病史 Patient History 女性、50岁。阵发性胸痛1月,合并左室肥厚。血管迷走神经负荷后,进行胸痛三联检查。 A woman in her 50s, complaining of paroxysmal chest painfor one month and presenting with left ventricular hypertrophy, was referred to CT for triple-rule-out after a vasovagal episode related to stress.

结论 由于拥有160mm的探测器宽度,胸痛三联检查仅使用2个轴扫即可很好的观察肺动脉、胸主动脉以及无运动伪影的冠状动脉。使用新一代的迭代重建ASiR-V,只用0.5 mSv的射线剂量便得到很好的图像质量。(图2)。 Thanks to the 160 mm coverage, this exam was performedwith two axial volumes for optimal visualization of pulmonary arteries,thoracic aorta and motion free coronaries. The new generation of iterativereconstruction ASiR-V delivers diagnostic image quality at half a milliSievert.

Jean-Louis Sablayrolles 医生的评价 “Revolution CT的胸痛三联检查,可以在一次对比剂注射及低射线剂量下完成,简便稳定、可重复性好,各部位对比剂均匀,图像质量完美。” With Revolution CT, Triple-Rule-Out studies are now robustand reproducible with easy synchronisation with contrast injection and lowerdose, with uncompromised image quality.
