Objective: To investigate differences in arterial involvement patterns on F-FDG PET-CT between predominant cranial and isolated extracranial phenotypes of giant cell arteritis (GCA).
Methods: A retrospective review of F-FDG PET-CT findings was conducted on 140 patients with confirmed GCA. The patients were divided into two groups: the cranial group, which presented craniofacial ischemic symptoms either at diagnosis or during follow-up, and the isolated extracranial group which never exhibited such manifestations.
Article Synopsis
- This study aims to evaluate how effective F-FDG PET-CT scans are for detecting large-vessel involvement in patients suspected of having giant cell arteritis (GCA) who have negative results from temporal artery biopsies (TAB).
- Researchers looked at 127 patients and found that F-FDG PET-CT scans were positive in 61 out of 73 patients finally diagnosed with GCA, resulting in a high sensitivity of 83.5% and good specificity of 85.1%.
- The findings suggest that F-FDG PET-CT is a useful diagnostic tool in identifying large-vessel involvement in GCA cases, especially in patients with negative TAB results.
