Assessment of image quality and dose in contrast-enhanced head and neck CT angiography of New Zealand rabbit.

CONCLUSIONS: Low dose CTA of rabbits with 70 or 80 kVp is feasible in a 256-slice or a 64-slice CT scanner. The radiation dose from the 256-slice CTA was much lower than that from the 64-slice CTA with comparable SNR and CNR. The technique can be further applied in longitudinal monitoring of an animal stroke model in the future. PMID: 32597826 [PubMed - as supplied by publisher]
