Parameters Influencing PET Imaging Features: A Phantom Study with Irregular and Heterogeneous Synthetic Lesions

<div>The seven different configurations to obtain lesions with different heterogeneous uptake. C<sub>1</sub>, C<sub>2</sub>, and C<sub>0</sub> represent areas with lower, higher, and no radioactivity concentration, respectively. (a–c) Strategies for reproducing necrotic tissue; (d, e) heterogeneous (multifocal) uptake; (f, g) heterogeneous uptake and necrotic tissue.</div>
