Figure 11a. (a) Coronary catheter angiogram obtained after insertion of a Radius stent (SciMED Live Systems, Maple Grove, Minn) (arrowheads) depicts a patent RCA. (b, c) Curved planar reformatted images obtained in two perpendicular planes from CT data clearly demonstrate patency of the mid-RCA with coronary stent insertion. Note that almost no streak artifacts or blooming artifacts are observed.
