Warranty period of coronary computed tomography angiography and [15O]H2O positron emission tomography in symptomatic patients
Main finding · Warranty periodResult — go to the resultDifference 2 yearsAuthors' conclusion
As standalone imaging, the warranty period for normal coronary CTA is ≥10 years, whereas patients with non-obstructive CAD have a warranty period of 5 years. Normal PET yielded a 2-year longer warranty period in patients with obstructive CAD.
