Ray spectra of the eluted "mTc (T,,, = 6.02 h) and of the spent "MO generators (T,,, = 65.9 h) have been measured using a high-resolution y-ray spectrometer. Analysis of the measured spectra have shown that together with the 140.5 keV y-ray line of the %Tc, other y-ray lines resulting from other rad
A total of 34 99mTc-generators from eight different manufactures were studied in 1974 and 1975 with regard to their performance and to the quality of the eluates. With some exceptions the generators performed well and proved their ability to act as a reliable source of 99mTc-pertechnetate. Two cases
At irregular intervals, a 99mTc-labelled microcolloid for liver and spleen scintigraphy was reported to accumulate in the lungs, in the absence of any pathophysiological condition usually associated with this phenomenon. These findings were in direct contrast to the results obtained during quality c
