Role and applications of [F]FDG PET/CT in the assessment of osteoarticular infection and inflammation - Part II.

[F]FDG PET/TC is an emerging tool in the evaluation of inflammatory arthropathies, characterised by their insidious course and clinical overlap. It allows detection of subclinical inflammation, assessment of systemic involvement and quantification of metabolic parameters useful in early diagnosis and therapeutic monitoring. In rheumatoid arthritis, it correlates with clinical indices (Disease Activity Score), serological markers (CRP, anti-citrullinated protein antibodies) and ultrasound findings, and facilitates the identification of complications such as cardiovascular and pulmonary involvement.

Role and applications of F-FDG PET/CT in the assessment of osteoarticular infection and inflammation - Part I.

F-FDG PET/CT has been positioned over time as a useful tool in the evaluation of osteoarticular infections, overcoming conventional explorations like MRI or bone scintigraphy in some indications. Its ability to provide functional and anatomical images simultaneously and its excellent resolution contributes to a more precise and personalised approach in the treatment of osteoarticular diseases such as spondylodiscitis. In addition, it has proven valuable in patients with suspected infection that is complex to diagnose or treat, improving detection in subclinical stages.

Asthma as an Inflammatory Reason of Tracheobronchial PSMA Uptake.

A 53-year-old man with persisting increased serum prostate-specific antigen level (9.53 ng/mL) and repeated negative prostate biopsies was referred for a PET/CT with 68 Ga-PSMA-11. The PET/CT revealed focal uptake in the prostate suggestive of localized prostate cancer.
