We used data from 29 patients who were imaged at Showa University Hospital using the pulmonary embolism （PE）/DVT protocol and evaluated based on the diagnostic utility of VMI with dual-energy analysis. By VMI, we compared the computed tomography （CT） values of the femoral veins on both sides and the surrounding muscle tissues at 40keV and conventional imaging; two radiologists performed the visual evaluation in three stages. We also evaluated the CT values of thrombi for cases with DVT. We conducted a retrospective cohort study on 29 patients （18 males and 11 females） with a mean age of 66.8 （range: 31?86） years. DVT was confirmed in four of the subjects （13.7％）. Visual evaluation confirmed a significant difference between the CT values at 40keV and with conventional imaging （2.76 vs. 1.81;?P＜0.05）. CT values in the femoral vein were 274.67 （range: 186.35?63.31） Hounsfield units （HU） at 40keV and 109.46 （range: 74.54?155.66） HU with conventional imaging （P＜0.05）. Contrast-to-noise ratios （CNRs） ［（femoral vein CT value?adductor muscle CT value）/adductor muscle standard deviation （SD）］ were 11.77 （range: 3.93?26.33） HU at 40keV and 9.87 （range: 1.28?27.56） HU with conventional imaging （P＜0.05）. The thrombus/femoral vein ratio （CT value） was 0.34 at 40keV and 0.59 with conventional imaging, while the CNR was 17.52 at 40keV and 4.32 with conventional imaging; both differences were significant. Low-voltage contrast CT is beneficial for enhancing images of veins and it may also be very useful for detecting DVT.","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.30.107"}}]},"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":"YAMANA, Keita"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OHGIYA, Yoshimitsu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TASHIRO, Yuki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KURODA, Hanako"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TOYOFUKA, Kosuke"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GOKAN, Takehiko"}],"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":"S30_107.pdf","filesize":[{"value":"239.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S30_107.pdf","url":"https://showa.repo.nii.ac.jp/record/487/files/S30_107.pdf"},"version_id":"296c96cd-2b58-4083-b96a-b57684724778"}]},"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":"Evaluation of Deep Venous Thrombosis Using Dual-energy CT","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Evaluation of Deep Venous Thrombosis Using Dual-energy CT"}]},"item_type_id":"10002","owner":"1","path":["57"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-08-23"},"publish_date":"2018-08-23","publish_status":"0","recid":"487","relation_version_is_last":true,"title":["Evaluation of Deep Venous Thrombosis Using Dual-energy CT"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T12:45:36.925891+00:00"}
