Insights
Cardiac MRI phase images can show an aortic artifact mimicking dissection. This artifact is caused by helical blood flow and is discussed in this study.
Area of Science:
- Cardiovascular imaging
- Medical physics
Background:
- Cardiac-triggered thoracic spin-echo (TSE) sequences are crucial for cardiac imaging.
- Artifacts in MRI can lead to misdiagnosis, impacting patient care.
Observation:
- Phase images from cardiac-triggered thoracic spin-echo scans may exhibit an artifactual border-like feature across the aorta.
- This feature can be erroneously interpreted as aortic dissection.
Findings:
- The artifact originates from helical blood flow within the aorta.
- Understanding the cause and appearance of this artifact is essential for accurate interpretation.
Implications:
- Correct identification of this artifact prevents misdiagnosis of aortic dissection.
- Improved understanding aids radiologists in interpreting thoracic MRI scans accurately.
Abstract:
Phase images of cardiac-triggered thoracic spin-echo scans can present an artifactual border-like feature across the aorta. This may be misinterpreted as a dissection. The artifact results from helical flow in the aorta; cause and appearance of the artifact are discussed.
