| Abstract | 「緒言」慢性甲状腺炎は1912年橋本の報告以来, 多数の病理学的ならびに臨床的報告がなされている. 殊に臨床検査中, RIによる検査成績は甲状腺疾患全般を通じて重要な資料であり, その中でもシンチグラムの占める役割は大きいものがある. 慢性甲状腺炎の場合には両葉が瀰慢性に肥大し, 131Iの摂取が不均等で所謂「まだら像」を呈するものがかなり多いことが従来より指摘されている. この「まだら像」の頻度は報告者により差があるが, その存在については異論はないようである. 著者等はこの「まだら像」がいかなる機序によりシンチグラム上に記録されるかその成因について検討を行い, ついで, その成績が慢性甲状腺炎診断へ応用可能であるか否かについて検討を行った. 甲状腺シンチグラム作製にはシンチスキャナとガンマ・カメラが用いられているが, 一般にシンチスキャナによるものが多い. |

| Abstract | [Summary] The study was carried out in order to clarify the cause of appearance of mottled pattern in the scintigram of chronic thyroiditis, and in order to investigate its usefulness for clinical diagnosis. A total of 129 cases were. studied. 35 of the cases were chronic thyroiditis and the other 94 cases were classified as follows: hyperthyroidism, 40; Struma simplex, 40; normal, 14. The thyroid gland uptake (U) of 131I (% of dose) was measured in all cases and the thyroid gland weight (G) was calculated using the empirical formula of Allen-Goodwin and simultaneously the thyroid gland volume (V) was estimated using that of Himanka and Larsson. It was thought that the change of the picture of mottled pattern it the thyroid scintigram depends upon the different methods of administration of 131I, so two different methods of investigation were performed. [The results were as following]: 1) In the cases of chronic thyroiditis, both the value of U/G and that of U/V were lower than in the cases of hyperthyroidism, struma simplex and normal. It seemed, therefore, to be quite plausible that the picture of mottled pattern in the case of the same administration dosage of 131I appeared because of these low value. 2) In the cases of chronic thyroiditis, both the value of 1/G and that of 1/V were also lower than in the cases of struma simplex and normal. It was, however, slightly difficult to differ from the cases of hyperthyroidism. It seemed to be evident that the picture of mottled pattern in the case of the same accumulation dosage of 131I appeared because of these low value. From the above, both the value of U/G2 and that of U/V2 in every case were calculated. in the cases of chronic thyroiditis, these values were most lowest among all cases. It may be concluded that in the cases of chronic thyroiditis the method calculating the value of U/G2 or U/V2 is one of the appropriate methods to evaluate the thyroid function. |
