Because the chemical structure of haloperidol contains fluorine, in vivo 19F-magnetic resonance (MR) spectroscopy (repetition time (TR) = 1 s) and chemical shift imaging (CSI; TR = 1 s, pixel size = 15 x 15 mm) were performed in schizophrenic patients who were treated with haloperidol decanoate (three men and one woman) to measure its diachronic change at the injection point and visualize its local distribution after intramuscular injection. 19F signals (T1 time = 365 ms) were obtained at the haloperidol decanoate-injected region. The decrease rate of the signal-to-noise ratio (SNR) by 19F-MR spectroscopy seemed large in comparison with that of the plasma haloperidol concentration. The distribution was clearly visualized by 19F-CSI for a few days after the injection, but after 1 week could no longer be seen. Although the slow-release characteristics of depot neuroleptics have been explained by the slow diffusion of esterified neuroleptics from the oil vehicle, this result may suggest that there are other mechanisms involved in maintaining the plasma haloperidol concentration. In vivo 19F-MR spectroscopy and CSI are potentially applicable for the pharmacokinetic analysis of haloperidol and other drugs containing fluorine in their structure.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1323-1316","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":"Sassa, Takeshi"}],"nameIdentifiers":[{"nameIdentifier":"437478","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suhara, Tetsuya"}],"nameIdentifiers":[{"nameIdentifier":"437479","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikehira, Hiroo"}],"nameIdentifiers":[{"nameIdentifier":"437480","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Obata, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"437481","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Girard, F"}],"nameIdentifiers":[{"nameIdentifier":"437482","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanada, Shuji"}],"nameIdentifiers":[{"nameIdentifier":"437483","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okubo, Yoshiro"}],"nameIdentifiers":[{"nameIdentifier":"437484","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐々 毅","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437485","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"須原 哲也","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437486","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池平 博夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437487","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小畠 隆行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437488","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"棚田 修二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437489","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大久保 善朗","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437490","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":"19F-magnetic resonance spectroscopy and chemical shift imaging for schizophrenic patients using haloperidol decanoate","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"19F-magnetic resonance spectroscopy and chemical shift imaging for schizophrenic patients using haloperidol decanoate"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-03-16"},"publish_date":"2006-03-16","publish_status":"0","recid":"44019","relation_version_is_last":true,"title":["19F-magnetic resonance spectroscopy and chemical shift imaging for schizophrenic patients using haloperidol decanoate"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:20:22.126399+00:00"}
