| Abstract | 「要旨」骨悪性腫瘍11例と軟部悪性腫瘍11例における67GaシンチグラムとMRI所見の特徴を分析した. 骨肉腫におて67Gaシンチグラムは高集積を示しMRIはT1強調画像で低信号レベルを示した. T2強調画像では高信号レベルを示す症例があったが明瞭な特徴は認めなかった. 軟骨肉腫は中程度の67Ga集積を示し, T1で比較的低信号レベル, T2で高信号レベルを示した. Ewing肉腫は67Ga集積は低く, またMRIは中信号レベルであった. 軟部悪性腫瘍は骨悪性腫瘍よりも67Ga集積は概して低い結果であった. 悪性線維性組織球腫は中程度の67GaとT1低信号レベル, T2で高信号レベルを示した. 脂肪肉腫は67Ga集積は低く, T1中信号レベル, T2で高信号レベルを示した. これらの特徴を理解するために得られた結果の三次元表示を試みた. |

| Abstract | [Summary]We have analyzed the characteristics of 67Ga scintigram and MRI in 11 malignant bone tumors and 11 malignant soft tissue tumors. Osteosarcoma showed a high accumulation in 67Ga scintigram and low signal intensity in T1 weighted image. T2 weighted image were not characteristic. Chondrosarcoma showed medium 67Ga accumulation and low signal in T1 weighted image and high signal in T2 weighted image. Ewing sarcoma showed low accumulation in 67Ga scan and medium intensity in MRI. Malignant soft tissue tumors showed rather low 67Ga accumulation compared with malignant bone tumors. Malignant fibrous histiocytoma showed medium accumulation of 67Ga, low signal in T1 weighted image and high signal in T2 weighted image. Liposarcoma showed low 67Ga accumulation and medium signal in T1 weighted image and high signal in T2 weighted image. To summarize these characteristics, three dimensional display is demonstrated. |
