Fig. 6From: Evaluation of two intraoperative gamma detectors for assessment of 177Lu activity concentration in vivoThe ratio between the number of counts over the tumour sphere (C T ) and that over the background (C Bgr) vs. the diameter of the tumour sphere, C T /C Bgr, was generally higher for detector B than for detector A. The stars indicate the combinations of T/Bgr and tumour sphere size where a statistically significant difference (p < 0.05) between C T and C Bgr could be detectedBack to article page
