Figure 4: Case example of original, expert observer and GAN-based registration of PET and CT angiography with SUVmax values.

Figure 4:

Hybrid CT angiography (grey blue) and 18F-NaF PET (red) of the left anterior descending (LAD) and left circumflex (LCx) coronary arteries of a 52-year-old man; unregistered (left), registered by expert observer (center) and by GAN-based nonlinear diffeomorphic registration (right). Manual and GAN-based registration have similar increase in standard uptake value (SUVmax) compared to unregistered PET/CT angiography.
