ONS has been awarded full accreditation for its MRI scanner as a result of a recent survey by the American College of Radiology (ACR). The ACR awards accreditation to facilities for the achievement of high practice standards. A peer-review panel assesses the qualifications of practice personnel and the adequacy of the facility equipment and reports their findings to the ACR’s Committee on Accreditation. An evaluation of the ONS Magnetom Espree Open Bore MRI was conducted by a survey panel of board-certified physicians and medical physicists who are experts in the field.

The ONS open MRI has an opening of more than 27 inches in diameter and has four times more power than standard open MRIs.

For virtually all exams, including lumbar spine scans, the patient’s feet enter the scanner first and the head remains outside of the magnet bore. A Board-certified radiologist evaluates each patient’s MRI scan and completes a diagnostic report for the physician. Through a digital computer network, doctors are able to review images and reports with their patients in the exam room.

The ACR, headquartered in Reston, VA, is a national organization serving more than 32,000 diagnostic and interventional radiologists, radiation oncologists, and nuclear medicine and medical physicists with programs focusing on the practice of medical imaging and radiation oncology and the delivery of comprehensive health care services.
