dc.description.abstract | This study was carried out to measure diameters of stents within phantom and to know proper algorithm for evaluating patency of stent by using multi-detector computed tomography (MDCT). Phantom model that stent was located in plastic pite with mixed saline and contrast (10:1) and total 80 patients (man:woman = 53:27, mean age, 60.8 years old) who undertaken percutaneous coronary intervention (stenting) were included in this study. Computed tomography scans were performed with 16- and 64-slice MDCT scanner with retrospective electrocardiography gating. Standard scanning protocols were applied. Cardiac radiologist and radiologic technician measured internal diameters of stents. Also, image qualities of stents as 8 points were scored. For evaluation of images,window width and window center were used as 900±100 and 400±100, respectively. In phantom model, average maximal diameters measured by each algorithms were 2.35 mm (B50f in Siemens AG, Medical Solutions [S company]) and 2.53 mm (Xres standard [XCB] in Phillips Medical Systems [P company]), respectively. In patients, in-stent resolution processed by Xres sharp (XCC)was scored as 7.67 (highest). In this study, B40f, B50f (16 slice MDCT in S company), XCB and XCC (64 slice MDCT in P company) are appropriate algorithms for evaluating internal patency of stents. | - |
