The subjects were 25 HCC patients (n=45 tumors) who had undergone Lp-TACE and chemical-shift MRI of the abdominal region from April 1, 2000 to March 31, 2012. The regions of interest (ROIs) were set as large as possible to include the Lipiodol accumulation region on computed tomography (CT) images and the hyperintense signal region in double-echo fast low-angle shot (FLASH), automatic-subtracted images on MRI. We then used both modalities to measure the CT value and signal intensity for each specimen. The MRI signal intensity was calculated by subtracting the background signal intensity from the measured value. The mean CT value for the 45 tumors in the 25 patients of 710 Houns field units (HU; range, 139–3,062 HU) was positively correlated with the mean MRI signal intensity of 43.5 (0–212). Tumors with a diameter≥2cm exhibited a stronger correlation between CT values and MRI signal intensity in areas of Lipiodol accumulation than tumors smaller than 2cm. A weaker correlation was observed between the CT values and MRI signal intensity in areas of Lipiodol accumulation when the period from Lp-TACE to MRI was shorter than a week compared to one week or over. Our findings suggest that chemical-shift MRI can detect Lipiodol accumulation in HCCs and could therefore be useful in evaluating such types of accumulation.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Showa University Society"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15369/sujms.27.261"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-6380"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"MIYAGAMI, Osamu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GOKAN, Takehiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OHGIYA, Yoshimitsu"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-07-26"}],"displaytype":"detail","filename":"S27_261.pdf","filesize":[{"value":"585.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S27_261.pdf","url":"https://showa.repo.nii.ac.jp/record/564/files/S27_261.pdf"},"version_id":"aea94242-c512-4f37-836c-4921c6388888"}]},"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":"departmental bulletin paper"}]},"item_title":"Chemical-shift Magnetic Resonance Imaging Performed after Chemoembolization of Hepatocellular Carcinoma —Signal Evaluation of Oil-based Contrast Agent—","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Chemical-shift Magnetic Resonance Imaging Performed after Chemoembolization of Hepatocellular Carcinoma —Signal Evaluation of Oil-based Contrast Agent—"}]},"item_type_id":"10002","owner":"1","path":["73"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-09-26"},"publish_date":"2016-09-26","publish_status":"0","recid":"564","relation_version_is_last":true,"title":["Chemical-shift Magnetic Resonance Imaging Performed after Chemoembolization of Hepatocellular Carcinoma —Signal Evaluation of Oil-based Contrast Agent—"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T12:42:42.894157+00:00"}
