Technetium-99m-HMPAO Labeled Leukocyte Single Photon Emission Computerized Tomography (SPECT) for Assessing Crohn's Disease Extent and Intestinal Infiltration

Abstract

(99m)Tc-HMPAO labeled leukocyte SPECT provides a more detailed visualization of CD lesions than planar images. This technique may better discriminate between intestinal and bone marrow uptake, thus being useful for assessing CD lesions within the pelvis, including perianal disease.
