Comparison of coronary CT angiography and MR imaging in the diagnosis of KD

Technique	Advantages	Disadvantages	When to use
Coronary CT angiography	Fast	Uses ionising radiation	Initial diagnostic work-up in patients with inadequate acoustic window
	Wide availability
	Excellent spatial resolution
	High sensitivity and specificity for detection of coronary abnormalities, including distal segments
MR imaging	No ionising radiation	Relatively long examination times	Follow-up in patients with known CAA and with inadequate acoustic window
	Excellent temporal resolution	Low spatial resolution	Potential role as complementary examination in the assessment of cardiovascular non-coronary complications
