Five different sequences with different parameters including respiration-triggered acquisition or multiple breath-holding, slice thicknesses of 3 or 5 mm, and different numbers of signal averaging and b values were compared. FA and apparent diffusion coefficients (ADCs) of the cortex and medulla were measured. Measurement error within the same and repeated examination was examined using within-individual standard deviation (Sw).\n RESULTS: FAs of the renal cortex were lower than the medulla (mean value of a sequence ranging 0.148-0.224, 0.433-0.476) and the ADCs of the cortex were higher than the medulla (2.26-2.69x10(-3) mm2/s, 1.77-2.19x10(-3) mm2/s) in all sequences (P<0.001). The renal cortex-medulla difference was the largest, with respiratory trigger- ing including a 3-mm slice thickness, three signal averages,and a b-value=0, 200, or 400 s/mm2 (P<0.001). Sw tended to be smaller in the sequence with a b-value of 400 s/mm2. \nCONCLUSION: DTI of kidneys with respiratory triggering is feasible with excellent cortex-medulla differentiation.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1002/jmri.21669","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1053-1807","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":"Kataoka, Masako"}],"nameIdentifiers":[{"nameIdentifier":"452704","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kido, Aki"}],"nameIdentifiers":[{"nameIdentifier":"452705","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamoto, Yuji"}],"nameIdentifiers":[{"nameIdentifier":"452706","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koyama, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"452707","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Isoda, Hiroyoshi"}],"nameIdentifiers":[{"nameIdentifier":"452708","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maetani, Youji"}],"nameIdentifiers":[{"nameIdentifier":"452709","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Umeoka, Shigeaki"}],"nameIdentifiers":[{"nameIdentifier":"452710","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tamai, Ken"}],"nameIdentifiers":[{"nameIdentifier":"452711","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Saga, Tsuneo"}],"nameIdentifiers":[{"nameIdentifier":"452712","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Morisawa, Nobuko"}],"nameIdentifiers":[{"nameIdentifier":"452713","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Togashi, Kaori"}],"nameIdentifiers":[{"nameIdentifier":"452714","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"452715","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐賀 恒夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"452716","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":"Diffusion Tensor Imaging of Kidneys With Respiratory Triggering: Optimization of Parameters to Demonstrate Anisotropic Structures on Fraction Anisotropy Maps","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Diffusion Tensor Imaging of Kidneys With Respiratory Triggering: Optimization of Parameters to Demonstrate Anisotropic Structures on Fraction Anisotropy Maps"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-06-29"},"publish_date":"2009-06-29","publish_status":"0","recid":"45559","relation_version_is_last":true,"title":["Diffusion Tensor Imaging of Kidneys With Respiratory Triggering: Optimization of Parameters to Demonstrate Anisotropic Structures on Fraction Anisotropy Maps"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:02:17.286310+00:00"}
