OBJECTIVE
Computed tomographic pulmonary angiography may be indeterminate in regions of slow arterial flow because of underlying lung disease. In this case, dynamic computed tomographic angiography of the pulmonary vasculature (dynamic CTPA) was used to confirm flow variation within the pulmonary arteries in regions of pulmonary fibrosis and excluded pulmonary embolism.
CONCLUSIONS
Dynamic CTPA successfully demonstrates flow variation within the pulmonary arteries and may be a useful adjunct to exclude pulmonary embolism in CTPA cases with questionable arterial filling defects.
目的
由于潜在的肺部疾病，计算机断层扫描肺血管造影在动脉血流缓慢的区域可能无法明确诊断。在这种情况下，采用肺部血管动态计算机断层扫描血管造影（动态CTPA）来确认肺纤维化区域内肺动脉的血流变化，并排除肺栓塞。
结论
动态CTPA成功地显示了肺动脉内的血流变化，在CTPA中动脉充盈缺损可疑的病例中，它可能是排除肺栓塞的有用辅助手段。
