Material and methods: We enrolled 50 healthy volunteers (37 women, age between 30-58 years, mean age 41.7 years, divided into 3 groups according to age: 30-39, 40-49, and 50-58 years). The subjects were successively evaluated by 4 rheumatologists: 2 experienced (team A) and 2 beginners (team B) in US. Seven dorsal and palmar longitudinal scanning positions and a supplementary scan for MCP cartilage were performed. The bone surface (erosions, osteophytes), the intra-articular content (synovial thickening and vascularization, 4 grade scale), and the aspect of the metacarpal head cartilage were analyzed. The anterior palmar recess was measured. The time for examination was recorded. Results: Erosions were detected in 7% of joints by team A and 2% by team B (p&lt;0.05, kappa agreement 0.567) in subjects over 40 years. The agreement by team A in the detection of the erosions was very good (kappa value 0.83). A moderate positive correlation was obtained between the presence of erosions and age (r= 0.401, p=0.004). Osteophytes were identified only on the dorsal scan in subjects over 50 years (in 3.5% of joints team A, 1.5% team B, p&gt;0.05, kappa value 0.421). No grade 1 synovitis was observed by team A but 4 joints with grade 1 synovitis were identified by team B (p&lt;0.05) from the dorsal scan. The dimensions of the palmar recess had large distribution (MCP 2 between 0.55-1.3 mm; MCP 5 between 0.6-1.2 mm). No statistical significant differences were obtained when comparing the dimensions of the two hands, the values obtained in age-groups (all p&gt;0.05). No statistical significant correlations were obtained between the dimensions of palmar recess and the body mass index or dominant hand (all p&gt;0.05). No pathological findings were found in the examination of the metacarpal head cartilage. Power Doppler investigation found the presence of grade 1 signal in 2.5% joints by team A and 1.5% by team B (p&gt;0.05) only in the dorsal scans. The mean time for examination was 7.8\u00b11.74 min in team A and 13.78\u00b12.96 min in team B (p&lt;0.05). Conclusions: In healthy subjects pathological findings are occasionally encountered, especially erosions and osteophytes. Using an 18 MHz transducer the aspect of grade 1 synovitis was not encountered in healthy non-inflammatory MCP joints. There is a permanent need for standardized training and examination in musculoskeletal US.<\/jats:p>","DOI":"10.11152\/mu.2013.2066.172.mcph","type":"journal-article","created":{"date-parts":[[2015,6,2]],"date-time":"2015-06-02T13:03:03Z","timestamp":1433250183000},"page":"185","source":"Crossref","is-referenced-by-count":11,"title":["Ultrasonography of the metacarpophalangeal joints in healthy subjects using an 18 MHz transducer."],"prefix":"10.11152","volume":"17","author":[{"given":"Daniela","family":"Fodor","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ioana","family":"Felea","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniela","family":"Popescu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adelina","family":"Mo\u0163ei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula","family":"Ene","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oana","family":"\u015eerban","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihaela","family":"Micu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4840","published-online":{"date-parts":[[2015,6,1]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"http:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/794\/774","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/794\/774","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,12,13]],"date-time":"2016-12-13T16:35:00Z","timestamp":1481646900000},"score":1,"resource":{"primary":{"URL":"http:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/794"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,6,1]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2015,6,1]]}},"URL":"https:\/\/doi.org\/10.11152\/mu.2013.2066.172.mcph","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2015,6,1]]}}}
