13. Brain Scintigraphy
Luxury perfusion
Occurs when there is increased blood flow and reduced O2 in
brain tissue. Causes acute lactic-metabolic acidosis. Many different
disease states can cause this: CVA, trauma, tumor, etc.

42. Brain Scintigraphy
Non-patient Shunt
At 20 minutes following injection of tracer into the shunt reservoir, activity is seen in the proximal limb tubing only. At 40 minutes, activity is seen in the lateral ventricles, and third and fourth ventricles, as well as extending down the spinal canal. Still, no activity is seen in the distal shunt.
