Kawasaki disease (KD) is a systemic vasculitis syndrome of early child
hood. It involves particularly the coronary arteries and may cause ane
urysms and thrombotic occlusions. Echocardiography is the most useful
method of detecting coronary aneurysms. Nevertheless, obstructive lesi
ons are difficult to evaluate and often need invasive coronary angiogr
aphy. An important feature of this disease is the possibility of findi
ng coronary pathology several years after the onset. This characterist
ic makes KD an important cause of coronary artery disease (CAD) in you
ng adults. Thus patients with KD and previously diseased coronary arte
ries should be kept under long-term control. However, coronary angiogr
aphy is invasive and cannot be performed repeatedly, especially in you
ng patients. As an alternative, thallium 201 scintigraphy has been emp
loyed, but its low-energy photons are suboptimal for standard gamma-ca
mera imaging, particularly in children aged less than three years.
