About Our Radiologists
PrimeImaging features 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. Most 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.
Joseph Busch, M.D.
Dr. Joseph Busch co-founded PrimeImaging, then Diagnostic Radiology Consultants, P.A., in 1992 to carry out his dream of the running a first-rate radiology practice in the Chattanooga and North Georgia areas. Born in Louisiana but raised in Tennessee, Dr. Busch completed his undergraduate at UT Knoxville and his medical doctorate and residency in Diagnostic Radiology at UT, Memphis.
Dr. Busch served his country as a general medical officer in the USPHS at the Merchant Marine facilities for two years during the Vietnam War. Following this, he served in the Tennessee National Guard M.A.S.H. unit for an additional two years.
Today, in addition to running his practice, Dr. Busch enjoys traveling as part of the International Prostate MRI Working Group. One of his public speaking highlights was as the keynote speaker at the Stanford University Molecular Symposium in 2009.
Dr. Busch has also written for renowned radiology publications and serves various professional organizations and associations, including as the past president of Chattanooga Regional Oncology Association and as the clinical advisor for A.P.S. Alliance and Sunhealth Alliance Imaging Advisory Committee.
James Busch, M.D.
Following in his father’s footsteps, Dr. James Busch developed a passion for the medical field early on. He earned his undergraduate degree from Millsaps College in Jackson, Mississippi and his medical degree at UT Memphis where he was inducted into the honor medical society, Alpha Omega Alpha. He then completed his Diagnostic Radiology residency and fellowships at the world-renowned Harvard Medical School.
Dr Busch’s passion in radiology is providing state-of -the-art patient care with the best technology. One area of Dr Busch’s special training includes radiology informatics where he led the initiative for Diagnostic Radiology Consultants (DRC) to be the first in the world to implement a comprehensive radiology interpretation software suite soon after moving to Chattanooga in 2004. With his love of soccer, he also gravitated towards specialized musculoskeletal training. He continues to enjoy providing that skill set to Prime Imaging and the sports medicine community of greater Chattanooga. His fellowship in Vascular and Interventional radiology also continues to drive his desire to help patients with cancer by providing minimally invasive options to treat or diagnose. Dr Busch was one of the pioneers of thermal ablation used to treat and cure cancers in patients who are not eligible for traditional surgical options.
Scott Kemmerer, M.D.
Scott Kemmerer, MD, is originally from Richmond, Virginia. He discovered the Chattanooga area while attending Southern Adventist University for his undergraduate degree in Biology.
