核素肺灌注显像属于功能影像,是较早用于肺部疾病诊断的影像学方法,依据肺血流受损的分布特点诊断疾病和判断病情的严重程度,可以一目了然地反映肺部的整体病变,具有灵敏、直观等优点。笔者分析了2例行核素肺灌注显像患者的资料,与肺动脉造影和右心导管结果进行对比,并通过文献复习探讨肺动脉炎肺灌注显像的临床及影像学特征,以提高对该病的认识和诊断。
肺动脉炎肺灌注一侧不显影2例
Two cases of pulmonary arteritis with pulmonary perfusion imaging unilateral absence
-
摘要: 笔者报道了2例肺灌注显像一侧不显影的病例。结合临床症状、实验室检查、影像学资料及肺动脉造影结果,考虑肺动脉炎。肺灌注显像是很好的肺动脉炎检测工具,在评估疾病严重程度、指导临床决策方面有着重要意义,同时在随访及疗效评价方面有着不可替代的作用。Abstract: The author reports two cases of unilateral absent pulmonary perfusion imaging. On the basis of clinical symptoms, laboratory tests, imaging examinations, and pulmonary angiography, the patients were diagnosed with pulmonary arteritis. Pulmonary perfusion imaging can be used as a good testing tool for pulmonary arteritis and has important significance in assessing disease severity and directing further management. This tool plays an irreplaceable role in follow-up and curative effect evaluation.

图 1 患者女性,41岁,肺动脉球囊扩张术治疗前后CTPA、肺灌注及肺动脉造影图像 图中,A~D:术前图像,术前CTPA VR图像(A)示右肺动脉狭窄,远端分支稀疏;99Tcm-MAA肺灌注图像(前位及右前斜位)(B~C)示右肺未见血流灌注,左肺呈“倒鞋底征”改变;肺动脉造影图像(D)示右肺动脉次全闭塞。E~H:术后图像,术后CT肺动脉成像VR图像(E)、99Tcm-MAA肺灌注图像(前位及右前斜位)(F~G)及肺动脉造影(H)图像,右下肺动脉经肺动脉球囊扩张术后造影示右下肺动脉显影,右肺下叶血流灌注明显改善。CTPA:CT肺血管成像;VR:容积再现;MAA:聚合白蛋白。
