The Cardiovascular Imaging (CVI) Division uses the latest magnetic resonance and computed tomography technology for the noninvasive imaging of the heart and vascular system in children and adults. Sophisticated post-processing techniques provide unprecedented 3- and 4-dimensional visualization of complex cardiovascular anatomy and pathology to facilitate treatment planning for surgical or endovascular procedures, some of which are pioneered at and unique to Stanford. The CVI Division provides a fellowship training program for cardiovascular radiologists and participates in educational curricula of trainees in radiology, cardiology, cardiothoracic and vascular surgery. Clinical research topics include the imaging of the aorta, heart valves, and blood flow. Research in pediatric cardiovascular imaging includes radiation dose reduction strategies in pediatric cardiac CT as well as new MRI and CT techniques applied to the clinical management of congenital heart disease.
