Research Interests

The Laboratory of Imaging Technology Program, led by Dr. Adrienne Campbell-Washburn, focuses on the development of novel MRI technology for cardiac imaging, lung imaging, and MRI-guided cardiovascular catheterization procedures. The lab uses a custom high-performance 0.55T MRI system as well as clinical MRI systems. Specifically, Dr. Campbell-Washburn’s lab develops rapid non-Cartesian imaging methods, inline artifact corrections, and advanced image reconstruction methods which use contemporary computational power integrated into the clinical environment via the Gadgetron ( The lab emphasizes translation of new methods to clinical applications through collaboration with interventional cardiologists, imaging cardiologists, pulmonologists, radiologists and critical care physicians.

Measurement of regional lung function using oxygen-enhanced MRI.

3D stack-of-spirals ultrashort-TE imaging in a healthy volunteer during inhalation of room air versus 100% oxygen. Lung signal intensity histograms demonstrate signal enhancement on T1-weighted imaging with hyperoxia, which results in signal enhancement visible in percent enhancement maps.

Clinical Trials and Studies

Adultos, Ancianos
Se Aceptan Voluntaries Saludables
Desarrollo de nuevas técnicas de imagen por resonancia magnética cardiovascular. Este estudio compara la eficacia de dos tipos de escáneres de resonancia magnética (RM) para detectar diferentes tipos de cardiopatías, como la cardiopatía coronaria, la insuficiencia cardíaca, las cardiopatías congénitas y las valvulopatías cardíacas. El nuevo tipo de escáner de RM de este estudio usa menos energía que un escáner tradicional y puede ser adecuado para personas que tienen dispositivos metálicos en el cuerpo. Para participar en este estudio, debe ser sano o debe tener diagnóstico de cardiopatía coronaria estable y debe tener al menos 18 años. Este estudio se lleva a cabo en Bethesda (Maryland).

Adrienne Campbell-Washburn, Ph.D.

Senior Investigator​ ​

Dr. Adrienne Campbell-Washburn graduated with her B.Sc. in physics from the University of Western Ontario (Canada), and received her PhD in Medical Physics from University College London (UK). She joined NHLBI in 2013 as a postdoctoral fellow in the Laboratory of Cardiovascular Interventions. Dr. Campbell-Washburn was appointed Staff Scientist in 2016 and director of the MR Technology Program in 2017. As of 2020, Dr. Campbell-Washburn became an Earl Stadtman Investigator in NHLBI and the chief of the MRI Technology Program. Dr. Campbell-Washburn is a Junior Fellow of the International Society for Magnetic Resonance in Medicine, a member of the Society for Cardiovascular MRI, and member of the Magnetic Resonance in Medicine editorial board. Her lab has pioneered 0.55T MRI technology for imaging the heart and lungs.
