Spondylodiscitis.

Diagnosis of spondylodiscitis remains a challenge for clinicians. It results from various causative agents and conditions that can be challenging to identify. Prompt and appropriate treatment are necessary to prevent long-term irreversible complications and sequelae.

Role of FDG PET/CT in bacteremia and fever of unknown origin: a pictorial overview of finding the culprit.

F fluorodeoxyglucose ([F]FDG) positron emission tomography/computed tomography (PET/CT) has established itself as a critical diagnostic tool in the evaluation of patients with bacteremia and fever of unknown origin (FUO), particularly following futile conventional investigations. These conditions are often challenging due to diverse underlying etiologies, including infections, inflammatory conditions and malignancies. PET/CT has the advantage of being a whole-body imaging technique with high sensitivity for detecting areas of increased metabolism often associated with infection or inflammation.

FAPI PET in the Management of Lung Tumors.

Fibroblast activation protein (FAP), selectively expressed on activated fibroblasts in proliferating tissues, is emerging as a promising target in oncology. In lung cancer, the leading cause of cancer-related deaths worldwide, [F]FDG PET/CT has set the bar high and earned widespread recognition in clinical guidelines for its essential role in staging and follow-up. Yet, FAP-targeted imaging agents like FAPI PET/CT have demonstrated significant potential due to their high tumor specificity, rapid tracer uptake, and low background activity.
