Intralobar bronchopulmonary sequestration evaluated by contrast-enhanced three-dimensional MR angiography

Bronchopulmonary sequestration (PS) is characterized by non-functioning lun g tissue fed from one or several aberrant systemic arteries. The condition is diagnosed by visualizing the feeding arteries using non-invasive CT,MRI, colour Doppler sonography or conventional angiography. We present a 5-year -old boy in whom intralobar sequestration was diagnosed using contrast-enha nced 3D MR angiography, which visualised fine blood vessels in the thoraco- abdominal region without arterial puncture. This technique is useful for di agnosing PS.
