IS Case 295: Right to left shunt with pulmonary hypertension

Publication Date: 2009-08-05
On VQ scan, the finding of radiotracer uptake in the kidneys on perfusion images is consistent with a right to left shunt. When a shunt exists, there is immediate renal activity, best seen on posterior and lateral views. Additional findings with shunting in a VQ scan would include uptake in the brain, but, since this study was not specifically performed to evaluate for shunt, imaging of the brain was not performed.
