From: FDG-PET/CT as a useful tool for disease activity assessment in large vessel vasculitis in childhood
Diffuse and prolonged TA. In patient #4 a MRI of thoracic vessels was performed. Axial and coronal T1-weighted postcontrast images with fat saturation show partly emphasised, partly thickened vessel walls of the ascending aorta, the aortic arch, the descending aorta and the supraaortic branches, in most areas mentioned before with pathological contrast agent uptake (a and c). Corresponding to this, FDG-PET/CT 3 years later showed a still indicated vessel-associated tracer storage in the wall of the ascending aorta and the aortic arch in the sense of a slight residual floridity (b and d)
