[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.

[Therapy verification film for field control during cobalt-60 radiotherapy].

The therapy-verification-film RP/V X-omat, which the Society Kodak produces, is a gamma ray sensible film, which because of its relative non-sensibility by irradiation of about 25-150 r, presents a density of S =0,7 to S = 3,9 and is good exploitable. Therefore, it is appropriated to the field controls during the radiotherapy especially for the mantel field technique. It represents a good complement of the gamma ray sensible film RPTL.
