Image Errors on Planar and SPECT Studies
| Minor finding | Major finding |
| Missing labels: directional, study, view, image | Patient identification missing or incorrect |
| Study-specific parameters missing (e.g., time or % of gastric-emptying meal consumed) | Dynamic study acquired incorrectly; flow study not done, missed, early, or late |
| Processing forms or worksheets missing or incomplete | Wrong collimator used; study not interpretable |
| Date of study missing or incorrect | Incorrect isotope window used; study not interpretable |
| Region of interest too large, too small, or mislocated but does not cause incorrect interpretation | Area of interest out of camera field of view (poor positioning) |
| Generated data missing or not labeled correctly | Region of interest too large, too small, or mislocated and causes incorrect interpretation |
| Type of camera system not recorded on images | Study processed incorrectly, with incorrect data or results |
| Technologist initials missing from images | Data incorrectly calculated (wrong formula used) |
| Camera failure; patient moved to other system | Incorrect notations: directional, study, view, image labels, if they contribute to incorrect study interpretation |
| Restarting of camera or computer required | Furosemide or cholecystokinin not administered at correct time |
| Study modification not recorded (e.g., patient inability to comply) | Equipment failure; study cannot be performed for patient who has been dosed |
| Images acquired in wrong projection |
