Background

Dr. Michael Schar an Associate Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science. His research focuses on technical development to improve cardiovascular MRI and to better understand cardiovascular diseases. 

Dr. Schär studied physics and then obtained a Ph.D. at the Swiss Federal Institute of Technology ETH on cardiovascular MR imaging and spectroscopy at 3 Tesla in 2005. Afterward, he joined Philips Healthcare as a clinical scientist where he first worked on-site at JHU and then was relocated to Phoenix, AZ. In August 2014, he joined the faculty at JHU.

Research & Publications

Research Summary

My research interests focus on the development of novel MRI and MRS techniques to study cardiovascular disease in patients. These include the development of MRI methods to non-invasively quantify coronary endothelial function that previously could only be measured by invasive cardiac catheterization. Endothelial dysfunction is a marker for sub-clinical disease, an independent predictor of adverse cardiac events, and a potential target for medical interventions when disease progression is still reversible; and the development of MRI/MRS methods to non-invasively quantify energy metabolism in the human heart and exercising leg to better understand disease mechanisms in people suffering from heart failure, fatigue, and HIV.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
