Fig. 2From: Application of deep learning reconstruction of ultra-low-dose abdominal CT in the diagnosis of renal calculiCT images from an 81-year-old female patient with a clinically suspected renal calculus. A left renal calyceal calculus 1.9 mm in diameter was detected on all the three images. However, LD-HIR (a) was clearest, followed by ULD-DLR (c), while ULD-HIR (b) was the least clear. LD-HIR means low-dose computed tomography with hybrid iterative reconstruction. ULD-HIR means ultra-low-dose computed tomography with hybrid iterative reconstruction. ULD-DLR means ultra-low-dose computed tomography with deep learning reconstructionBack to article page
