The stiffness of the cylindrical phantom was measured at 0, 13 and 18 months. Storage and loss moduli were measured with MRE, and shear-wave speed (SWS) was measured with US SWE. Long-term stability was evaluated in accordance with the Quantitative Imaging Biomarker Alliance (QIBA) profiles for each modality. The initial storage and loss moduli of the phantom were 5.01±0.22 and 1.11±0.15 respectively, and SWS was 2.57±0.04 m/s. The weight of the phantom decreased by 0.6% over the 18 months. When measured with MRE, the stiffness of the phantom decreased and changes to the storage and loss moduli were -3.0% and -4.6% between 0 and 13 months, and -4.3% and 0.0% between 0 and 18 months. The US measurements found that SWS decreased by 2.4% over the first 13 months and 3.6% at 18 months. These changes were smaller than the tolerances specified in the QIBA profiles, so the viscoelastic PAAm gel phantom fulfilled the condition for long-term stability. This new phantom has the potential to be used as a quality assurance and quality control phantom for MRE and US SWE.","subitem_description_type":"Abstract"}]},"item_8_relation_13":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"34019551","subitem_relation_type_select":"PMID"}}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1371/journal.pone.0250667","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0250667","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1932-6203","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":"Usumura, Masashi"}],"nameIdentifiers":[{"nameIdentifier":"1015824","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishimoto, Riwa"}],"nameIdentifiers":[{"nameIdentifier":"1015825","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ishii, Koki"}],"nameIdentifiers":[{"nameIdentifier":"1015826","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hotta, Eika"}],"nameIdentifiers":[{"nameIdentifier":"1015827","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kershaw, Jeff"}],"nameIdentifiers":[{"nameIdentifier":"1015828","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Higashi, Tatsuya"}],"nameIdentifiers":[{"nameIdentifier":"1015829","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Obata, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"1015830","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suga, Mikio"}],"nameIdentifiers":[{"nameIdentifier":"1015831","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masashi, Usumura","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015832","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Riwa, Kishimoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015833","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kershaw, Jeffrey","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015834","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tatsuya, Higashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015835","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takayuki, Obata","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1015836","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":"Longitudinal stability of a multimodal visco-elastic polyacrylamide gel phantom for magnetic resonance and ultrasound shear-wave elastography.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Longitudinal stability of a multimodal visco-elastic polyacrylamide gel phantom for magnetic resonance and ultrasound shear-wave elastography."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-06-02"},"publish_date":"2021-06-02","publish_status":"0","recid":"82908","relation_version_is_last":true,"title":["Longitudinal stability of a multimodal visco-elastic polyacrylamide gel phantom for magnetic resonance and ultrasound shear-wave elastography."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:42:09.330432+00:00"}
