High-resolution computed tomography (HRCT) is a proved imaging modality for use in assessment of infiltrative lung disease. Findings suggestive of infiltrative lung disease on HRCT scans include ground-glass attenuation, consolidation, nodules, and interlobular septal thickening. Similar patterns, however, may be caused by various vascular abnormalities including regional or diffuse increase in blood flow, pulmonary edema, pulmonary hypertension, and thromboembolism. A correct diagnosis can usually be made by careful analysis of the pulmonary vasculature. Parenchymal abnormalities of vascular origin are associated with increased or decreased vessel diameter, vascular compression, or intraluminal filling defect.
高分辨率计算机断层扫描（HRCT）是一种已被证实可用于评估浸润性肺病的成像方式。HRCT扫描上提示浸润性肺病的表现包括磨玻璃样衰减、实变、结节和小叶间隔增厚。然而，类似的表现可能由各种血管异常引起，包括局部或弥漫性血流增加、肺水肿、肺动脉高压和血栓栓塞。通常通过仔细分析肺血管系统可做出正确诊断。血管源性的实质异常与血管直径增加或减少、血管受压或管腔内充盈缺损有关。
