthropathy (SpA) is a chronic inflammatory disease that includes heterogeneous group of diseases such as psoriatic arthritis (PsA), ankylosing spondylitis (AS), reactive arthritis, associated with bowel disease, and undifferentiated SpA. Enthesis tendon involvement are 2 important aspects SpA1. There strong evidence demonstrates the role ultrasound (US) power Doppler (PD) technique its higher sensitivity, compared to clinical examination, in detection signs entheseal both late early stages2. One main limits operator dependency. A minimal change transducer position or an erroneous setting can provide completely different information, easily leading misinterpretations. The importance patient’s during US assessment has not been well studied3,4. We investigated effect this phenomenon at enthesis levels 4 patients images were obtained MyLab 70 XVG system (Esaote Biomedica, Genoa, Italy) 6–18 MHz linear B-mode frequency 18 9.1 …
