Dual-Source CT Angiography of Peripheral Arterial Stents: In Vitro Evaluation of 22 Different Stent Types

Table 2

Mean visible lumen diameters and intraluminal attenuation of the investigated stents using four different reconstruction kernels. Diameters of the visible stent lumen are given as mean (minimum/maximum) ± standard deviation in % of the actual lumen. Attenuation and noise values are given as mean (minimum/maximum) ± standard deviation in Hounsfield units (HUs).
