Abstract

OBJECTIVES: To compare the performance of low-dose (LD) ultrahigh-resolution (UHR) photon-counting detector (PCD) CT with energy-integrating detector (EID) CT for sacroiliac joint assessment in axial spondyloarthritis (axSpA). MATERIALS AND METHODS: This was a prospective randomized study. AxSpA patients were enrolled and assigned to LD or clinical dose (CD) groups. Patients underwent UHR PCD-CT…
