ResumoSystemic to pulmonary shunts are done to improve systemic oxygen saturation and accelerate the development of the pulmonary arteries in neonates and infants with congenital cyanotic heart disease and diminished pulmonary blood flow. Assessment of the shunt graft usually requires invasive angiography. Spiral computed tomography (CT) is a non-invasive technique to produce three-dimensional angiographic images which can be viewed from any perspective. 1 Kalender WA Seissler W Klota E Vock P Spiral volumetric CT with single-breath-hold technique, continuous transport, and continuous scanner rotation.
