| 摘 要： | 目的:探讨16层螺旋CT肺血管造影术(MSCTPA)诊断肺动脉栓塞的临床价值。方法:对临床拟诊肺栓塞的46例患者行MSCTPA检查及后重建技术,后重建方法包括容积再现(VR)、多平面重建(MPR)、最大密度投影(MIP)。结果:46例共发现栓子698个,其中肺动脉主干4个,左右肺动脉41个,叶动脉114个,段及亚段动脉539个。直接征象:①)血管截断征,表现为肺动脉管腔完全闭塞;②轨道征,表现为腔内充盈缺损位于血管中央,周围有对比剂环绕;③偏心性充盈缺损,表现为管腔内不规则充盈缺损偏向管壁一侧,边缘欠光整;④附壁性充盈缺损。间接征象:①肺窗观察见局限性的血管纹理稀疏,呈"马赛克征";②肺梗死,表现为肺外围以胸膜为基底的楔形或条状实变影;③胸腔积液、肺动脉高压、右心室肥大以及心包积液等。结论:MSCTPA能对肺动脉栓塞作出准确诊断,是无创、快速、安全、敏感的检查方法,并可追踪复查,评估治疗效果。 |
