| Abstract | 「要旨」胸骨はX線写真に写しにくい骨の一つであるが, 骨シンチグラムにおいても, 形, 大きさの個人差, 集積程度の強弱, 集積の局在性または欠損, 周囲の骨との関係等が読影をむずかしくしている. 骨シンチグラム読影精度の向上を目的として, 骨転移のない悪性腫瘍例 (330例) の骨シンチグラムを検討した. 胸骨の形, 大きさには個人差が多く, 胸骨の形の不鮮明な症例の頻度は9.1%にみられた. 胸骨角に限局した円形の集積 (sternal hot spot) は23%にみられ, 胸骨角のくびれた形にその頻度は高く, 鎖骨端, 第一肋骨端集積パターンとの関係は薄かった. 胸骨周囲の骨の非対称性集積は, 乳癌群で29%, 乳癌および肺癌を除いた群で5.5%にみられた. 肋軟骨集積は7.9%にみられた. |

| Abstract | [Summary] : It is difficult to visualize the sternum clearly on the routine radiographic examination, due mainly to its position. We have examined the sternum by the bone scintigram using 99mTc phosphorous complexes, in the cancer patients without skeletal metastasis. The purpose of this paper was undertaken to discriminate between the normal and pathological findings of the sternum on the images. In thirty cases out of 330, contour of the sternum was not clear. The sharpness and forms of the sternum were observed in many variety individually. The laterality of the radioactive accumulation in the normal sternal edge, the clavicles and the first ribs was often disclosed in the postoperative state of breast and lung cancer. By means of long period observation, a focal concentration of radionuclide at the sternal angle, we called "sternal hot spot" , did not always mean the metastasis of malignancy. The "sternal hot spot" was more commonly observed in the cases having the images of constricted sternal angle than the other cases, and the statistical significance was proved at the 95 percent level by x-test. But there was no statistical significant difference between the frequency of the "sternal hot spot" and the radionuclide accumulation in the sternal edge of the clavicle and the first ribs. In twenty-six cases out of 330, accumulation of the lower costal cartilage was identified more clearly than the ribs. |
