Forty-one patients suspected of having traumatic vertebral fractures who underwent DSCT with virtual non-calcium imaging were included in this study. For comparison, radiation exposure was measured in 11 patients receiving DSCT with a radiation exposure reduction system, and in 14 patients receiving conventional multi-detector-row CT scans. Radiation exposure, detectability of fractures and visual image quality were assessed and compared between the groups. Radiation exposure was less with the non-calcium image than with the other methods. The CT number (x-ray absorption coefficient of a pixel in a CT) for the affected vertebrae was significantly higher than for normal vertebrae. When the threshold of the CT number was determined as -25.6 HU, the sensitivity was 100% and specificity was 92.6%. In most cases, the quality of the virtual non-calcium image was inferior to the fat-suppressed T2-weighted magnetic resonance images. The virtual non-calcium image technique obtained using DSCT can be a useful part of the clinical diagnosis of vertebral fractures.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Showa University Society"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15369/sujms.28.261"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-6380 "}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SUYAMA, Jumpei"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KATAYAMA, Yoichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHASHI, Masumi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NOZIMA, Kazunari"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASHIGAYA, Kenji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TSUJI, Hiroaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWASAKI, Haruhiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HOSHIKAWA, Yoshikazu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOBAYASHI, Rei"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUNECHIKA, Jiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GOKAN, Takehiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NIKAIDO, Kouji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-26"}],"displaytype":"detail","filename":"S28_261.pdf","filesize":[{"value":"493.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S28_261.pdf","url":"https://showa.repo.nii.ac.jp/record/543/files/S28_261.pdf"},"version_id":"ff30953b-f601-40e8-9d84-40fcafd70953"}]},"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":"departmental bulletin paper"}]},"item_title":"Assessment of the Diagnostic Value and Image Quality of Dual-source Computed Tomography in Lumbar Vertebral Fractures: Comparison with Magnetic Resonance Imaging","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Assessment of the Diagnostic Value and Image Quality of Dual-source Computed Tomography in Lumbar Vertebral Fractures: Comparison with Magnetic Resonance Imaging"}]},"item_type_id":"10002","owner":"1","path":["67"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-11"},"publish_date":"2017-05-11","publish_status":"0","recid":"543","relation_version_is_last":true,"title":["Assessment of the Diagnostic Value and Image Quality of Dual-source Computed Tomography in Lumbar Vertebral Fractures: Comparison with Magnetic Resonance Imaging"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T12:43:40.382253+00:00"}
