Reversal of flow in the pulmonary artery: High-pitch spiral as a new method for dose reduction in functional imaging
Journal of Cardiovascular Computed Tomography, 06/22/2012
Boswell GF et al. – Advancements in CT technology lave led to substantial dose reductions for anatomic imaging of the heart. Here authors illustrate an example where rapid repeat imaging with a high pitch spiral technique can image physiologic function. By optimal timing, and repeat sub second scanning, they illustrate an unusual case where direction of blood flow in the right pulmonary artery is reversed.
