Abstract | 「はじめに」肝シンチグラムは肝臓の形態, 機能及び病変の局在性の検査を目的とする診断法であるが, Stirrett (1953) がRISAを用いてその臨床的意義を明らかにして以来種々の研究, 開発が進められ, 今日では肝疾患とくに限局性病変の検出には欠くべからざる診断法となりつつある. しかしながら, この肝シンチグラムが臨床診断と治療の適応の指針となるためには種々の条件が必要でありまたその目的に対応する工夫を要望されるものであり単純に無条件に臨床的な応用に供しうるものではない. とくに肝癌その他の悪性病変を対象とする早期発見, 早期手術の軌道的役割を果すためには, 所謂Space Occupying Lesionをどの程度まで検出しうるか, またいかなる核種を選択すべきであるかなどの点は依然として肝シンチグラム法の課題であろう. |

Abstract | [Summary] The autors evaluate clinical significance about the liverscintigram employing 99mTc-sulfur colloid on comparison with 198Au colloid, and the conclusion is summarizedas followings ; 1. 99mTc-sulfur colloid is so available to delineate even the tumor-model of 1.0 cm. in diameter on the surface of phantom, but is impossible to detect the tumor-model of less 5.0 cm. in diameter on the depth of 5.0 cm., which is delineated by 198Au colloid. 2. The liver scintigraphy using the radiopharmaceuticals is performed in fifty cases withnormal and liver disease. i) A given dose of 99mTc sulfur colloid is decide depending upon count rate of the liver, and 15-20μCi per a kilogram is injected intravenously. (on using 3x2" crystal) ii) 99mTc-sultur colloid is available to demonstrate high contrast on the scintigram, and delineate clearly lower margin and left lobe of the liver on comparison with 198Au colloid. iii) 99mTc-sulfur collid is also available to establish a diagnosis of metastatic tumor of the liver because of clear delineation with the superficial lesion. iv) 99mTc-sulfur colloid is possible to be used for the spleen scintigraphy because an image of the spleen is frequently taken, and a pathophysiological condition of the liver is supposed by the difference of density on the scintigram. v) The side effect of 99mTc-sulfur colloid is negligible. |
