• With dose modulation.

CT coronary angiography is reasonable to use as
one of the fi rst choice imaging modalities in the
evaluation of known or suspected coronary anoma-
lies. (Level of Evidence: C)

Class IIb
It may be reasonable in most cases to not only assess
the patency of bypass graft but also the presence of
coronary stenoses in the course of the bypass graft

or at the anastomotic site as well as in the native

coronary artery system. (Level of Evidence: C)

Class III

Use of CT angiography in asymptomatic persons as

a screening test for atherosclerosis (noncalcifi c

plaque) is not recommended. (Level of Evidence: C)

CT coronary angiography to follow up stent patency

cannot be recommended. (Level of Evidence: C)
