Fig 1
CTCA images of left anterior descending artery.
A: Image with a qualitative quality score of 4 with ATCM and strong AIDR3D, excellent attenuation of vessel lumen and clear vessel wall definition with barely perceived image noise. B: Image with a qualitative quality score of 3 with ATCM and FBP, good attenuation of vessel lumen and well-maintained vessel wall definition with minimal image noise.
