As a radiologist at Cancer Treatment Centers of America® (CTCA) in Tulsa, Dr. Timothy McCay plays a critical role in our patients’ care. He performs minimally invasive procedures using some of the most sophisticated, medical imaging tools and software available. These intricate procedures help our oncologists diagnose and treat our patients.

Dr. McCay received an osteopathic medical degree from the College of Osteopathic Medicine at Oklahoma State University. Prior to that, he completed two undergraduate degrees—one in nuclear medicine at the University of Oklahoma Health Sciences Center and the other in chemistry. While working on a second bachelor’s of science degree, Dr. McCay conducted research on nuclear medicine cardiovascular imaging.

Dr. McCay completed a residency in radiology at Oklahoma State University Medical Center (formerly known as Tulsa Regional Medical Center), where he also served as Chief Intern.

Before joining our staff of compassionate cancer experts, Dr. McCay helped establish a teleradiology practice at Oklahoma State University Medical Center. This allowed diagnostic images to be electronically transmitted among 14 Oklahoma hospitals. Dr. McCay also gained significant experience as a nuclear medicine technologist at Presbyterian Hospital of Dallas. In addition, he worked as a chemist and director of two district labs for Halliburton, and spent two years working in respiratory therapy.

Dr. McCay is a member of a number of professional associations, including the American College of Radiology and the Society of Nuclear Medicine, as well as the American and Oklahoma Osteopathic Associations.

In his spare time, he enjoys breeding and showing horses, and spending time with his family.

Patient ratings and comments

Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
