| Abstract | 「要旨」われわれは, 骨疾患に対する201Tlの集積態度を検討した. 原発性骨腫瘍6例 (良性4例, 悪性2例), 転移性骨腫瘍11例, 炎症性骨疾患5例, その他3例の計25例について, X線所見, 99mTc-MDPを, 主に201Tlとの比較を試みた. 良性骨病変では, 201Tlの集積が陰性である傾向が強く認められた. 悪性骨病変では, 99mTc-MDPの集積のいかんを問わず, 201Tlの集積が陽性である傾向が認められ, 特に "cold lesion" に対しては, その有用性が示唆された. また, 炎症性骨疾患の急性, 慢性についても, 201Tl, 99mTc-MDPとの比較を行なってみた. 症例を供覧し, 若干の考察を加えた. |

| Abstract | [Summary] Recently 201Tl chloride is used for myocardial imaging, renal medullary imaging and tumor detection, but there is little published information on the 201Tl scanning in patients with bone disease. A comparative study of the efficacy of 201Tl and 99mTc-MDP bone scanning in detecting bone disease was performed 25 patients with bone disease, who had abnormal radiographic findings, were studied by bone scanning with 201Tl and were compared to 99mTc-MDP in 24 lesions (11 benign and 13 malignant lesions). The result on these patients showed that, (1) 201Tl and 99mTc-MDP bone images were in agreement with each other in 4 of 11 lesions with benign disease and 5 of 13 lesions with malignant disease, (2) positive images with 201Tl were obtained in 11 of 13 malignant lesions, whereas only 3 of 11 benign lesions showed positive images with 201Tl, on the other hand, positive ratio of 99mTc-MDP scanning was 10/11 for benign and 7/13 for malignant lesions, (3) all of 4 cold lesions with malignant disease on 99mTc-MDP images were positively delineated with 201Tl. From these observations, some promise is offered by the use of 201Tl in allowing differentiation between malignant and benign bone disease. It is also suggestive that bone images with 201Tl could delineate the cold lesion in 99mTc-MDP bone scanning. |
