This study was aimed to evaluate the chronic white matter (WM) changes and to detect the regions correlated with visuospatial memory in professional boxers.\nMaterials and Methods: Diffusion tensor images were performed for fifteen professional boxers (including 2 active boxers) and healthy controls (HC) on 3T MRI. Group difference was assessed using tract-based spatial statistics, and correlation between the WM changes and the Rey-Osterreich complex figure test (ROCFT) was assessed in professional boxers.\nResults: Professional boxers had lower fractional anisotropy (FA) value than HC in bilateral anterior thalamic radiation (ATR), corticospinal tract, cingulum, inferior fronto-occipital fasciculus (IFOF), superior and inferior longitudinal fasciculus (SLF/ILF), forceps major and minor, and corpus callosum (CC) (p<0.05). Especially, ROCFT (delayed recall) score showed negative correlation between FA value in the right ATR, IFOF, SLF, ILF and forceps major. (p<0.05)\nConclusions: In professional boxers, wide WM change in the cerebrum predominantly in th posterior tract is described, and the right posterior tract is related to visuospatial memory impairment.\n \ne\n日本語抄録600文字以内\n【目的】引退後のプロボクサーにおいて視空間記憶の障害が報告されているが、脳損傷の局在との関連は明らかではない。本検討ではプロボクサーの反復性軽度頭部外傷による慢性期白質障害を明らかにし、視空間記憶の障害に関係する脳領域を評価した。\n【方法】15名の男性プロボクサー(うち2名は現役選手)、および年齢を調整した13名の男性正常者に対して3T MRI装置で拡散テンソル画像を撮像した。Tract-Based Spatial Statisticsを用いてFractional Anisotropy (FA) 値の群間比較を行い、視覚性記憶の評価尺度としてRey-Osterriethの複雑図形 (ROCFT) を用いてボクサー群のFA値との相関解析を行った。\n【結果】プロボクサーは正常者と比較し、前視床放線、皮質脊髄路、帯状束、下前頭後頭束、上縦束、下縦束、小鉗子、大鉗子、脳梁の両側にFA値の低下を認めた (p < 0.05) 。さらにROCFの遅延再生課題において、前視床放線、下前頭後頭束、上縦束、下縦束、大鉗子のいずれも右側のみにFA値と負の相関を認めた (p < 0.05) が、左大脳白質に相関関係を認めた脳領域は無かった。\n【結論】プロボクサーの反復性軽度頭部外傷による慢性期白質障害は、脳梁の他に両側大脳半球で後方優位で広範に見られ、中でも右側の大脳白質障害は視空間記憶の障害に関連する。\n","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"第49回日本神経放射線学会","subitem_description_type":"Other"}]},"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":"宮田, 真里"}],"nameIdentifiers":[{"nameIdentifier":"954857","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高畑, 圭輔"}],"nameIdentifiers":[{"nameIdentifier":"954858","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"島田, 斉"}],"nameIdentifiers":[{"nameIdentifier":"954859","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"久保田, 学"}],"nameIdentifiers":[{"nameIdentifier":"954860","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐野, 康徳"}],"nameIdentifiers":[{"nameIdentifier":"954861","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本, 保天"}],"nameIdentifiers":[{"nameIdentifier":"954862","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三村, 將"}],"nameIdentifiers":[{"nameIdentifier":"954863","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"樋口, 真人"}],"nameIdentifiers":[{"nameIdentifier":"954864","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mari, Miyata","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954865","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keisuke, Takahata","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954866","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hitoshi, Shimada","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954867","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manabu, Kubota","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954868","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasunori, Sano","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamamoto, Yasuharu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masaru, Mimura","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makoto, Higuchi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"954872","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"プロボクサーにおける慢性期白質障害と視空間記憶障害の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"プロボクサーにおける慢性期白質障害と視空間記憶障害の関係"},{"subitem_title":"Assessment of chronic white matter changes and visuospatial memory impairment in professional boxers","subitem_title_language":"en"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-05-26"},"publish_date":"2021-05-26","publish_status":"0","recid":"82876","relation_version_is_last":true,"title":["プロボクサーにおける慢性期白質障害と視空間記憶障害の関係"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:07:20.468763+00:00"}
