title: Diagnosis of pulmonary sequestration by magnetic resonance imaging.
abstract: Pulmonary sequestration, an uncommon congenital anomaly, is traditionally best diagnosed using arteriography; however, this is invasive and not without risk of morbidity and mortality. We report two patients with pulmonary sequestration diagnosed using magnetic imaging techniques. The first was a 22-year-old woman and the second a 17-year-old boy, both of whom presented with symptoms of cough and exertional dyspnea. Pulmonary sequestration was suspected from their chest radiographs. Magnetic resonance imaging and magnetic resonance angiography clearly demonstrated the aberrant artery arising from the aorta in a single noninvasive examination that did not require the use of contrast medium. We recommend magnetic resonance imaging as a safe, efficient, and noninvasive modality for the diagnosis of pulmonary sequestration.
