| Abstract | 「要旨」SPECT像の体輪郭表示のために線源の軽量化, 調液時の被曝軽減, 装着の簡便化を目的として面線源に相当する簡便な線源容器を作成し, 甲状腺癌131I治療後の患者の131I-SPECTに応用した. プラナー像と比べ131I-SPECTのみの場合は有効例が少なかったが, 体輪郭表示を行った場合は86.7%で有効となった. 部位別の検討では頸部において有用であり, 特に頸部リンパ節転移と甲状腺床の鑑別や, 縦隔リンパ節転移と骨転移の鑑別が容易となった. しかし, 瀰漫性の集積を示す肺転移症例については, 体輪郭表示を行ってもプラナー像以上の情報は得られなかった. 「I. はじめに」131I治療後のシンチグラムは主にプラナー像で行われているが, 甲状腺床と頸部リンパ節転移の集積の鑑別や骨転移の正確な部位の把握に苦慮する場合がある. |

| Abstract | In order to make the body outline clearly in SPECT images, we devised a simple line source holder with the objectives to have a lightweight line source, to reduce the radiation exposure to the staff and to make the system readily available. This technique was applied to evaluate the localizing lesions in patients with radioiodine treatment of thyroid cancer. 131I-SPECT imaging with body outline was found to be effective in 86.7 percent (13/15) of the cases compared with planar imaging. Clinically, the results significantly helped in the discrimination between cervical lymph node metastasis and thyroid bed, and between mediastinal lymph node metastasis and bone metastasis. In the case of multiple lung metastasis demonstrating diffuse accumulation in the lung fields, 131I-SPECT imaging with body outline did not provide an increase in sensitivity compared with planar imaging. This method is easy to perform and it is considered to be useful for localization of abnormal accumulation, relative to the body outline. |
