Article Synopsis
- CT perfusion studies increase local radiation exposure due to repeated scanning of the same area on a patient's head.
- A new ultra-low-dose technique using a quantum de-noising filter has shown to reduce noise by two-thirds, while preserving image quality.
- This low-dose protocol achieved a 68% reduction in radiation dose compared to the standard method, indicating its effectiveness in improving safety and image clarity in CT perfusion studies.
