Free Content 3D Cinematic Volume-Rendering Technique of Traumatic Spine Injuries: A Powerful Tool for Radiology Education

Spine trauma represents a common indication for imaging in the emergency department. Multidetector CT imaging, with its advantage of multiplanar reconstructions and fast image acquisition, is the technique of choice in the initial assessment of a patient with polytrauma. While many simple spinal fractures are adequately evaluated on 2D multiplanar reconstruction images, more complex, potentially displaced fracture patterns can be more fully highlighted on 3D reconstructions. Compared with conventional volume-rendering techniques, cinematic rendering uses a complex illumination model to create a more photorealistic representation of the fracture patterns, images that are certain to excite both trainees and clinicians. This review demonstrates the educational value and clinical utility of 3D cinematic rendering images in understanding complex spinal column injuries.

Learning Objective: To demonstrate the methodology, clinical applicability, and educational utility behind 3D photorealistic cinematic rendering images of spine injuries, with emphasis on the “tension bands” biomechanical concept

Keywords: CR = cinematic rendering; DISH = diffuse idiopathic skeletal hyperostosis; ED = emergency department; VRT = volume-rendering technique

  • Neurographics is the peer-reviewed, quarterly educational journal of the American Society of Neuroradiology. The journal includes review articles as well as high-yield case reports that have been solicited from society meetings, including the annual meeting of the ASNR as well as the American Society of Spine Radiology, the American Society of Pediatric Neuroradiology, the American Society of Functional Neuroradiology, and the American Society of Head and Neck Radiology meetings. Unsolicited educational review articles and case reports are also accepted for review at the discretion of the Editor-in-Chief. Submissions focusing on a pictorial approach to educational objectives are highly encouraged. The journal is open access and available online. CME credit is offered for reading review articles and completing activity evaluations through the ASNR Education Connection website:
