My focus is to anticipate and meet the needs of all patients, and to go the extra mile to provide the finest patient-centered, professional service. In order to achieve this service excellence, I have committed myself to monitoring details in the quality of care at every step in the imaging process, reviewing every case in detail and adding value with my subspecialty expertise, and always striving to achieve quality improvement in our practice. As a reflection on my personality, my desire to constantly learn in every aspect of my personal life also manifests itself in my commitments at the professional level. At the end of the day, my philosophy could be summarized by saying that I want to treat everyone as I would treat my own family.
Dr. Diaz is a pediatric radiologist with subspecialty training in pediatric cardiac imaging. Over the course of his training and during his time as a practicing clinical radiologist, he has interpreted tens of thousands of pediatric imaging exams. He has also overseen several thousand pediatric, congenital heart, computed tomography, and magnetic resonance imaging exams in patients of varying ages covering a broad spectrum of congenital heart disease. Dr. Diaz has been invited multiple times to lecture at national conferences with topics focused on advanced radiological imaging of the heart. During his time as a clinician, he has also served as a professor, clinical consult, and supervisor providing education to residents, clinical staff, and technologists on congenital heart imaging and various other pediatric imaging exams.
Dr. Diaz has a strong academic focus in doing research involving medical imaging processes and systems, particularly in technical aspects of imaging such as protocols, standardization, sequences, acquisition techniques, machine learning, and more. He is always working to translate this research into improved diagnostics for pediatric and cardiac imaging applications.
