Table 1. Summary of advantages and disadvantages of CT perfusion.

Categories	Advantages	Disadvantages
Static CTP	CT coronary angiography and CT perfusion with single data set	Qualitative and semi-quantitative CTP analyses only
	Rapid analysis	Susceptible to artifacts
	Less dependent on specific vendor technology	Timing of acquisition essential
	Most data on diagnostic accuracy and outcomes
	Lower radiation dose
Dynamic CTP	Qualitative, semi- and fully quantitative (mL/min/gram) measurements possible	Long breath hold
	Ability to observe first pass of myocardial perfusion, which may help mitigate some artifacts	More susceptible to patient and cardiac motion artifacts
	Timing less critical than static CTP	Higher radiation dose
		Increased image noise (due to multiple data sets being acquired)
		Longer and more complex analysis
