Summary
Mislabeled coronal computed tomography (CT) scans can lead to wrong-sided surgery. Reviewing scan markings can help identify errors, emphasizing the need for awareness and discussion to prevent patient harm.
Area of Science:
- Radiology
- Medical Imaging
- Patient Safety
Background:
- Coronal computed tomography (CT) scans require careful orientation to distinguish right from left.
- Errors in labeling CT scans can occur due to reliance on technician input and anatomical symmetry.
Observation:
- Two cases of mirror-image reversal in coronal CT scans were reviewed.
- One case led to wrong-sided surgery and a subsequent lawsuit.
Findings:
- Radiologists may overlook mislabeled scans due to anatomical symmetry.
- Reviewing scan markings is crucial for otolaryngologists to detect labeling errors.
Implications:
- The incidence of mislabeled CT scans is unknown but poses a risk for patient care.
- Increased awareness and open discussion are vital for preventing wrong-sided surgeries and medical errors.
