**11.6. Molecular imaging**

Potential techniques include bioluminescence and radiolabeled antibodies or leukocytes, to target bacteria, biofilms, fibrin, and sites of inflammation. Bioluminescence requires optical imaging, while radiolabeling uses PET, SPECT, or combined modalities [140]. These experimental techniques may have applications such as detection of infected vascular grafts or intracardiac infection [136].
