FDG-PET in Infection Imaging of Immuno-compromised Patients.

Infectious syndromes represent a monumental challenge in the management of immunocompromised patients, directly driving high rates of morbidity and critical mortality. This clinical cohort comprised oncological populations undergoing aggressive cytoreductive chemotherapy, end-stage renal disease patients dependent on specialized long-term dialysis access networks, and individuals undergoing treatment with advanced antiretroviral regimens. Because these individuals suffer from blunted or suppressed cellular immune mechanisms, standard structural imaging methodologies (such as standard digital radiography and cross-sectional computed tomography) exhibit prolonged diagnostic latency, frequently remaining negative or ambiguous during the crucial early windows of active pathogen replication.
