Effective June 12, 2017, Progressive Radiology opened Progressive Radiology at Columbia, the facility previously known as Balum Imaging. This full service Radiology facility, offering 3T MRI, PET/CT, CT, Ultrasound, DEXA, and X-ray, is conveniently located on the Columbia Medical Campus at 5500 Knoll North Drive, Suite 190, Columbia, 21045. 3D Mammography, as well as breast biopsies, will be an added service this Fall.

Progressive Radiology has supported the Howard County community for the last 15 years, as the reading radiologists for Howard Open MRI and Howard Radiology but left the market in May 2016 when Howard Radiology sold to a large hospital system. Now, your preferred radiologists, Chad Silverberg, D.O., David Boyd, M.D., and Elizabeth Hartman, M.D., are back to provide the musculoskeletal, neurological and body sub-specialized, detailed reports that the community had come to trust. Neuroradiologist, Dr. Mark Monteferrante, one of the Progressive Radiology founders, will also be providing spine and brain reports and interventional procedures for the new site. Islamiat Ego-Osuala, M.D. recently joined the Progressive Radiology at Columbia team to support the Howard County medical community as well. Her sub-specialties include body and women’s imaging.

Progressive Radiology also provides X-ray services at First Call Urgent Care, located at 10981 Johns Hopkins Road, Laurel, MD 20723. Progressive Radiology patients may visit First Call Urgent Care for walk-in X-ray services between 8 a.m. to 8 p.m. Monday through Friday and 8:00 a.m. to 5:00 p.m. on Saturdays and Sundays.
