MATERIAL and METHOD: Eighteen patients having malignant melanoma in head and neck regions undertook carbon-ion radiotherapy at the National Institute of Radiological Sciences, Chiba, Japan. We examined using DWIBS (diffusion-weighted imaging with background body signal suppression) method before and after the treatment. ADC (apparent diffusion coefficient) value was measurable in nine of 18 cases (mean age:65yrs,age range:56-78,5 males and 4 females). We compared the ADC value before the treatment with the after one. Intera Achieva 1.5T Nova Dual system (Philips Medical) was used for the examination. The EPI-based diffusion-weighted imaging sequence with SPIR fat suppression was applied at the settings of two b-values, namely 0 and 1000 sec/mm^2, respectively. \nResults: Average ADC value for all clinical cases were 0.897x10^-3 (S.D.: 0.142x10^-3) at pre-treatment and 1.355x10^-3 (S.D.: 0.573x10^-3) at post-treatment. ADC values were increased in eight of 9 cases and decreased in one. There was a significant difference in ADC value between pre- and post-treatment (P<0.028).\nCONCLUSIONS: DWIBS examination for malignant melanoma in head and neck showed significant increases in ADC value after carbon-ion radiotherapy. The ADC value has the possibility of becoming a criteria when you judge the effect of the carbon-ion radiotherapy in malignant melanoma.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"ECR2007 19th European Congress of Radiology","subitem_description_type":"Other"}]},"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":"Tanabe, Kouji"}],"nameIdentifiers":[{"nameIdentifier":"675924","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kandatsu, Susumu"}],"nameIdentifiers":[{"nameIdentifier":"675925","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishimoto, Riwa"}],"nameIdentifiers":[{"nameIdentifier":"675926","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizoe, Junetsu"}],"nameIdentifiers":[{"nameIdentifier":"675927","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田辺 耕士","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"675928","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"神立 進","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"675929","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岸本 理和","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"675930","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"溝江 純悦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"675931","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"MR Diffusion-weighted imaging(DWI) of Malignant Melanoma in Head and Neck after Accelerated Carbon-Ion Radiotherapy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MR Diffusion-weighted imaging(DWI) of Malignant Melanoma in Head and Neck after Accelerated Carbon-Ion Radiotherapy"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-03-19"},"publish_date":"2007-03-19","publish_status":"0","recid":"68872","relation_version_is_last":true,"title":["MR Diffusion-weighted imaging(DWI) of Malignant Melanoma in Head and Neck after Accelerated Carbon-Ion Radiotherapy"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:21:07.641694+00:00"}
