I-123 IMP SPECT imaging was reported to be useful diagnostic imaging tool, however the diagnostic values in terms of assessment of fused image with CT/MRI and the semi-quantitative evaluation of the IMP-SPECT are still left to be discussed.\n\n[Materials and Methods] \nAmong patients who visited our institution for carbon-ion radiotherapy, ten patients who received I-123 IMP SPECT imaging were enrolled in this investigation. Fifteen min and 24 hours after intravenous injection of the radiotracer, SPECT imaging was performed using a gamma camera (E.CAM, Canon Medical, Tokyo, Japan). All acquired SPECT images were fused with CT or MRI images using a fusion viewer software (AZE-Hayabusa, AZE, Japan). ROIs of the tumor, contralateral normal choroidal tissue and normal soft tissue referring to CT or MRI image were analyzed, followed by semi-quantitative evaluation was assessed using non-parametric Wilcoxon rank sum test.\n\n[Results]\nAll tumors were visualized clearly in the 24h-SPECT image than those in 15min-SPECT image. The uptake index (UI) of the tumor: (tumor count) / (normal soft tissue count) and the contralateral normal choroidal tissue: (normal choroidal tissue count) / (normal soft tissue count) were 3.16+/-0.97 and 1.35+/-0.17, respectively (p < 0.001). The tumor-to-normal tissue ratios was 7.78+/-5.10.\n\n[Conclusion]\nI-123 IMP SPECT imaging performed 24h after injection of the radiotracer and fusion-image-analysis with CT or MRI were useful for detection of the choroidal melanoma. Also semi-quantitative evaluation using the fused images using tumor-UI and T/N ratio were considered to be valuable imaging techniques for diagnosis of the choroidal melanoma.","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78回日本医学放射線学会総会","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":"山崎, 香奈"}],"nameIdentifiers":[{"nameIdentifier":"871428","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西井, 龍一"}],"nameIdentifiers":[{"nameIdentifier":"871429","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"東, 達也"}],"nameIdentifiers":[{"nameIdentifier":"871430","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"牧島, 弘和"}],"nameIdentifiers":[{"nameIdentifier":"871431","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"粕谷, 吾朗"}],"nameIdentifiers":[{"nameIdentifier":"871432","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"辻, 比呂志"}],"nameIdentifiers":[{"nameIdentifier":"871433","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉永, 恵一郎"}],"nameIdentifiers":[{"nameIdentifier":"871434","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鎌田, 正"}],"nameIdentifiers":[{"nameIdentifier":"871435","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamazaki, Kana","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871436","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishii, Ryuichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871437","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Higashi, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871438","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makishima, Hirokazu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871439","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kasuya, Goro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871440","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuji, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871441","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinaga, Keiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871442","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kamada, Tadashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"871443","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":"Assessment of SPECT-CT fusion images and semi-quantitative evaluation of I-123 IMP SPECT in patients with ocular choroidal melanoma.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Assessment of SPECT-CT fusion images and semi-quantitative evaluation of I-123 IMP SPECT in patients with ocular choroidal melanoma."}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-23"},"publish_date":"2019-04-23","publish_status":"0","recid":"75679","relation_version_is_last":true,"title":["Assessment of SPECT-CT fusion images and semi-quantitative evaluation of I-123 IMP SPECT in patients with ocular choroidal melanoma."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:51:44.373952+00:00"}
