Welcome to the Dental Radiology Diagnostics website, where we provide a dental imaging interpretation service that helps dentists provide the highest quality care for their patients.

All of our oral and maxillofacial radiologists are board certified by the American Board of Oral and Maxillofacial Radiology (ABOMR) as well as university faculty members.

Each dental imaging report (sample report) allows the referring provider to practice with the confidence and security of knowing that disease or abnormalities have been identified or excluded. Cone Beam CT volume examinations can be uploaded to our secure, HIPAA-compliant website with the click of a mouse. If your practice has web access, you have all that is required to fully utilize our services. We accept DICOM files through our secure website and provide our corresponding report through the same portal.

The Image Gently Alliance

Dental Radiology Diagnostics Proudly Supports Alliance for Radiation Safety in Pediatric Imaging

The Alliance for Radiation Safety in Pediatric Imaging - the Image Gently Alliance - is a coalition of health care organizations dedicated to providing safe, high quality pediatric imaging worldwide. The primary objective of the Alliance is to raise awareness in the imaging community of the need to adjust radiation dose when imaging children. The ultimate goal of the Alliance is to change practice.

The Alliance chose to focus first on computed tomography (CT) scans. The dramatic increase in the number of pediatric CT scans performed in the United States in the past seven years and the rapid evolution, change, and availability of CT technology and equipment well justify this Alliance strategy. The campaign has grown to include: parent information, Fluoroscopy, Interventional Radiology, Nuclear Medicine, and Digital Radiography.
