Quantitative measurements of gray-scale US images were performed using the histogram software of the scanner. The histogram ratios of the parotid glands from both sides were obtained (histogram ratio; mean gray-scale histogram parotid\/mean gray-scale histogram fat). Strain ratio (SR; ratio of fat to gland parenchyma) was calculated from the color-coded images. Subjective B-mode US scoring of electronically recorded gray- scale US images was performed by two radiologists independently for intra- and inter-observer agreement. Subjective assessments, quantitative measurements, and clinical parameters were compared.\r\nResults: The SR of the patient group (1.4\u00b10.8 right side, 1.5\u00b10.9 left side) was significantly higher than that of the control group (1.0\u00b10.3 right side, 1.1\u00b10.3 left side) (p<\/jats:p>","DOI":"10.5606\/archrheumatol.2019.7120","type":"journal-article","created":{"date-parts":[[2020,1,29]],"date-time":"2020-01-29T02:00:53Z","timestamp":1580263253000},"page":"371-379","source":"Crossref","is-referenced-by-count":13,"title":["The Role of Real-Time Tissue Elastography and Gray-Scale Ultrasound Histogram Analysis in the Diagnosis of Patients With Sj\u00f6gren\u2019s Syndrome"],"prefix":"10.5152","volume":"34","author":[{"family":"\u0130lhan SEZER","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"\u0130clal ERDEM TOSLAK","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Buket YA\u011eCI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Funda ERBASAN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Ay\u015fe AYAN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"U\u011fur KARASU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3111","published-online":{"date-parts":[[2019,12,31]]},"container-title":["Archives of Rheumatology"],"original-title":[],"link":[{"URL":"https:\/\/archivesofrheumatology.org\/index.php\/pub\/article\/download\/1039\/1772","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/archivesofrheumatology.org\/index.php\/pub\/article\/download\/1039\/1773","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/archivesofrheumatology.org\/index.php\/pub\/article\/download\/1039\/1772","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,23]],"date-time":"2025-10-23T10:34:53Z","timestamp":1761215693000},"score":1,"resource":{"primary":{"URL":"https:\/\/archivesofrheumatology.org\/index.php\/pub\/article\/view\/1039"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12,31]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2019,12,31]]}},"URL":"https:\/\/doi.org\/10.5606\/archrheumatol.2019.7120","relation":{},"ISSN":["2618-6500"],"issn-type":[{"value":"2618-6500","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,12,31]]}}}
