目的：评价不同机构、透视厂商和不同代次的儿童心导管镜在辐射剂量和图像质量方面的差异。人们对电离辐射潜在有害影响的认识不断提高，推动了荧光显微镜的技术进步，并更加关注优化荧光显微镜的性能。目前，人们对不同机构、透视设备供应商和/或设备代际间的剂量-图像质量关系的可变性了解甚少。我们在三个不同的机构评估了来自菲利普斯、西门子、通用电气和东芝的最新一代荧光显微镜，以及老一代菲利普斯荧光显微镜(发布日期为2003年)。使用拟人剂量评估体模测量辐射剂量，有效剂量以蒙特卡罗模拟估算的mSv为单位。图像质量幻影图像由三位盲人评审员按12分制打分。透视有效剂量为0.04~0.14 mSv/1000脉冲，综合图像质量评分为8.0±0.6~10.4±1.3。电影血管成像的有效剂量范围为0.17~0.57mSv/1000帧，图像质量评分为10.1±0.3~11.1±0.3。有效剂量与图像质量之间有一定的相关性(r=0.67，p=0.006)。老一代透视系统提供的剂量始终高于新一代系统(透视系统高2.3至3.5倍，电影血管造影术高1.1至3.4倍)，图像质量没有明显差异。技术进步显著提高了荧光镜的性能。比较供应商和机构的最新一代系统，我们发现剂量-智商关系中的可变性，并推测这反映了设备和机构的优化实践。
To evaluate differences in radiation dose and image quality across institutions, fluoroscope vendors and generations of fluoroscopes for pediatric cardiac catheterization. Increased recognition of the potentially harmful effects of ionizing radiation has spurred technological advances in fluoroscopes, as well as increased focus on optimizing fluoroscope performance. There is currently little understanding of variability in the dose-image quality relationship across institutions, fluoroscope vendor and/or generation of equipment. We evaluated latest generation fluoroscopes from Phillips, Siemens, GE and Toshiba, and an older generation Phillips fluoroscope (release date 2003) at three different institutions. Radiation dose was measured using an anthropomorphic dose-assessment phantom with effective dose in mSv estimated from Monte Carlo simulations. Image quality phantoms images were scored on a 12-point scale by three blinded reviewers. Fluoroscope effective doses ranged from 0.04 to 0.14 mSv/1000 pulses for fluoroscopy with associated composite image quality scores ranging from 8.0±0.6 to 10.4±1.3. For cineangiography, effective doses ranged from 0.17 to 0.57 mSv/1000 frames with image quality scores ranging from 10.1±0.3 to 11.1±0.3. There was modest correlation between effective dose and image quality (r=0.67, p=0.006). The older generation fluoroscope delivered consistently higher doses than the newer generation systems (2.3 to 3.5-fold higher for fluoroscopy; 1.1 to 3.4-fold higher for cineangiography) without appreciable differences in image quality. Technological advances have markedly improved fluoroscope performance. Comparing latest generation systems across vendors and institutions, we found variability in the dose-IQ relationship and speculate that this reflects both equipment and institutional optimization practices.
