Who We Are

California Advanced Imaging Medical Associates

California Advanced Imaging Medical Associates (CAIMA) has grown from a 5 person practice in the 1980s to the largest private radiology group in San Francisco and the West Bay region. We exclusively provide the radiology services at 11 hospitals from Sonoma Valley Hospital in the north to Sequoia Hospital in the south. Our 68 radiologists are organized into regional divisions, leading to the ability to provide locally oriented services combined with the business and information technology support of CAIMA.

Our mission is to provide subspecialty expertise in all areas of imaging to our hospitals and outpatient imaging centers. By concentrating on subspecialty expertise we are more than readers of imaging studies, but instead serve as valuable consultants to both our referring physicians and patients we serve. We continue our academic approach to our profession by actively participating in multidisciplinary conferences at our affiliated hospitals and imaging centers, teaching at major medical schools, and frequently giving national and international lectures in our fields as well as publishing in the medical literature.

CAIMA is centrally managed by a Board of Directors with representatives of all divisions and an executive committee of core leadership radiologists who, along with our experienced administrative staff, manage the day to day affairs of our practice.

We have a wholly owned management company, IMMIX LLC., which provides all billing, insurance, management and other business functions for the radiologists, allowing them to concentrate completely on their clinical practice of radiology and keeping all of our divisions at the forefront of current radiology practice guidelines. IMMIX also allows us to be more than contract physicians, but in addition business partners with our affiliated hospitals. We jointly own and cost effectively manage a prominent imaging centers in San Francisco along with our affiliated hospitals. In addition, we independently own and manage California Advanced Imaging in Atherton, California. We also jointly own and provide subspecialty expertise to New Century Imaging in Oradell, New Jersey.

CAIMA has long been a pioneer in the development and implementation of teleradiology, allowing us to share our expertise throughout the United States in addition to our Bay Area practice. The radiologists in our National Orthopedic Imaging Associates and National Specialty Imaging Associates teleradiology groups provide readings and consultations at more than 40 imaging facilities in 13 states. We provide both on site staffing and teleradiology back up for the Nebraska Orthopedic Hospital in Omaha, Nebraska.

While proud that we have achieved this level of growth and strength we are most proud that we have accomplished this while continuing to provide local, personalized and focused service to our individual patients and referring physicians at each of our division’s hospitals and outpatient centers.
