摘要
目的探讨螺旋CT在肺动脉栓塞(PE)以及下肢深静脉血栓形成中的成像技术及对栓子的诊断价值。方法选择2011年4月—2012年2月的24例PE患者〔其中包括10例深静脉血栓(DVT)患者〕,分别采用4层和16层螺旋CT进行肺动脉和下肢静脉的联合成像检查技术,比较不同的扫描条件及后处理技术对于栓子、周围动脉和静脉的显示能力。结果与4层螺旋CT比较,16层螺旋CT发现22例PE患者,计栓子77处,栓子均显示清晰;DVT 10例,计栓子36处。延迟90s时,两种扫描方法比较,差异有统计学意义(P<0.05);延迟120s、180s、240s时,两种扫描方法比较,差异均无统计学意义(P>0.05)。结论 4层及16层螺旋CT联合扫描对肺动脉血栓和深静脉血栓诊断,具有重要的临床意义;尤其16层螺旋CT,在对PE和DVT联合扫描中,静脉成像延迟扫描时间以120s～180s最佳,为PE和DVT的治疗提供了有益的诊断。
Objective To explore the diagnostic value of helical CT in the imaging technique and emboli for pulmonary embolism（PE） and deep venous thrombosis.Methods 24 cases of PE in patients[including 10 cases of deep vein thrombosis（DVT） patients] from April 2011 to February 2012 were chosen.They were taken with 4-slice and 16-slice spiral CT pulmonary artery and lower extremity venous joint imaging technology.The displays of the emboli,peripheral arterial and venous of different scanning conditions and post-processing techniques were compared.Results With 4 slice spiral CT,16 layer spiral CT findings of 22 PE patients,77 meter of emboli,emboli are clear display;10 cases were DVT,36 meter of emboli;90s gauge emboli;delay,the two scanning methods comparison,the difference was statistically significant（P0.05）;120s,180s,240s delay,the two scanning methods comparison,there were no significant differences between them（P0.05）.Conclusion 4 and 16 spiral CT scan has an important clinical significance in the diagnosis of pulmonary artery thrombosis and deep vein thrombosis.About 16 spiral CT the joint scan of PE and DVT,venous imaging delay scan time was best in 120s to 180s,and provides a useful dignosis of help for the treatment of PE and DVT.
