Contrast recovery coefficient of cold spheres (\({Q}_{c}\)) as function of total effective 99mTc activity. \({Q}_{c}\) computed on 99mTc images acquired in presence of different 99mTc activities. Results are displayed as function of the total effective 99mTc activity in the phantom. Panel A refers to cold sphere S1 and panel B to cold sphere S2. Blue circles refer to measurements acquired in presence of 99mTc only, while green triangles represent measurements acquired in presence of both 99mTc and 166Ho
