The vertex scan: an important component of cranial computed tomography
AJR. American Journal of Roentgenology
|April 1, 1978
Summary
Omitting vertex scans in cranial computed tomography (CT) can miss significant abnormalities in 3% of patients. Ensuring complete CT scans, including vertex views, is crucial for accurate diagnosis and patient care.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Physicians sometimes omit superior brain and calvarium scans in cranial computed tomography (CT) due to time constraints.
- Standardized CT reporting and manufacturer training may suggest incomplete scan series are acceptable.
- Excluding vertex scans can lead to overlooking 10%-15% of the brain's total volume.
Purpose of the Study:
- To evaluate the diagnostic impact of omitting vertex scans in cranial CT.
- To determine the frequency and types of pathologies missed by incomplete CT examinations.
Main Methods:
- Review of 2,000 consecutive cranial CT studies.
- Analysis of abnormalities found exclusively on vertex scan pairs.
Main Results:
- Vertex scans revealed significant or sole abnormalities in 3% of the reviewed cases.
- Pathologies missed by omitting vertex scans varied in type and clinical importance.
Conclusions:
- Vertex scans are essential for a complete cranial CT examination.
- Routine inclusion of vertex scan levels is recommended to avoid missing critical pathologies.
