摘要 目的研究冠状动脉追踪冻结技术(SSF)采用前瞻性心电门控扫描与同期DSA成像的比较。方法共纳入80例行SSF和DSA成像的冠心病患者,平均心率(75.6±8.2)次/min,均不服用降低心率药物,支架置入29例(36.25%)。SSF采用美国GE 64排128层冠脉Optima CT680扫描机和GE AW4.6 Advantage workstation后处理工作站,前瞻性心电门控扫描,比较SSF与DSA成像评估冠脉粥样斑块和管腔狭窄程度的价值。结果 SSF成像各组不同心率显示斑块数目、管腔狭窄程度以及管腔狭窄≥75%数目比较均无差异(P>0.05);DSA与SSF成像在≤65次/min和65~85次/min组管腔狭窄程度以及管腔狭窄≥75%数目比较无差异(P>0.05),但是>85次/min组DSA成像较SSF显示管腔狭窄程度以及管腔狭窄≥75%数目明显增加,差异有统计学意义(P<0.05)。结论在心率<85次/min SSF采用前瞻性心电门控扫描与同期DSA成像在显示粥样斑块数目和管腔狭窄程度上价值相当。
