A method based on image quality criteria (QC) for cine-angiography was developed to measure the quality of cine-angiograms (CA). A series of 30 CA for left ventriculography (LV) and left and right coronary angiography (LCA, RCA) have been scored and 172 readings were obtained. Standard deviation of quality scores indicated the reproducibility of the method. Each part of CA was examined separately, giving scores for LV, LCA and RCA and a total score (TS), with clinical (C) and technical (T) criteria defined and examined separately. In 83% of the studies TS was >0.8 and with standard deviation from 0.02 to 0.21. In general, LV had a lower score and greater disagreement compared with RCA and LCA. Disagreement was greater in T, compared with C. In conclusion, these results indicate that QC, translated into a scoring system, yields reproducible data on the quality of cardiac images.
开发了一种基于电影血管造影图像质量标准（QC）的方法来测量电影血管造影片（CA）的质量。对一系列30张用于左心室造影（LV）以及左、右冠状动脉造影（LCA、RCA）的CA进行了评分，共获得172个读数。质量评分的标准差表明了该方法的可重复性。对CA的每个部分分别进行检查，给出LV、LCA和RCA的分数以及总分（TS），并分别定义和检查临床（C）和技术（T）标准。在83%的研究中，TS>0.8，标准差为0.02至0.21。一般来说，与RCA和LCA相比，LV的分数较低且差异较大。与C相比，T中的差异更大。总之，这些结果表明，转化为评分系统的QC可产生关于心脏图像质量的可重复数据。
