Summary
Magnetic resonance imaging (MRI) enhances computational fluid dynamics (CFD) simulations for Type B aortic dissection (TBAD) risk assessment. This review highlights MRI
Area of Science:
- Cardiovascular Imaging
- Biomedical Engineering
- Medical Physics
Background:
- Type B aortic dissection (TBAD) requires improved risk assessment tools for optimal patient treatment.
- Computational fluid dynamics (CFD) simulations can personalize risk assessment by quantifying hemodynamic parameters.
- Magnetic resonance imaging (MRI) offers a non-invasive method to acquire patient-specific data for CFD models.
Approach:
- A systematic review following PRISMA guidelines was conducted.
- Searches in Medline, Embase, and Scopus identified 136 articles.
- Twenty articles using MRI to inform CFD simulations for TBAD were included.
Key Points:
- Phase contrast MRI (PC-MRI) was the most common technique (19 studies) for providing CFD boundary conditions.
- CFD hemodynamic results were validated against PC-MRI in 12 studies.
- MR angiography and PC/cine MRI were used for geometric modeling and motion analysis.
Conclusions:
- MRI provides crucial structural, dynamic, and flow data for personalized CFD simulations in TBAD.
- Integrating MRI-derived data into CFD can aid pre-treatment planning and clinical decision-making.
- Further validation and larger studies are needed to fully realize MRI's potential in TBAD surgical planning.

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
