We evaluated the influence of higher magnetic field strength and higher spatial resolution for identifying the trochlear nerve with three-dimensional constructive interference of steady state (3D CISS) sequence. Two radiological technologists, who were specifically trained for the observation of the trochlear nerve on MRI, challenged to generate multiple images by a multiplanar reconstruction (MPR) technique with adaptively varying the MPR parameters (e.g. oblique direction and slice location) according to the cisternal course of the trochlear nerve from the point of exit to the tentorial edge. The trochlear nerve identification was significantly better on 3T MR images than on 1.5T MR images. The mean distance of the nerve measured on thin-slice (0.25 mm) 3T MR images was significantly longer than those on 3T MR images (0.5-mm slice thickness), followed by those on 1.5T MR images (0.5-mm slice thickness). High-resolution 3T MR imaging accompanied with the proper image reconstruction by the MPR technique enables reliable identification of the trochlear nerve.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "164150", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kanazawa, Tsutom"}]}, {"nameIdentifiers": [{"nameIdentifier": "164151", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ohkubo, Masaki"}]}, {"nameIdentifiers": [{"nameIdentifier": "164152", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kondo, Tatsuya"}]}, {"nameIdentifiers": [{"nameIdentifier": "164153", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Iwasaki, Tomoya"}]}, {"nameIdentifiers": [{"nameIdentifier": "164154", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Takahashi, Naoya"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学医学部保健学科"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12680484", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "21884617", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "金沢, 勉"}], "nameIdentifiers": [{"nameIdentifier": "164145", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "大久保, 真樹"}], "nameIdentifiers": [{"nameIdentifier": "164146", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "近藤, 達也"}], "nameIdentifiers": [{"nameIdentifier": "164147", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "岩崎, 友也"}], "nameIdentifiers": [{"nameIdentifier": "164148", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "高橋, 直也"}], "nameIdentifiers": [{"nameIdentifier": "164149", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "15(1)_49-56.pdf", "filesize": [{"value": "1.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1900000.0, "url": {"label": "15(1)_49-56.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28526/files/15(1)_49-56.pdf"}, "version_id": "75f7a364-6dcc-4075-aae0-45b11d9a6e6d"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Magnetic Resonance Imaging", "subitem_subject_scheme": "Other"}, {"subitem_subject": "3D-constructive interference in steady state", "subitem_subject_scheme": "Other"}, {"subitem_subject": "滑車神経", "subitem_subject_scheme": "Other"}, {"subitem_subject": "スライス厚", "subitem_subject_scheme": "Other"}, {"subitem_subject": "部分体積効果", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Trochlear Nerve", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Slice Thickness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Partial Volume Effect", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "3T-MRIにおける3D-CISS法を用いた滑車神経描出の検討", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "3T-MRIにおける3D-CISS法を用いた滑車神経描出の検討"}, {"subitem_title": "3T-MRIにおける3D-CISS法を用いた滑車神経描出の検討", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1626"], "permalink_uri": "http://hdl.handle.net/10191/49821", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-04-05"}, "publish_date": "2018-04-05", "publish_status": "0", "recid": "28526", "relation": {}, "relation_version_is_last": true, "title": ["3T-MRIにおける3D-CISS法を用いた滑車神経描出の検討"], "weko_shared_id": null}
