In nine patients with recent lacunar stroke, CT and MRI enhancement studies were performed on the same day. In MRI, injection of Gd-DTPA enhanced recent lesions in all patients except for one who was examined 4 weeks after ictus, and the effect was excellent. Recent infarcts could be identified only by Gd-MRI in four of nine patients. In patients with multiple small infarctions, the use of Gd-MRI makes it possible to distinguish recent infarcts from other lesions definitively. In order to clarify the significance of periventricular high intensity lesion (PVH) in T2-weighted (T2w) MRI, hemodynamic and neuropsychological examinations were carried out in 41 patients with multiple cerebral infarctions. All the patients had PVH, which was classified into three grades as follows; grade 1 (n=16) showing only a thin high intensity band along the body of lateral ventricles; grade 2 (n=15) showing a definite high intensity area around the lateral ventricles; grade 3 (n=10) demonstrating diffuse thick and irregular foci around the whole ventricles. In these patients, rCBF was measured by ^\u003c133\u003eXe inhalation methods. Initial Slope Index (ISI) was calculated for estimating rCBF. Mini-mental State Test (MMT) was also performed for evaluating the grade of psychological abnormality. ISI in patients with grade 3 was significantly higher than ISI in those with grade 1 (p\u003c0.05). The MMT score in patients with grade 1 was significantly higher than MMT in those with grade 2 and 3 (p\u003c0.05). Progression of PVH may be related with the reduction of the cerebral circulation and mental fuction in cases with multiple cerebral infarction. Ischemic and hemorrhagic lesions can be distinguished by MRI, because old intracerebral hemorrhages appear as hypointensity areas with or without hyperintensity areas on T2w images. In 92 patients with multiple infarctions, MRI was used to evaluate the incidence and distribution of coexisting old intracerebral hemorrhages. Old hemorrhages were found in 15 patients (16.3%). All the old hemorrhages were located where hypertensive hemorrhages commonly occur. High-field MRI is useful for assessing the coexistence of hemorrhages in hypertensive patients with mutiple cerebral infarctions.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "130286", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Miyashita, Kotaro"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟医学会"}]}, "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": "AN00182415", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00290440", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "宮下, 光太郎"}], "nameIdentifiers": [{"nameIdentifier": "130285", "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": "2019-08-16"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "105(9)_601-613.pdf", "filesize": [{"value": "8.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 8800000.0, "url": {"label": "105(9)_601-613.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/21278/files/105(9)_601-613.pdf"}, "version_id": "35d4bdd4-4b6c-41fe-8194-24ef6e3d5788"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "MRI", "subitem_subject_scheme": "Other"}, {"subitem_subject": "multiple cerebral infarction", "subitem_subject_scheme": "Other"}, {"subitem_subject": "clinical usefulness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "核磁気共鳴画像", "subitem_subject_scheme": "Other"}, {"subitem_subject": "多発性脳梗塞", "subitem_subject_scheme": "Other"}, {"subitem_subject": "臨床的有用性", "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": "多発性脳梗塞症例におけるMRIの有用性に関する研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "多発性脳梗塞症例におけるMRIの有用性に関する研究"}, {"subitem_title": "多発性脳梗塞症例におけるMRIの有用性に関する研究", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1182"], "permalink_uri": "http://hdl.handle.net/10191/39391", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-10"}, "publish_date": "2016-03-10", "publish_status": "0", "recid": "21278", "relation": {}, "relation_version_is_last": true, "title": ["多発性脳梗塞症例におけるMRIの有用性に関する研究"], "weko_shared_id": null}
