In children, analysis of pulmonary vascularity can provide useful information about cardiac and noncardiac abnormalities. The abnormal vascular patterns encountered in children with heart disease include (1) active engorgement, (2) passive congestion, (3) diminished pulmonary blood flow, (4) cephalad redistribution, and (5) unequal blood flow. Familiarity with these various patterns enables the clinician to produce relevant differential diagnoses for each. With additional study of the cardiac chambers, great vessels, and other radiographic findings, a specific diagnosis may often be suggested.
对于儿童而言，分析肺血管情况可为心脏及非心脏异常提供有用信息。患有心脏病的儿童出现的异常血管模式包括：（1）主动充血；（2）被动淤血；（3）肺血流量减少；（4）血流向上重新分布；（5）血流不均。熟悉这些不同模式可使临床医生针对每种情况做出相关鉴别诊断。通过对心脏腔室、大血管及其他影像学表现进行进一步研究，通常可得出具体诊断。
