Figure 1 Example of a Patent Stent
Conventional coronary angiography (A) showed patency of a stent (Cypher, 3.0 x 18 mm) placed in the left circumflex coronary artery. (B and C) Two orthogonal curved multiplanar reconstructions obtained with 64-slice MSCT (Siemens Sensation, kernel B46f) are provided, also showing patency of the stent. MSCT = multislice computed tomography.

Figure 2 Example of In-Stent Restenosis
Conventional coronary angiography (A) showed in-stent restenosis in a stent (Taxus, 2.5 x 20 mm) placed in the second marginal branch of the left circumflex coronary artery (arrowhead). (B) A curved multiplanar reconstruction obtained with 64-slice MSCT (Siemens Sensation, kernel B46f) is provided. In the proximal part of the stent (arrowhead), a hypodense area can be observed, indicating the presence of in-stent restenosis. Abbreviations as in Figure 1.

Figure 3 Example of High-Grade In-Stent Restenosis
(A) A conventional coronary angiogram is provided showing the presence of high-grade in-stent restenosis in the proximal part of a stent (Taxus, 3.0 x 24 mm) placed in the left anterior descending coronary artery (arrowhead). (B) A curved multiplanar reconstruction obtained with 64-slice MSCT (Siemens Sensation, kernel B46f) shows the presence of a large obstructing hypodense lesion in the proximal part of the stent (arrowhead), indicating the presence of high-grade in-stent restenosis. Abbreviations as in Figure 1.
