摘要目的比较自适应统计迭代重建(ASiR)和滤波反射重建技术(FBP)用于体质量≥91kg病人时的影像质量和辐射剂量。方法在这项机构审查委员会批准的回顾性研究中,对100例体质量≥91kg[91～181.9kg,平均(107.6±17.4)kg]的成人行单期对比增强腹部盆腔CT检查,由2名阅片者双盲进行ASiR和FBP影像质量的主观测量值和辐射剂量分析,影像质量使用主观标准化数值模拟和客观噪声来评估。
Abstract Objective To compare the image quality and radiation dose of Adaptive Statistical Iterative Reconstruction (ASiR) and Filtered Reflection Reconstruction (FBP) for patients with body mass ≥91 kg. Methods In a retrospective study approved by the Institutional Review Board, 100 patients with a mass of 91 kg or more (91 to 181.9 kg, mean (107.6 ± 17.4) kg] underwent single-phase contrast-enhanced abdominal pelvic CT examination consisting of 2 The reader was double-blind for both subjective and radiometric dose-to-mass analysis of ASiR and FBP image quality, which was evaluated using subjectively standardized numerical simulations and objective noise.
