Leveraging the Potential of Ultra-High Resolution Photon Counting Detector CT Angiography of the Cerebral Vasculature by Using Low kVp and Sharp Kernels
To evaluate the impact of low kVp and sharp kernels on the image quality of UHR PCD-CTA of the cerebral vasculature.
Conducted image acquisitions at 90 kVp
Employed sharp kernels for image reconstruction
Assessed image quality improvements
Image quality of UHR PCD-CTA improved with 90 kVp acquisition
Sharp kernels enhanced overall image clarity
Findings indicate that using these methods leads to better visualization of cerebral vasculature
Abstract
Image quality of UHR PCD-CTA of the cerebral vasculature is improved with image acquisition at 90 kVp and image reconstruction with (very) sharp kernels.
