Meet Ronald Peshock, M.D.
Heart Imaging Specialist in Dallas

If you’re having heart trouble, seeing the problem with the best imaging technology and having your scans interpreted by highly specialized doctors makes a world of difference. That’s when you need Ronald Peshock, M.D., on your team.

Trained as a cardiologist with a special interest in cardiac imaging, Dr. Peshock uses magnetic resonance imaging (MRI) and computed tomography (CT) to help diagnose and treat cardiac diseases such as coronary artery disease, heart muscle disease or cardiomyopathy, cardiac valve disease, and congenital heart disease.

Patients typically get referred to Dr. Peshock by their cardiologist or primary care physician. He works with physicians at UT Southwestern and throughout the Dallas-Fort Worth area. Patients also come to see him from around the state to access his special expertise in heart imaging.

“At other institutions, patients may not meet with the doctor who reads their heart imaging study, but I try to have as much face-to-face contact as possible with my patients,” Dr. Peshock says.

“Although I specialize in imaging, my work as a cardiologist means I understand the impact that imaging of the heart has on decisions affecting a patient’s care. I think it’s important to be able to answer any questions they have about their condition or imaging test, both directly and in collaboration with their referring doctor.”

Developing New Techniques

While Dr. Peshock’s overall expertise is in heart imaging, he has a particular interest in cardiac MRI, focusing most of his clinical and research efforts in this area. 

Dr. Peshock and his UT Southwestern colleagues have been instrumental in the development and application of new techniques including cardiac MRI, to provide moving pictures of a beating heart which can measure heart function and blood flow, and then link this information to diseases and issues elsewhere in the body.

“It’s been a highlight of my career to play a role in the development of new techniques that actually benefit patients,” he says. “Many physicians and researchers never get to see their innovation used in a clinical setting, so I’m proud of that.”
