[Comparison of different methods of medical images in the assessment of local extension of osteogenic sarcomas].
The authors compared different methods of medical visualisation (standard radiography, arteriography, quantitative isotope bone scan, telethermography, CT scan, visualisation by nuclear magnetic resonance) in 52 osteogenic sarcomas. In the majority of cases the diagnosis was suggested by standard X-rays at the first visit. CT scan and visualisation by nuclear magnetic resonance are the two basic examinations both in terms of assessing the future single block excision as well as deciding the approach to be used for biopsy. Telethermography and quantitative isotope bone scan usefully complement clinical examination and standard X-rays in following the course during chemotherapy. Arteriography is indicated only in the presence of large tumors threatening the vessels directly.
