TUMOUR
For the evaluation of the acquired images, qualitative visual analysis was used to determine the presence/absence and the number of lesions identified by scintigraphy based on abnormal tracer uptake (defined as clearly discernible uptake above background concentration—regional blood pool). The number and identity of the lesions with increased abnormal uptake detected per verifiable organ or body region relative to those detected by conventional imaging were assessed. Identification of the time points p.i. with the highest observed number of lesions and the highest tumour/background ratios for both 10 and 50 μg mass amounts was performed to evaluate the influence of mass amount on tumour and normal organ uptake. In all clinical centres, the scintigraphy scans were evaluated by two experienced nuclear medicine specialists.
