Christopher R. Kagay, M.D. Memoriam

Christopher R. Kagay, M.D.
1972 – 2023

It is with great sadness that the physicians of California Advanced Imaging Medical Associates (CAIMA) announce the recent passing of Dr. Christopher R. Kagay on January 2, 2023, after a brief, unexpected illness.

Dr. Kagay completed his undergraduate education at Harvard University, earning a bachelor’s degree in Social Studies. Post baccalaureate, he attended Stanford University for his pre-medical education. He attended the University of California, San Francisco School of Medicine in 2004. Dr. Kagay joined CAIMA in July of 2010 after completing both his Radiology Residency and Fellowship at Massachusetts General Hospital / Harvard Medical School.

Upon joining CAIMA, Dr. Kagay quickly became Chair of the Diagnostic Imaging Departments at California Pacific Medical Center (CPMC). In 2021, Dr. Kagay was elected to serve as President of CAIMA where his responsibilities focused on leading the 65-member radiology group with divisions that include a nationally distinguished orthopedic teleradiology practice and numerous hospital-based divisions serving the major medical centers throughout the bay area with service locations in San Francisco, San Mateo, Marin, Sonoma and Lake counties.

Dr. Kagay’s impact on everyone he encountered was profound. He consistently presented the characteristics of an exemplary physician. As a colleague, it was universally accepted that Dr. Kagay was “talented, bright, hardworking, and an effective leader.” He had so many skills, and his expertise in the practice of radiology was widely recognized by both his radiology partners and by the by the multitude of distinguished attending physicians at CPMC. These leadership and clinical traits were summarized by the following comment from one of the CPMC sections chiefs:

“What a wonderful man… Chris was a ‘hub’ at CPMC, interacting with every specialty, and he was uniformly kind, responsive, thoughtful, and skilled……”

Most importantly, we remember Dr. Kagay as a compassionate, thoughtful, and caring individual who was fun to work with, extremely well liked and respected by everyone who came into contact with him, both inside and outside of the hospital.

Dr. Kagay leaves behind his wife and two children, family, and many friends. He will be greatly missed.

A GoFundMe page has been setup in Dr. Kagay’s name:

What’s the Difference Between a Breast MRI and a Mammogram?

No woman looks forward to getting a mammogram. The squeezing and pushing is certainly no fun, but it is the best screening tool to detect breast cancer.  However, there are many other examinations such as a breast MRI that can be used by California Advanced Imaging Medical Associates to diagnose cases of abnormal breast tissue.
