Angiographic and PCCT CCTA measurement of in-stent stenosis.

Stent	Stenosis CCTA (%)	Stenosis angiography (%)	Difference (%)
Chrono	83.33	68.94	14.39
Coroflex Please	78.91	57.81	21.1
Endeavor	80.14	69.10	11.04
Promus Element Plus	86.61	67.62	18.99
Radius	75.67	53.80	21.87
Tantal Coronary	87.92	66.10	21.82

In each case, diameter stenosis is given in %. The difference is given as the absolute difference in %. The absolute difference is 18.20% ± 4.11%.

Abbreviations: CCTA = coronary CT angiography; PCCT = photon counting computed tomography.
