Thoracic interventional radiology in children.

Significant technological advancements have been achieved in radiology with the introduction of a branch speciality known as interventional radiology. Radiology has moved into the therapeutic arena, performing minimally invasive diagnostic and therapeutic procedures. The interventional radiologist can treat certain vascular and non-vascular conditions with "keyhole" or perhaps more correctly "pinhole" techniques using catheter-based technology directed under image guidance with X-ray (including computed tomography), ultrasound and magnetic resonance imaging. Interventional radiology can provide new treatment options for children not possible a few years ago.
