There were 160 study patients (80 premenopausal, 80 postmenopausal). Degree of BPE was classified into minimal, mild, moderate, or marked. Mammographic density was classified into fatty, scattered, heterogeneously dense, and extremely dense. BP echotexture on US and BP intensity on DWI were visually classified as homogeneous or heterogeneous. Apparent diffusion coefficient (ADC) values of normal breast tissue were measured. Associations of the degree of BPE with menopausal status, menstrual cycle, or imaging features were evaluated by univariate and multivariate analyses. No significant correlation was found between mammographic density and BPE (p=0.085), whereas menopausal status (p=0.000), BP echotexture (p=0.000), and BP intensity on DWI (p= 0.000), and ADC values (p=0.000) showed significant correlations with BPE. Multivariate analysis showed that postmenopausal status was an independent predictor of minimal BPE (p=0.002, OR=3.743). In premenopausal women, there was no significant correlation between menstrual cycle and BPE, whereas BP echotexture was an independent predictor of whether BPE was less than mild or greater than moderate (p=0.001, OR=26.575). BPE on breast MRI is associated with menopausal status and the findings of US and DWI. Because premenopausal women with heterogeneous BP echotexture may be predicted to show moderate or marked BPE, scheduling of breast MRI should preferentially be adjusted to the menstrual cycle.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "URI", "subitem_identifier_uri": "http://www.med.nagoya-u.ac.jp/medlib/nagoya_j_med_sci/773.html"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/22973"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/nagjms.77.3.425", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Nagoya University Graduate School of Medicine, School of Medicine"}]}, "item_9_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN\uff08print\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7622", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kawamura, Akiko"}], "nameIdentifiers": [{"nameIdentifier": "60290", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Satake, Hiroko"}], "nameIdentifiers": [{"nameIdentifier": "60291", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ishigaki, Satoko"}], "nameIdentifiers": [{"nameIdentifier": "60292", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ikeda, Mitsuru"}], "nameIdentifiers": [{"nameIdentifier": "60293", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kimura, Reiko"}], "nameIdentifiers": [{"nameIdentifier": "60294", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Shimamoto, Kazuhiro"}], "nameIdentifiers": [{"nameIdentifier": "60295", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Naganawa, Shinji"}], "nameIdentifiers": [{"nameIdentifier": "60296", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-21"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "22_Kawamura.pdf", "filesize": [{"value": "507.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 507500.0, "url": {"label": "22_Kawamura.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/20843/files/22_Kawamura.pdf"}, "version_id": "9676759c-57e9-4366-bc3f-867d6410ea4f"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "background parenchymal enhancement", "subitem_subject_scheme": "Other"}, {"subitem_subject": "menopausal status", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mammography", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ultrasonography(US)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "diffusion-weighted imaging(DWI)", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Prediction of background parenchymal enhancement on breast MRI using mammography, ultrasonography, and diffusion-weighted imaging", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Prediction of background parenchymal enhancement on breast MRI using mammography, ultrasonography, and diffusion-weighted imaging"}]}, "item_type_id": "9", "owner": "1", "path": ["499/508/509/1787"], "permalink_uri": "https://doi.org/10.18999/nagjms.77.3.425", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2015-09-04"}, "publish_date": "2015-09-04", "publish_status": "0", "recid": "20843", "relation": {}, "relation_version_is_last": true, "title": ["Prediction of background parenchymal enhancement on breast MRI using mammography, ultrasonography, and diffusion-weighted imaging"], "weko_shared_id": null}
