| Abstract | 「はじめに」近年99mTc-リン酸化合物が骨疾患の診断, とくに原発性骨腫瘍, 悪性腫瘍骨転移, 良性骨疾患などの診断において有用であることが確認された. 著者らの教室においても, その使用頻度は増加の傾向にあり, 悪性腫瘍の骨転移早期発見のスクリーニング検査法となりつつある. このように, 核医学診断の応用範囲の拡犬と検査対象者の増加にともなって, 臨床的には, 患者の被曝線量の軽減とともに, より良いイメージを得ること, 多くの被検者を処理することなどが問題となる. 一方, 67Gaなどの腫瘍シンチグラフィおよび全身骨シンチグラフィの場合は, 他の臓器のシンチグラフィに比し, 全身を含むという特殊性があり, 1被検者に対する検査時間も長くなる. とくに, 99mTc-リン酸化合物を使用しての悪性腫瘍の骨転移巣の発見のためには, 全身シンチグラフィは不可欠であると思われる. |

| Abstract | [Summary] We have designed a 4000 hole Di/Con diverging collimator, and skeletal scintigraphy with this proved to be valuable procedure. Ten adult patients were givened 2mCi/10kg of 99mTc-diphosphonate intravenously. Images were obtained 3hr post injection using a Toshiba GCA-102 scintillation camera. Using the 4000 hole Di/Con diverging collimator images of the pelvis, lumbar spine, thorax, and skull were taken. Both anterior and posterior views were performed. Next using a 1,200 hole diverging collimator a posterior view of the thorax was obtained. In addition, the suspected lesion was imaged with a 4000 hole parallel collimator. In this study, the mean study time was reduced from 60 min using the 1200 hole diverging collimator to 30 min using the 4000 hole Di/Con diverging collimator, and the images with both diverging collimators were similar. However, the distortion was remarkably with the 4000 hole Di/Con diverging collimator. Spinous and transverse processes of individual vertebrae were clearly seen with the 4000 hole parallel collimator, but not with both diverging collimators. We conclude that the 4000 hole Di/Con diverging collimator is useful for bone survey. If a more detailed view of suspicious area is required, a high resolution collimator should be necessary. |
