Abstract
Elevation of the left or right hemidiaphragms due to postsurgical changes in anatomical relationships, diaphragmatic eventration, or congenital anatomic variations can result in “hot” and/or “cold” processing artifacts. A high right hemidiaphragm can cause processing artifacts affecting the septal, apical, and inferior myocardial wall segments. A high left hemidiaphragm can cause similar artifacts affecting the inferior and inferolateral myocardial wall segments. Cinematic evaluation of the raw projection images is helpful in detecting erratic diaphragmatic motion due to hiccups, talking, laughing, coughing, or snoring.
