Fig. 4From: Convolutional neural network-based automatic heart segmentation and quantitation in 123I-metaiodobenzylguanidine SPECT imagingRelationships between washout rates calculated from SPECT images using CNN and planar images using conventional methods: linear regression lines (upper panels) and Bland–Altman plots (lower panels). SPECT WR vs. planar WRBC (A), planar WRNC (B), and planar WRHMR (C). Shaded area, confidence of fit; dotted lines, 95% confidence intervalsBack to article page
