本研究的目的是探讨是否可以通过螺旋CT血管造影（SCTA）定量评估急性肺栓塞（PE）的严重程度。连续 36 名没有潜在心肺疾病且临床高度怀疑 PE 的患者在初次诊断时 (T0) 和初次治疗后 (T1；T1-T2 平均时间间隔：32 天) 接受了前瞻性薄准直 SCTA 和超声心动图检查。 CT 严重程度评分基于每个中央和外周肺动脉部分的阻塞表面百分比，使用 5 分制 (1: 40 mm Hg)。 SCTA 描述了所有患者在 T0 时出现急性肺栓塞，10 名患者在 T1 时血管内血栓完全消退。在 T0 时，22 名具有严重超声心动图征象的患者中，肺动脉床阻塞的平均百分比显着较高（56+/-13 vs 28+/-32%；p
The purpose of this study was to investigate whether the severity of acute pulmonary embolism (PE) could be quantitatively assessed with spiral CT angiography (SCTA). Thirty-six consecutive patients without underlying cardiopulmonary disease and high clinical suspicion of PE underwent prospectively thin-collimation SCTA and echocardiography at the time of the initial diagnosis (T0) and after initial therapy (T1; mean interval of time T1-T2: 32 days). The CT severity score was based on the percentage of obstructed surface of each central and peripheral pulmonary arterial section using a 5-point scale (1: 40 mm Hg). The SCTA depicted acute PE in all patients at T0 with complete resolution of endovascular clots in 10 patients at T1. At T0, the mean percentage of obstruction of the pulmonary arterial bed was significantly higher in the 22 patients with echocardiographic signs of severity (56+/-13 vs 28+/-32%; p
