Texture analysis is a group of computational methods for evaluating the inhomogeneity among adjacent pixels or voxels.We investigated whether texture analysis applied to myocardial FDG uptake has diagnostic value in patients with CS.\nMethods Thirty-seven CS patients (CS group), and 52 patients who underwent FDG PET/CT to detect malignant tumors with any FDG cardiac uptake (non-CS group) were studied.A total of 36 texture features from the histogram, gray-level co-occurrence matrix (GLCM), gray-level run length matrix (GLRLM), gray-level zone size matrix (GLZSM) and neighborhood gray-level difference matrix (NGLDM), were computed using polar map images. First, the inter-operator and inter-scan reproducibility of the texture features of the CS group were evaluated. Then, texture features of the patients with CS were compared to those\nwithout CS lesions.\nResults Twenty-eight of the 36 texture features showed high inter-operator reproducibility with intraclass correlation coefficients (ICCs) over 0.80. In addition, 17 of the 36 showed high inter-scan reproducibility with ICCs over 0.80.\nThe SUVmax showed no difference between the CS and non-CS group [7.36 ± 2.77 vs. 8.78 ± 4.65, p = 0.45, area under the curve (AUC) = 0.60]. By contrast, 16 of the 36 texture features could distinguish CS from non-CS grsoup with AUC > 0.80. Multivariate logistic regression analysis after hierarchical clustering concluded that long-run emphasis (LRE; P = 0.0004) and short-run low gray-level emphasis (SRLGE; P = 0.016) were significant independent factors that could distinguish between the CS and non-CS groups. Specifically, LRE was significantly higher in CS than in non-CS (30.1 ± 25.4 vs. 11.4 ± 4.6, P < 0.0001), with high diagnostic ability (AUC = 0.91), and had high inter-operator reproducibility (ICC = 0.98).\nConclusions The texture analysis had high inter-operator and high inter-scan reproducibility. Some of texture features showed higher diagnostic value than SUVmax for CS diagnosis. Therefore, texture analysis may have a role in semi-automated systems for diagnosing CS.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"30327855","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00259-018-4195-9","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://link.springer.com/article/10.1007%2Fs00259-018-4195-9","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1619-7070","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Manabe, Osamu"}],"nameIdentifiers":[{"nameIdentifier":"870223","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohira, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"870224","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirata, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"870225","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hayashi, Souichiro"}],"nameIdentifiers":[{"nameIdentifier":"870226","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Naya, Masanao"}],"nameIdentifiers":[{"nameIdentifier":"870227","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsujino, Ichizo"}],"nameIdentifiers":[{"nameIdentifier":"870228","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aikawa, Tadao"}],"nameIdentifiers":[{"nameIdentifier":"870229","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koyanagawa, kazuhiro"}],"nameIdentifiers":[{"nameIdentifier":"870230","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Noriko, Oyama-Manabe"}],"nameIdentifiers":[{"nameIdentifier":"870231","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tomiyama, Yuuki"}],"nameIdentifiers":[{"nameIdentifier":"870232","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Magota, Keiichi"}],"nameIdentifiers":[{"nameIdentifier":"870233","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinaga, Keiichiro"}],"nameIdentifiers":[{"nameIdentifier":"870234","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamaki, Nagara"}],"nameIdentifiers":[{"nameIdentifier":"870235","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinaga, Keiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"870236","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Use of ¹⁸F-FDG PET/CT texture analysis to diagnose cardiac sarcoidosis","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Use of ¹⁸F-FDG PET/CT texture analysis to diagnose cardiac sarcoidosis"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-23"},"publish_date":"2018-10-23","publish_status":"0","recid":"73846","relation_version_is_last":true,"title":["Use of ¹⁸F-FDG PET/CT texture analysis to diagnose cardiac sarcoidosis"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:52:54.252173+00:00"}
