Muscle thickness (MT) and quantitative muscle echo intensity (EI) were assessed with QMUS in 4 muscles. <jats:italic>Results<\/jats:italic>: Six patients experienced a monocyclic course. At diagnosis EI was slightly increased, and MT was relatively normal. After start of treatment MT first decreased and EI increased, with normalization of EI within 6\u201312 months (<jats:italic>n<\/jats:italic>\u2009=\u20094). One patient had higher EIs at diagnosis and slower normalization, indicating fibrosis, despite early normalization of CMAS. One patient experienced a chronic course, with high EIs and atrophy during follow\u2010up. <jats:italic>Conclusions<\/jats:italic>: QMUS can provide additional information for follow\u2010up of JDM regarding disease severity and residual muscle damage, particularly after normalization of CMAS. <jats:italic>Muscle Nerve<\/jats:italic> 52: 540\u2013546, 2015<\/jats:p>","DOI":"10.1002\/mus.24564","type":"journal-article","created":{"date-parts":[[2014,12,31]],"date-time":"2014-12-31T05:06:01Z","timestamp":1420002361000},"page":"540-546","source":"Crossref","is-referenced-by-count":41,"title":["Quantitative muscle ultrasonography in the follow\u2010up of juvenile dermatomyositis"],"prefix":"10.1002","volume":"52","author":[{"given":"G.
