[A comparison of radiology and scanning with 99mTc-pyrophosphate in 125 patients with tumours (author's transl)].

Various portions of the skeleton were examined in 125 patients both radiologically and by scanning, using 99mTc-pyrophosphate. The results are compared, particular attention being paid to errors in diagnosis. The figures show that scans represent a valuable additional form of examination for detecting tumours which have not been found radiologically. The importance of serial observations is discussed.
