Abstract

The most common mediastinal condition detected on MPI projection data is hiatal hernia. Hiatal hernias may be “hot” when containing refluxed bile or “cold” when containing nonradioactive fluid or food, and can be a source of SPECT MPI artifact given proximity to the heart. Malignant mediastinal masses (e.g., thymoma) typically appear “hot.”
