Application of 64-layer spiral CT pulmonary angiography in the diagnosis and prognosis evaluation ofpulmonary embolism
64层螺旋CT肺动脉造影在肺动脉栓塞诊断及预后评估中的应用

摘要

目的 探究64层螺旋CT肺动脉造影（CTPA）在肺动脉栓塞诊断价值及预后评估中的应用效果。方法 筛选自2020年3月1日-2022年2月28日，由我院接收并实施诊疗的肺动脉栓塞患者53例作为参与者纳入本次研究。所有参与者均先后实施64层螺旋CT肺动脉造影展开检查，其中13例患者同时展开数字减影血管造影（DSA）检查。结果 CTPA分析的累及支数177例，占比31.83%，而DSA分析的累及支数70例，占比12.59%。二者相比，CTPA的准确率更高。结论 针对肺动脉栓塞患者而言，64层螺旋CT肺动脉造影能够清楚的显示出病灶情况及累及范围，为医师制定方案及后续展开治疗提供有力参考及依据，是一种应用价值较高且实用性较强的检测方法。

Abstract

Objective to evaluate the value of 64-slice spiral CT pulmonary angiography (CTPA) in the diagnosis and prognosis of pulmonary embolism (PE) .
Methods from March 1,2020 to February 28,2022,53 patients with pulmonary embolism were enrolled in this study. 64-slice spiral CT pulmonary angiography was performed in all patients, and digital subtraction angiography (DSA) was performed in 13 patients.
Results 177 cases (31.83%) were involved by CTPA, while 70 cases (12.59%) were involved by DSA. Compared with CTPA, the accuracy of CTPA is higher.
Conclusion   for patients with pulmonary embolism, 64-slice spiral CT pulmonary arteriography can clearly show the lesion and the involved range, which provides a strong reference and basis for doctors to make plans and carry out follow-up treatment, it is a detection method with high application value and strong practicability.
