Noise reduction and image quality improvement of low dose and ultra low dose brain perfusion CT by HYPR-LR processing.

Noise reduction and image quality improvement of low dose and ultra low dose brain perfusion CT by HYPR-LR processing.

PURPOSE: To evaluate image quality and signal characteristics of brain perfusion CT (BPCT) obtained by low-dose (LD) and ultra-low-dose (ULD) protocols with and without post-processing by highly constrained back-projection (HYPR)-local reconstruction (LR) technique. METHODS AND MATERIALS: Simultaneo...
