| Abstract | 「要旨」頭頸部腫瘍の19例について, 99mTc-MIBI SPECTを施行し, 主腫瘍とリンパ節転移への99mTc-MIBIの集積を視覚的に検討し, さらに主腫瘍についてはMIBI-indexを求め半定量的に検討した. 治療前後に施行した7例では, 治療効果との関係についても検討した. early scanでは95%の症例で主腫瘍への99mTc-MIBIの集積が確認できたが, delayed scanでは57%の症例でのみ集積が認められ, delayed scanの有用性は得られなかった. リンパ節転移への集積は24%の部位のみに確認された. 腫瘍径との比較では, 腫瘍が大きいほどMIBI-indexは高かった. 治療前後に行った例では, 統計学的有意差は得られなかったものの, 治療効果を反映してのMIBI-indexの低下傾向は得られたが, MRIで評価される腫瘍径に関わらずMIBI-indexの低下した例は得られなかった. |

| Abstract | [Summary]SPECT using 99mTc-MIBI was performed in patients with tumors in the head and neck in order to determine 99mTc-MIBI uptake in tumors and to evaluate the efficacy of 99mTc-MIBI imaging in the assessment of treatment response. A MIBI uptake index was calculated as the ratio of average counts/pixel in the tumor to average counts/pixel in the homologous contralateral side. Eighteen of 19(95%)of the cases had increased MIBI uptake in the tumor on early images, and 8 of 14(57%)of the cases had increased uptake of the tumor on delayed images. MIBI uptake was related to the size of the tumor. Only 6 of 25 of cervical lymph node metastases were detected by 99mTc-MIBI SPECT. In the tumors evaluated before and after radiotherapy, the superiority of 99mTc-MIBI SPECT over MRI was not obtained, but there was a tendency for MIBI-index to decrease after radiotherapy. |
