Description
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 images 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.
