Dr. Gauri Karur is an Assistant Professor at the Department of Medical Imaging, University of Toronto, a Cardiothoracic radiologist at the Joint Department of Medical Imaging and a Clinician-Investigator at the University Health Network. Dr. Karur’s research interests include the use of new MRI techniques to further our understanding of cardiovascular health in genetic and acquired aortic and pulmonary arterial pathology.
Dr. Karur completed her undergraduate medical education and post-graduate training in Diagnostic Radiology from Kasturba Medical College, Manipal University, India. She pursued clinical fellowships in Adult Cardiothoracic Imaging and Pediatric Cardiac MRI at St. Michaels Hospital, University Health Network and The Hospital for Sick Children, University of Toronto.
Dr. Karur is passionate about medical trainee education and has won teaching awards at the University of Toronto. As an immigrant, person of colour, and a toddler’s mom, she is keenly aware of the challenges people face in the pursuit of their aspirations in medicine. She is particularly passionate about mentoring international students and medical graduates.
Outside of clinical work and academia, Dr. Karur enjoys spending time with her daughter, traveling, and exploring the food scene in different cities with her husband.
- Cardiac Magnetic Resonance Imaging T1 and T2 Mapping in Systemic Lupus Erythematosus in Relation to Antimalarial Treatment
CONCLUSIONS: The relationship between T1 and AM treatment duration differed between groups. Native T1 decreases with longer treatment in patients […]

Heritable Thoracic Aortic Disease (HTAD) is caused by mutation of a gene that confers a high risk for thoracic aortic aneurysms and dissections. […]
- Association of Pectus Excavatum With Ventricular Remodelling and Mitral Valve Abnormalities in Marfan Syndrome
Background: Marfan syndrome (MFS) is an inherited connective tissue disorder. Pectus excavatum (PEX) is common in MFS. The purpose was to evaluate […]
- Reversal of right ventricular pressure loading improves biventricular function independent of fibrosis in a rabbit model of pulmonary artery banding
Right ventricular (RV) pressure loading leads to RV and left ventricular (LV) dysfunction through RV hypertrophy, dilatation and fibrosis. Relief of […]

- Left Ventricular Mass and Wall Thickness Measurements Using Echocardiography and Cardiac MRI in Patients with Fabry Disease: Clinical Significance of Discrepant Findings
CONCLUSION: TTE overestimates LVM and MWT and has lower reproducibility compared with cardiac MRI in Fabry disease. Measurement discrepancies between […]
- The impact of pulmonary valve replacement on pregnancy outcomes in women with tetralogy of Fallot
CONCLUSIONS: Pregnancy outcomes did not differ according to PVR status in our cohort. While RV volumes remained unchanged in PVR+ women, interval RV […]
- Cardiac MRI assessment of the right ventricle pre-and post-kidney transplant
Worsening renal function in chronic kidney disease correlates with worsening right ventricular (RV) systolic function. We evaluated the association […]

CONCLUSIONS: Inclusion or exclusion of papillary muscles has a significant effect on LVM quantified by cardiac MRI, and therefore, a standardized […]
- Increased Spread of Native T1 Values Assessed With MRI as a Marker of Cardiac Involvement in Fabry Disease
OBJECTIVE. Cardiac involvement is the leading cause of mortality in Fabry disease. Noninvasive markers of cardiac involvement are needed to identify […]
- Augmentation of pulmonary blood flow and cardiac output by non-invasive external ventilation late after Fontan palliation
CONCLUSION: External ventilation acutely augments PBF and CO in adult Fontan subjects. Confirmation of these findings in larger populations with […]
