Artifacts and pitfalls of high-resolution CT scans
Critical Reviews in Diagnostic Imaging
|January 1, 1985
Summary
Computed tomography (CT) artifacts can mimic pathologies in head and spine scans. This review highlights common CT artifacts and their causes to help radiologists avoid misinterpreting these imaging pitfalls.
Area of Science:
- Medical Imaging
- Radiology
- Image Analysis
Background:
- Computed tomography (CT) artifacts have been recognized since the inception of CT technology.
- Technological advancements and improved algorithms have resolved some artifacts, but others persist in high-resolution scans.
Purpose of the Study:
- To summarize the causes of common CT artifacts.
- To present artifacts that mimic pathological conditions in clinical head and spine imaging.
- To alert radiologists to potential misinterpretations caused by imaging artifacts.
Main Methods:
- Review of reported investigations on CT artifacts.
- Analysis of artifact characteristics and their resemblance to pathological patterns.
- Clinical case examples of artifacts in head and spine CT scans.
Main Results:
- CT artifacts, while reduced by technological progress, remain a challenge in modern imaging.
- Certain artifacts present visual similarities to known pathological conditions.
- Examples of artifacts mimicking pathology in head and spine imaging are identified.
Conclusions:
- Radiologists must be aware of persistent CT artifacts that can be mistaken for disease.
- Understanding artifact origins is crucial for accurate diagnosis in CT scans.
- This review aims to prevent misdiagnosis by highlighting artifactual findings in head and spine imaging.
