| Abstract | 「要旨」130例の悪性腫瘍を含む168例の頭頸部疾患患者に67Ga全身シンチグラフィとSPECTを併せて施行し80%に陽性結果を得た. これは悪性リンパ腫を除外しても同じであり, 従来の報告よりも高い値である. SPECTを併用することによってplanar imageのみでは描出不可能か確認できなかったものが陽性となりpositive rateが上昇したと考えられた. 陽性所見の得られた症例の約半数でSPECTは異常集積の存在や範囲に関して付加する情報をもたらし, 特に上咽頭, 中咽頭, 上顎癌の診断に有用であった. 67Gaシンチグラフィはまた頭頸部領域を越えた病巣も描出し, 転移や不明の原発巣の検索に有用であった. さらに再発の診断にも他の検査法では得られないか, あるいは組み合わせによって有力な診断的情報をもたらした. SPECTを併用することにより頭頸部領域の悪性腫瘍の診断にもGaシンチグラフィは有用であると考えられる. |

| Abstract | [Summary]Spatial distribution of a radionuclide is well visualized by single photon emission computed tomography (SPECT) and 67Ga imaging in terms of malignant tumor diagnosis is expected to be improved. One hundred and sixty-eight patients with various head and neck diseases including 130 malignant tumor cases were examined by whole body scintigraphy in combination with SPECT using 67Ga citrate, and positive results were obtained in 80% of the malignant lesions. SPECT presented additional informations regarding distribution of the radionuclide in half as much as the positive cases. Main advantage of SPECT was considered that separated image of the lesion from the background was available in transaxial plane and in some cases, only SPECT identified presence of tumors. Combined use of whole body scintigraphy with SPECT using 67Ga citrate is useful for detection of head and neck tumors and their distant metastases. |
