Dr. Tsekos’ research is focused on the development and application of magnetic resonance imaging (MRI) and spectroscopy (MRS) methodology. Primary emphasis is in cardiovascular and interventional MRI.

MRI offers excellent anatomical definition and a plethora of soft tissue contrast mechanisms for the assessment of the pathophysiology of tissue and as a means to guide and monitor the performance of image-guided biopsies, minimally invasive therapeutic procedures and computer-assisted surgeries. With MRI, it is possible to combine diagnostic and interventional methods in an integrated single-modality suite, which would not only diagnose disease but also would guide interventional procedures and assess the results of the intervention. Such capabilities could facilitate new therapeutic and surgical approaches and may result in improved management of patients.

Cardiovascular and interventional MRI is pursued using methodology and developments in the areas of MRI physics and pulse sequence development, development of MR-compatible robotics and interventional instrumentation, and image processing. Using these approaches, Dr. Tsekos is developing MR-guided coronary interventions, and robot-assisted minimally invasive procedures with real-time MR guidance.
