Perceptual omission errors occur in 1.2% of oncologic PET/CT scans, most commonly involving bone metastases and colon uptake. Identifying these errors improves diagnostic accuracy in PET/CT interpretation.
Area of Science:
- Radiology
- Nuclear Medicine
- Oncologic Imaging
Background:
- Omission errors in medical imaging can lead to missed diagnoses and patient harm.
- While studied in conventional imaging, data on perceptual omission errors in functional imaging, specifically PET/CT, is lacking.
Purpose of the Study:
- To evaluate the frequency and characteristics of perceptual omission errors in the PET component of oncologic PET/CT.
- To analyze hazardous scenarios contributing to these modality-specific errors.
Main Methods:
- Collection of perceptual omission errors from routine PET/CT reporting over 26 months at a tertiary center.
- Detection of omissions through follow-up studies and multidisciplinary meetings.
Main Results:
- Significant omission errors were identified in 1.2% of 2100 PET/CT reports.
- The most frequent omissions involved bone metastases and focal colon uptake.
- Six PET-specific causative factors were identified, with proposed solutions.
Conclusions:
- Findings aim to increase awareness among interpreting physicians regarding high-risk areas in PET/CT.
- Implementation of targeted reading strategies can enhance the accuracy of PET/CT interpretation.
