Associate Professor

Parkinson ,Applied Health Sciences

Steven Shea
  • Dr. Shea received his BBE (Biomedical Engineering) from The Catholic University of America in 1998. He then received his PhD (Biomedical Engineering) from Northwestern University and did his dissertation on using Magnetic Resonance Imaging (MRI) to detect ischemia in the heart. Dr. Shea went on to work at Siemens Medical Solutions as a research scientist, collaborating with institutions such as Johns Hopkins University, University of Maryland Medical Center, the NIH, Hopitaux Universitaires de Genève and the University of Utah. In 2013, he joined the Radiology Department at Loyola University Medical Center as an assistant professor and an MR Scientist. Clinically, Dr. Shea is responsible for optimizing MRI based imaging protocols, spearheading MRI safety guidelines, developing an ongoing process for quality assurance, and conducting MR equipment acceptance testing and annual reviews. Academically, he is providing MR physics education for medical students, residents, and fellows, as well as ensuring that appropriate staff receive training on MRI safety. His research interests involve the development of new MR image acquisitions, primarily for cancer imaging.

    What prompted you to pursue your field?

    I always had a strong interest in science, technology, and medicine from when I was an undergraduate. I was a biomedical engineering major and briefly considered applying to medical school as I was finishing my undergraduate degree. I then decided to pursue a PhD and somewhat lucked into finding an advisor who was researching new MRI methods to image the heart. I then really fell in love with the way that MRI could significantly impact patient care noninvasively and how quickly new imaging methods were developed to treat novel problems.

    What's it like to teach at Parkinson?

    I have really enjoyed the multi=disciplinary nature of the school where a large variety of fields of study are combined together to improve medicine and public health. All of the faculty I have interacted with are very collaborative and look to help each other achieve teaching and research goals.

    What does your department's focus mean to you?

    In general, medical physics draws heavily from the fields physics/engineering and medicine and allows you to make a direct impact on patient care using that physics/engineering knowledge. Challenges and new problems constantly surface which means you are never bored -- there is always something to improve, optimize, or fix.

    Why is this area of study important at this point in time?

    Medical imaging is growing more and more complex every year, especially with the rise of artificial intelligence. In addition, quality and safety are taking on more important roles within the healthcare systems, especially for reimbursement. Physicians and hospital staff often do not have the technical background to address these challenges, whereas medical physicist do. They are key contributors to assessing new technology, optimizing existing equipment, and setting up programs to ensure high image quality and patient safety around the imaging systems.

    What would you tell a student about why your field is exciting/important/the potential impact s/he could make?

    Medical imaging has become a crucial tool to diagnosing and treating patients. Almost any significant disease process requires imaging as it enables physicians to noninvasively look into the body. This is extremely powerful for diagnosing disease, tracking it, directing treatment, and then monitoring treatment efficacy. Medical physicists ensure that medical imaging is done with high quality so that patients receive accurate diagnoses and effective treatments.

    What "called" you to/attracted you to Loyola?

    Before coming to Loyola, I worked for an imaging vendor as a research scientist. I decided I wanted to get back into academics to pursue my own research ideas, to impart some of my knowledge to students, and to stay involved in clinical problems. Loyola was a great fit for all of those pursuits. Loyola is also in one of the greatest cities in the USA, which definitely was an added bonus.
