Cardiothoracic Radiology
Academic Leadership and Innovation in Cardiothoracic Imaging
We actively lead and contribute to pioneering studies that enhance imaging of the heart, lungs, mediastinum and thoracic vasculature — driving improvements in diagnostic accuracy, workflow efficiency and patient outcomes.
Our research focuses on emerging technologies such as low-dose CT protocols, advanced cardiac MRI techniques, AI-assisted image analysis, and quantitative imaging biomarkers for lung disease and cardiovascular conditions. These innovations help shape the future of cardiothoracic imaging and expand its role in preventive and precision medicine.
As passionate educators, our board-certified, fellowship-trained radiologists provide rigorous training and mentorship to medical students, residents and fellows. Our Cardiothoracic Imaging Fellowship offers immersive clinical experience, scholarly engagement and exposure to high-volume, complex cases. Through hands-on learning and interdisciplinary collaboration, we prepare the next generation of cardiothoracic radiologists to lead with expertise, innovation and compassion.
Advanced Imaging Capabilities in Cardiothoracic Radiology
Use of specialized instrumentation enables high-resolution imaging of the heart, lungs and thoracic structures, supporting precise evaluation of complex cardiothoracic conditions.
- Ultra-high-resolution imaging with lower radiation and reduced noise
- Enhanced visualization of fine pulmonary structures, coronary arteries and subtle vascular abnormalities
- Enables earlier detection and more confident diagnosis in cardiothoracic care
- High-resolution chest CT for detailed evaluation of lung parenchyma, airways and interstitial lung disease
- Coronary CT angiography for non-invasive assessment of coronary artery disease and plaque characterization
- Dual-energy CT for enhanced tissue characterization and iodine mapping
- Cardiac MRI with cine imaging, late gadolinium enhancement, T1/T2 mapping and myocardial strain analysis
- Vascular MRI for non-invasive assessment of the thoracic aorta and pulmonary arteries
- Congenital heart disease imaging with high-resolution anatomical and functional protocols
- Quantitative techniques including flow quantification and parametric mapping for precision diagnostics
Residents, fellows and medical students benefit from:
- Fellowship-trained radiologists who prepare the next generation to offer unparalleled diagnostic accuracy
- Seamless integration with multidisciplinary teams, ensuring comprehensive training
- Preparation to shape the future of radiology through research, education and national leadership roles
