Deep Learning Pearls
- Cinematic rendering is a 3D reconstruction technique inspired by the animated movie industry. It follows the same steps used for volume rendering in determining colour and opacity that models real-life physical propagation of light providing photorealistic 3D images with more surface details. The application of cinematic rendering in clinical practice has been described for pre-operative planning of tumours such as GIST. Originally clinical use of 3D imaging was confined to calculating organ volumes or orthopedic applications; however, the use of helical technology for the propagation of thin slice computed tomography (CT) in conjunction with advanced image reconstruction software has allowed this to be utilized for a variety of other applications. Applications for cinematic rendering have been reported to include lesion characterization, localization, and risk stratification in the pre-operative setting.
Utilization of Cinematic Rendering for Evaluation of Gastrointestinal Stromal Tumours (GIST)

Canadian Association of Radiologists Journal (in press) - “Cinematic rendering of GIST helps demonstrate the submucosal origin of the mass and visualize the dynamic enhancement pattern within the tumour allowing for better anatomical evaluation of the lesion providing more information on areas of necrosis and enhancement. Additionally, there is increased information regarding the growth pattern, vascular supply, adjacent anatomic structures, and blood vessels which improves pre-operative planning. Active bleeding from a small bowel tumour is difficult to characterize on conventional CT. Cinematic rendering can more easily detect if there is bleeding from a small bowel tumour. It also provides increased information to differentiate GIST form other gastrointestinal tumours, especially at the ampulla and in the pelvis where anatomical detail is limited on conventional CT.”

Canadian Association of Radiologists Journal (in press) - “Cinematic rendering is an exciting new technique currently in its infancy that has the potential to add great value to our practice. To fulfill the advice of Dr Brady: to move forward and keep up, the next step should be to investigate how to implement cinematic rendering into our day-to-day practice.”
