Radiology: Medical Imaging for Diagnosis and Treatment

District Medical Group (DMG) radiologists are specially trained in a wide array of medical specialty imaging and treatments to support patients of all ages at Valleywise locations across Maricopa County. In addition, we have pediatric radiologists at DMG Children’s Rehabilitative Services (DMG CRS), the largest multi-specialty interdisciplinary clinic (MSIC) in Arizona. At all facilities, you can be assured the highest level of technology and resources are utilized to provide reliable and valuable radiology services.
