A total of 172 patients with monoclonal gammopathy of undetermined significance (MGUS) (<jats:italic>n<\/jats:italic>=17), smoldering MM (<jats:italic>n<\/jats:italic>=47) and symptomatic MM (<jats:italic>n<\/jats:italic>=108) underwent low-dose MDCT. CT values (CTv) of medullary density of AS\u2a7e0 Hounsfield unit (HU) was considered as abnormal. Percentage of medullary abnormalities and the mean CTv of AS in patients with MGUS, smoldering MM and symptomatic MM were 18, 55 and 62% and \u221244.5\u2009, \u221220.3 and 11.2\u2009HU, respectively (<jats:italic>P<\/jats:italic>&lt;0.001 and <jats:italic>P<\/jats:italic>&lt;0.001). Disease progression of MM was independently associated with high CTv on multivariate analysis. In symptomatic MM, the presence of abnormal medullary lesions was associated with increased incidence of high-risk cytogenetic abnormalities (34.4% vs 7.7%; <jats:italic>P<\/jats:italic>=0.002) and extramedullary disease (10.4% vs 0%; <jats:italic>P<\/jats:italic>=0.032). It was also an independent poor prognostic predictor (hazard ratio 3.546, <jats:italic>P<\/jats:italic>=0.04). This study showed that CTv of AS by MDCT is correlated with disease progression of MM, and the presence of abnormal medullary lesions is a predictor for poor survival.<\/jats:p>","DOI":"10.1038\/bcj.2015.57","type":"journal-article","created":{"date-parts":[[2015,7,31]],"date-time":"2015-07-31T13:21:22Z","timestamp":1438348882000},"page":"e329-e329","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Clinical and prognostic significance of bone marrow abnormalities in the appendicular skeleton detected by low-dose whole-body multidetector computed tomography in patients with multiple myeloma"],"prefix":"10.1038","volume":"5","author":[{"given":"Y","family":"Nishida","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y","family":"Matsue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y","family":"Suehara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"Fukumoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Fujisawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Takeuchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E","family":"Ouchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K","family":"Matsue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2015,7,31]]},"reference":[{"key":"BFbcj201557_CR1","doi-asserted-by":"publisher","first-page":"89","DOI":"10.1016\/j.acra.2011.09.016","volume":"19","author":"D Spira","year":"2012","unstructured":"Spira D, Weisel K, Brodoefel H, Schulze M, Kaufmann S, Horger M .
