Abstract
Respiratory motion is known to cause blurring in Single‐Photon Emission Computed Tomography (SPECT) images which can mask or mimic disease. Pediatric imaging with 99mTc‐labeled dimercaptosuccinic acid (DMSA) is used to assess cortical defects in kidneys and may be especially susceptible to artifacts introduced by respiratory motion due to the thin kidney cortices and small kidney volumes seen in many pediatric patients.
