CFVR in RCA was measured with 3T PC-MRI in 13 patients and was compared with thje MPR in the RCA territory determined by PET.〈Results〉CFVR in RCA was successfully determined with PC-MRI in all subjects. The CFVR in patients with impaired MPR (〈2.0) was significantly lower than that with preserved MPR(〈2.0) (1.3±0.3 vs 2.2±1.2, p=0.03). Using a CFVR threshold of 1.5, the sensitivity and specificity for detecting impaired MPR was 80% (4/5) and 100% (8/8), respectively.〈Conclusion〉CFVR determined by PC-MRI can provide noninvasive detection of impaired myocardial perfusion reserve, without radiation exposure and contrast media.", "subitem_description_type": "Abstract"}]}, "item_8_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "2014年度~2016年度科学研究費補助金(基盤研究(C))研究成果報告書", "subitem_description_type": "Other"}]}, "item_8_description_64": {"attribute_name": "科研費番号", "attribute_value_mlt": [{"subitem_description": "26461822", "subitem_description_type": "Other"}]}, "item_8_publisher_30": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "三重大学"}]}, "item_8_text_31": {"attribute_name": "出版者(ヨミ)", "attribute_value_mlt": [{"subitem_text_value": "ミエダイガク"}]}, "item_8_text_65": {"attribute_name": "資源タイプ(三重大)", "attribute_value_mlt": [{"subitem_text_value": "Kaken / 科研費報告書"}]}, "item_8_version_type_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "市川, 泰崇", "creatorNameLang": "ja"}, {"creatorName": "ICHIKAWA, Yasutaka", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "石田, 正樹", "creatorNameLang": "ja"}, {"creatorName": "ISHIDA, Masaki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "北川, 覚也", "creatorNameLang": "ja"}, {"creatorName": "KITAGAWA, Kakuya", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "佐久間, 肇", "creatorNameLang": "ja"}, {"creatorName": "SAKUMA, Hajime", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-05-08"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2018RP0062.pdf", "filesize": [{"value": "299.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 299000.0, "url": {"label": "2018RP0062", "url": "https://mie-u.repo.nii.ac.jp/record/12443/files/2018RP0062.pdf"}, "version_id": "9c00d4e4-e86b-4b73-91af-796b3b015dc7"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "冠血流計測", "subitem_subject_scheme": "Other"}, {"subitem_subject": "MRI", "subitem_subject_scheme": "Other"}, {"subitem_subject": "位相コントラストシネMRI", "subitem_subject_scheme": "Other"}, {"subitem_subject": "PET", "subitem_subject_scheme": "Other"}, {"subitem_subject": "心筋血流予備能", "subitem_subject_scheme": "Other"}]}, "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": "research report", "resourceuri": "http://purl.org/coar/resource_type/c_18ws"}]}, "item_title": "3T MRIによる冠血流予備能評価:心筋血流PET・FFRによる検証", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "3T MRIによる冠血流予備能評価:心筋血流PET・FFRによる検証", "subitem_title_language": "ja"}, {"subitem_title": "Assessment of coronary flow velocity reserve using 3T phase-contrast cine MRI: comparison with myocardial perfusion reserve determined by positron emission tomography", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "15", "path": ["1692684729425"], "permalink_uri": "http://hdl.handle.net/10076/00018075", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2019-05-08"}, "publish_date": "2019-05-08", "publish_status": "0", "recid": "12443", "relation": {}, "relation_version_is_last": true, "title": ["3T MRIによる冠血流予備能評価:心筋血流PET・FFRによる検証"], "weko_shared_id": -1}
