病史 Patient History 男性、60岁。下肢动脉病变CT随访。
A man in his 60s was referred to CT for follow-up of lower limb arteriopathy.
Revolution CT采集参数
结论 该病历显示:对于严重的动脉疾患,高空间分辨率检查使诊断更具信心。ASiR-V技术明显的降低了射线剂量,在得到高图像质量的前提下,全下肢检查DLP仅为226mGy*cm。(图1)。 This exam demonstrates the need of high spatial resolution for a confident diagnosis in severe arteriopathy cases. The significant dose reduction capabilities of ASiR-V allowed us to get this high image quality atonly 226 mGy*cm. 图1: 高清下肢CT 血管成像
Jean-Louis Sablayrolles医生的评价 “ Revolution CT在血管检查中可采用多种灵活的模式,包括多个容积轴扫或80mm准直的螺旋扫描。先进的ASiR-V技术,可以在低剂量的情况下得到完美的图像。” Revolution CT provides the flexibility to perform vascular examination using multi-volume axial imaging or helical mode with up to 80 mm collimation to optimise the results while delivering low dose thanks to ASiR-V.
