Nuclear imaging.

Nuclear imaging (scintigraphy) is a noninvasive diagnostic procedure that can provide complementary information to that obtained by radiography, CT, MRI, or ultrasonography. Nuclear imaging is based on physiologic distribution of radiopharmaceutical compounds within the body so that it allows assessment of organ functions. When digital image processing is employed, nuclear imaging can allow quantitative assessment of organ function. This article provides an overview of common nuclear imaging procedures used in veterinary medicine.
