[Uptake behavior of bone metastases of hypernephroma in the 99m Tc-MDP bone scintigram. A comparison with x-ray findings].

Ninety-one radiologically confirmed osteolytic metastases in 30 patients with hypernephromas were studied with regard to their uptake of 99mTc-MDP and this was compared with the radiological findings. In 16% of the radiologically proven metastases, there was no correlation with their isotope uptake. Compared with other bone metastases whose isotope uptake has been studied and described in the literature, there appears to be a higher proportion of hypernephroma secondaries that do not show uptake of 99mTc-MDP.
