Abstract

Background Pulmonary embolism (PE) is a serious condition and has a clinical dilemma in diagnosis. Computed tomography pulmonary angiography (CTPA) is a gold standard in its diagnosis, but MRI has proven a good role in PE diagnosis. Aim The aim of this work was to evaluate the role of noncontrast magnetic resonance pulmonary angiography (MRPA) imaging in diagnosis of acute PE using CTPA as a gold standard. Patients and methods In total, 25 patients with PE confirmed by CTPA were included in this study. All patients underwent computed tomography angiography and noncontrast MRPA on the same day or within three consecutive days. The results were compared and statistically analyzed. Results The mean age of the study group was 46.4 ± 13.5 years. Females represent 60% (15/25) and males represent 40% (10/25). The per-vessel sensitivity of noncontrast MRPA reached to about 100% with specificity 100% at the level of the main trunk, right and left main pulmonary arteries down to segmental arteries. The sensitivity for right subsegmental branches was 25% and left subsegmental branches was 33.3%. Conclusion The noncontrast MRPA has a reasonable sensitivity and specificity in the diagnosis of PE, especially in major branches. So, it can be used as an alternative to the computed tomography angiography, especially when the computed tomography angiography and the use of gadolinium are contraindicated.
非对比磁共振肺成像在肺栓塞诊断中的作用
肺栓塞(PE)是一种严重的疾病,临床诊断困难。ct肺血管造影(CTPA)是其诊断的金标准,但MRI已被证明在PE诊断中具有良好的作用。目的以非对比磁共振肺血管造影(MRPA)为金标准,评价其在急性PE诊断中的作用。患者与方法本研究共纳入25例经CTPA确诊的PE患者。所有患者在同一天或连续三天内接受了计算机断层血管造影和非对比MRPA检查。对结果进行比较和统计分析。结果研究组患者平均年龄46.4±13.5岁。女性占60%(15/25),男性占40%(10/25)。在主干、左右肺动脉主干至节段动脉水平,非对比MRPA的单支敏感性可达100%左右,特异性为100%。右亚节段分支敏感性为25%,左亚节段分支敏感性为33.3%。结论非对比MRPA对PE的诊断具有合理的敏感性和特异性,尤其是对大分支PE的诊断。因此,它可以作为计算机断层血管造影的替代方法,特别是当计算机断层血管造影和钆的使用是禁忌的时候。
