A T2 high-signal line between the fragment and its bed on MRI is known as a reliable indicator of an unstable lesion. However, the lesion exhibits various conditions even if a T2 high-signal line is observed. The purpose of this study was to evaluate the relationship between the T2 value of a high-signal line and the condition of the area between the fragment and its bed in OLT.    Methods:  T2 values of the T2 high-signal line and those of joint fluid were measured from preoperative MRI images in 46 ankles with OLT and the T2 ratio (high-signal line / joint fluid) was calculated. The relationship between the T2 ratio and CT, arthroscopic, and histologic findings was examined.    Results:  The mean T2 ratio was 0.48. T2 ratios of cystic lesions (0.62) or bone absorption (0.67) in the bed were significantly higher than those without a cyst (0.40) or no absorption (0.40). The T2 ratio of an unstable lesion (0.51) was significantly lower than that of a stable lesion (0.29). In histologic findings, there were 2 separate patterns: chondral and subchondral bone separations. The T2 ratio of the chondral separation (0.60) was significantly higher than that of bone separation (0.48).    Conclusion:  This study showed that the T2 ratio on a high-signal line was a predictor of stability, cyst, and bone absorption in OLT.    Level of evidence:  Level III, comparative series.","subitem_description_language":"en"},{"subitem_description":"アクセプト後にタイトル・アブストラクト等変更あり、著者最終稿は変更前のタイトル\"T2 value of high signal line on MRI is related to the conditions around the fragment in osteochondral lesion of talus\"","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"SAGE Publications"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1071-1007","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1944-7876","subitem_source_identifier_type":"ISSN"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"698"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2020-06-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicPageEnd":"704","bibliographicPageStart":"698","bibliographicVolumeNumber":"41","bibliographic_titles":[{"bibliographic_title":"Foot and Ankle International"},{"bibliographic_title":"Foot and Ankle International"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_b1a7d7d4d402bcce","subitem_version_type":"AO"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1177/1071100720910381","subitem_relation_type_select":"DOI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"32148074","subitem_relation_type_select":"PMID"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1177/1071100720910381","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"FootAnkleInt_41_698.pdf","filesize":[{"value":"877.8 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2006896/files/FootAnkleInt_41_698.pdf"},"version_id":"7982417a-1188-43c6-a6a5-78d57fd48c84"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"51081"},"item_title":"Relationship of T2 Value of High-signal Line on MRI to the Fragment in Osteochondral Lesion of the Talus","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2006896","relation_version_is_last":true,"title":["Relationship of T2 Value of High-signal Line on MRI to the Fragment in Osteochondral Lesion of the Talus"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T08:39:17.768488+00:00"}
