About Mark Baker, MD

Mark Baker, MD, was recruited by Cleveland Clinic in 1994 to head the Abdominal Section, covering CT, GI and GU Radiology, Ultrasound and MRI. In 2002, he stepped down from leadership in the section to allow a younger staff member to grow in leadership experience.

His expertise is primarily in gastrointestinal diseases and his current research interests are in the evaluation of small bowel diseases with CT and MR enterography. He provides radiological services in CT, MRI, Gastrointestinal Fluoroscopy and in Abdominal Interventions.

Dr. Baker was born and raised in California, graduated from Occidental College and migrated east for medical school in Chicago, at Loyola-Stritch School of Medicine, then he completed two years of internal medicine training and a diagnostic radiology residency. He moved to Duke University for a computed tomography and ultrasound fellowship and became a clinical fellow of the American Cancer Society. He joined the staff at Duke University as an assistant professor of radiology in 1984. In 1989, he was promoted to associate professor of radiology, and in 1992, he became Head of the Section of Abdominal Imaging in the Duke Radiology Department, covering CT and GI radiology.

Dr. Baker is author and co-author of more than 100 peer-reviewed papers in the area of abdominal imaging. He is most known for his work in Computed Tomography and was named a fellow of the Society of Computed Body Tomography and Magnetic Resonance in 2002. He started the CT colonography program at Cleveland Clinic in 2000 and the CT enterography program in 2005.

Industry Relationships

Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

As of 8/4/2022, Dr. Baker has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities. Click here to view a listing of instances where Cleveland Clinic has identified a Public Health Service (PHS)-Reportable Financial Conflict of Interest and has put measures in place to ensure that, to the extent possible, the design, conduct and reporting of the research is free from bias.
