  1. D diffuse, B bilateral, F focal
  2. aIncreased uptake above adjacent background was considered abnormal
  3. bPositive MRI:
  4. • bone marrow (patients #1, 4, 8): non-specific heterogeneous T1w marrow signal
  5. • lungs (patient #2): basilar lung consolidation with moderate right and mild left pleural effusions
  6. • stomach (patient #3): area of asymmetric wall thickening and lack of enhancement
  7. • ocular muscles (patient #2): mild predominantly lateral rectus muscle thickening
