A wide variation in patient exposure has been observed in interventional radiology and cardiology. The purpose of this study was to investigate the patient dose from fluoroscopy-guided procedures performed in non-academic centres when compared with academic centres. Four procedures (coronary angiography, percutaneous coronary intervention, angiography of the lower limbs and percutaneous transluminal angioplasty of the lower limbs) were evaluated. Data on the dose-area product, fluoroscopy time and number of images for 1000 procedures were obtained from 23 non-academic centres and compared with data from 5 academic centres. No differences were found for cardiology procedures performed in non-academic centres versus academic ones. However, significantly lower doses were delivered to patients for procedures of the lower limbs when they were performed in non-academic centres. This may be due to more complex procedures performed in the academic centres. Comparison between the centres showed a great variation in the patient dose for these lower limb procedures.
在介入放射学和心脏病学领域，已观察到患者受辐射剂量存在很大差异。本研究的目的是调查与学术中心相比，非学术中心进行的透视引导手术对患者的剂量。评估了四种手术（冠状动脉造影、经皮冠状动脉介入治疗、下肢血管造影和下肢经皮腔内血管成形术）。从23个非学术中心获取了1000例手术的剂量面积乘积、透视时间和图像数量的数据，并与5个学术中心的数据进行了比较。非学术中心与学术中心进行的心脏病学手术未发现差异。然而，在非学术中心进行下肢手术时，患者接受的剂量明显较低。这可能是由于学术中心进行的手术更为复杂。各中心之间的比较显示，这些下肢手术的患者剂量存在很大差异。
