Spectral photon-counting CT in first-pass myocardial perfusion imaging for very high-risk patients: a comparison with dual-energy CT
SPCCT and DECT showed comparable performance for MPI at rest in very-high-risk patients. The differences between normal and hypoperfused segments were of 17 HU and 16 HU on conventional images for DECT and SPCCT. SPCCT showed higher interobserver agreement compared to DECT, suggesting improved reproducibility.
