About Our Radiologists

primeimaging_doctors_2.jpg
 

PrimeImaging features ten of the top radiologists in the Chattanooga and North Georgia area. Like other medical specialists, radiologists complete four years of medical school, followed by at least four years in a residency program. Eight of our physicians went even further and worked in an additional fellowship program. All are board-certified.

Our radiologists have 10+ years of experience in at least one of these fields: vascular and interventional radiology, musculoskeletal imaging, nuclear medicine, positron emission tomography, diagnostic radiology and neuroradiology. 

Although each has their subspecialty, one clear goal connects our doctors: To precisely diagnose and combat diseases and injuries using our state-of-the-art medical imaging technologies.
