We determined the anatomic features and best imaging techniques of normal PTT and PBT using musculoskeletal ultrasound and compared these findings to subjects with inflammatory arthritis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Adult subjects were enrolled as healthy controls (HCs), rheumatoid arthritis (RA) patients, or spondyloarthropathy (SpA) patients. Bilateral PTT and PBT entheses were imaged longitudinally, comparing 2 angles of insonation: perpendicular to the skin surface and 45\u00b0 cephalad. Images were scored on semiquantitative scales assessing pathology.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 78 subjects were enrolled (37 HC, 21 RA, and 20 SpA). Complete enthesis visualization was achieved more frequently in the perpendicular than in the cephalad view for the PBT (76.3% versus 58.7%), but more frequently in the cephalad view for the PTT (58.0% versus 19.6%). RA and SpA subjects had higher rates of PTT fiber disruption (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), PTT tenosynovial effusion (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), and Doppler signal (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) than HCs. No significant differences existed at the PBT enthesis. In multivariate analysis, RA and SpA subjects were found to be 5.1 times (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) and 3.6 times (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) more likely to exhibit ultrasound\u2010detected pathology, respectively, than HCs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The perpendicular transducer aim is optimal for imaging the PBT, while the cephalad transducer orientation was more effective for evaluation of the PTT. Unlike distal PBT imaging, PTT imaging distinguished healthy and disease states, with both RA and SpA patients showing features of PTT enthesopathy. Distal PTT imaging is a useful technique for musculoskeletal ultrasound.<\/jats:p><\/jats:sec>","DOI":"10.1002\/acr.23180","type":"journal-article","created":{"date-parts":[[2016,12,20]],"date-time":"2016-12-20T17:12:44Z","timestamp":1482253964000},"page":"1519-1525","source":"Crossref","is-referenced-by-count":9,"title":["Ultrasound
