High performance of low-dose ultrahigh-resolution photon-counting detector CT for sacroiliac joint assessment in axial spondyloarthritis

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 an...

Performance of Photon-counting CT for Assessing Pretreatment Breast Cancer: Comparison with Mammography, MRI, and 18F-FDG PET/CT.

Background Photon-counting CT (PCCT) offers improved spatial resolution, contrast to noise ratio, and dose efficiency, but its clinical utility remains incompletely defined for breast cancer. Purpose To evaluate the feasibility of PCCT for pretreatment breast cancer assessment through comparisons with MRI, full-field d...
