For the first time, digital radiography offers the ability to see the physiological movement of anatomic structures to evaluate function using special and temporal resolution. Dynamic Digital Radiology (DDR) is NOT Fluoroscopy, it is a new way to use a digital x-ray to capture and measure anatomical movement.

DDR is the only radiological exam that allows visualizing body function and motion on a large plane with a low dose. Most advanced medical imaging technologies like CT and MRI provide superb spatial resolution but not the movement. Ultrasound has a limited range and fluoroscopy does not provide enough resolution to evaluate soft tissue without contrast

DDR in Orthopedics

Orthopedic clinicians have shown significant interest in DDR as a tool for visualization of movement and diagnosis of abnormalities. Traditionally, Orthopedic specialists rely on multiple static images to assess body function, having the ability to capture the full dynamic cycle can provide additional information for a comprehensive assessment, before needing a CT or MRI.  DDR can help assess Biomechanics and Musculoskeletal injury, such as whiplash. Furthermore, DDR can acquire images in prone, supine and other weight-bearing positions to facilitate treatment follow-up or postoperative evaluation of movement (knee, wrist, spinal fusion, etc.). Dynamic Digital Radiology uses advanced image processing to capture sequential low-dose radiographs over time to observe the dynamic interaction of anatomical structures, such as soft tissue and bone. The digital nature of DDR makes it a promising platform for AI (Artificial Intelligence) applications.

DDR stands apart from other imaging modalities. Acquiring weight-bearing radiographs that show range of motion for up to 20 seconds, provide enhanced clinical capabilities. According to an article in Applied Radiology, DDR allows a more comprehensive and yet streamlined assessment by incorporating a visual and quantifiable evaluation of body function and mechanics than traditional radiography.
