We discuss the use of 31P-MRS to assess the long-term prognosis from the time when MRS was performed. METHODS: We studied 20 patients with renal allografts. 1.5 Tesla clinical magnetic resonance imaging (MRI) and 15 cm surface coil was used for 31P-MRS. Localized 31P-MRS was done using image selected in vivo spectroscopy (ISIS) method. Individual peaks were fitted by Lorenzian line-shapes with a least square method and peak area ratios were calculated. RESULTS: A beta-adenosine triphosphate/inorganic phosphate (beta-ATP/Pi) ratio >1.2 had sensitivity of 92.8%, specificity of 100%, and accuracy of 95% for predicting 3-year renal survival; a beta-ATP/Pi ratio >1.2 had sensitivity of 90.9%, specificity of 66.7%, and accuracy of 76.9% for predicting 5-year renal survival. We compared 31P-MRS spectra data between the survived group and failed group. The survived group had significantly higher beta-ATP/Pi, alpha-ATP/Pi, and phosphodiester (PDE)/Pi ratios than the failed group. CONCLUSIONS: We discussed the beta-ATP/Pi value as a parameter for predicting long-term survival of a transplanted kidney from the time when MRS was performed. A value above 1.2 suggests a high probability of 3-year renal survival, whereas a value over 2.5 indicates that the transplanted kidney could survive over 5 years. 31P-MRS may be useful for predicting long-term survival of transplanted kidneys, but additional studies are needed.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0041-1337","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":"Ikehira, Hiroo"}],"nameIdentifiers":[{"nameIdentifier":"437428","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Obata, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"437429","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanada, Shuji"}],"nameIdentifiers":[{"nameIdentifier":"437430","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"437431","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池平 博夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437432","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小畠 隆行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437433","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"棚田 修二","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"437434","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":"Long-term assessment of posttransplant renal prognosis with 31P magnetic resonance spectroscopy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Long-term assessment of posttransplant renal prognosis with 31P magnetic resonance spectroscopy"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-03-15"},"publish_date":"2006-03-15","publish_status":"0","recid":"44014","relation_version_is_last":true,"title":["Long-term assessment of posttransplant renal prognosis with 31P magnetic resonance spectroscopy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:20:25.755548+00:00"}
