The technique focuses mainly on acquisition of T(2)-weighted or contrast-enhanced T(1)-weighted images in adults; its utility for nonenhanced T(1)-weighted imaging in children is not well established. We compared the quality of T(1)-weighted fluid-attenuated inversion recovery brain imaging with BLADE (T(1)-FLAIR-BLADE) to that of conventional spin-echo T(1)-weighted imaging (T(1)-SE) in pediatric patients who cannot stay still during MR imaging.\n\\nMATERIALS AND METHODS: Our investigation included a volunteer study and a retrospective clinical study. Six healthy adult volunteers underwent scanning to compare the contrast of T(1)-SE, T(1)-weighted fluid-attenuated inversion recovery imaging (T(1)-FLAIR), and T(1)-FLAIR-BLADE at both 1.5 and 3 tesla. Comparison was based on scores assigned independently by 2 blinded observers and by calculated contrast-to-noise ratio. The clinical study included 20 children who underwent both T(1)-SE and T(1)-FLAIR-BLADE at either 1.5 (n = 9) or 3 T (n = 11). On each sequence, 2 blinded observers independently scored visualization of the cerebral gyri and contrast between gray and white matter. We compared scores between sequences separately for 1.5 and 3T using Wilcoxon signed-rank tests.\n\\nRESULTS: At both 1.5 and 3T, contrast was better using T(1)-FLAIR and T(1)-FLAIR-BLADE than T(1)-SE in volunteers, and overall scores were significantly higher with T(1)-FLAIR-BLADE (P < 0.05) than T(1)-SE in the clinical study.\n\\nCONCLUSION: T(1)-FLAIR-BLADE may be superior to T(1)-SE in demonstrating brain structures in children who cannot stay still and may be used to supplement or replace T(1)-SE when T(1)-SE is insufficient for patient motion.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-3182","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":"Tachibana, Yasuhiko"}],"nameIdentifiers":[{"nameIdentifier":"463011","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Niwa, Tetsu"}],"nameIdentifiers":[{"nameIdentifier":"463012","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kusagiri, Kouki"}],"nameIdentifiers":[{"nameIdentifier":"463013","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aida, Noriko"}],"nameIdentifiers":[{"nameIdentifier":"463014","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"463015","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"立花 泰彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"463016","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"丹羽 徹","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"463017","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"草切 孝貴","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"463018","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"相田 典子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"463019","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":"Effective Performance of T1-weighted FLAIR Imaging with BLADE in Pediatric Brains","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effective Performance of T1-weighted FLAIR Imaging with BLADE in Pediatric Brains"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-12-21"},"publish_date":"2012-12-21","publish_status":"0","recid":"46469","relation_version_is_last":true,"title":["Effective Performance of T1-weighted FLAIR Imaging with BLADE in Pediatric Brains"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:51:26.413922+00:00"}
