In a study focusing on giant cell arteritis (GCA), PET scans were utilized as both a diagnostic and prognostic tool. The study followed over 100 GCA patients who underwent 18F-fluorodeoxyglucose (FDG) PET imaging, revealing that those with elevated FDG uptake at diagnosis were more prone to developing thoracic aortic aneurysms. The research, led by Lien Moreel, MD, from the University Hospitals Leuven, Belgium, emphasizes the potential of PET imaging at diagnosis to estimate the future risk of aortic aneurysm formation in GCA patients. The study, published in Annals of Internal Medicine, highlights the importance of early PET scans for diagnostic and prognostic purposes in GCA patients. The positive PET scan results were associated with a higher risk of incident thoracic aortic aneurysms, indicating the predictive value of PET imaging in assessing aortic complications in GCA patients. The study suggests the need for further research to establish clear guidelines for the follow-up and monitoring of GCA patients with positive PET scan results.
