Radioisotope scanning in bone tumours

ABSTRACT

Thirty-three patients having bone tumours [18 malignant 9 benign and 6 secondaries] are studied by technetium 99 m-phosphonate scanning. There was a higher percentage of diffusely increased activity [38.3%] in malignant tumours compared to that in benign tumours [22.2%]. The study showed that technetium 99 m bone scanning is of little value in the differentiation between malignant and benign bone tumours and in defining precisely the local extent of the tumour. On the other hand it showed a high sensitivity for early detection of bone secondaries
