Leukocyte scintigraphy is a medical imaging test which displays the distribution of radiolabeled (for example labeled with 111In indium) leukocytes in the body to detect infection / inflammation. Whole-body scintigrams, and/or images of specific anatomic regions are recorded. Additionally, single photon emission computed tomography can be obtained.
