“…Cinematic rendering produces photo-realistic images and was found to provide greater depth perception and spatial impression in comparison to volume rendering, however at the cost of requiring significantly greater computing power. 123 A study further explored the use of cinematic rendering for cardiac intraluminal visualization through a modified preset called Black Blood Cinematic Rendering, clearly identifying factors such as thrombosis and medical devices such as stents, when compared with conventional imaging. 124 …”

Abstract3D printing as a means of fabrication has seen increasing applications in medicine in the last decade, becoming invaluable for cardiovascular applications. This rapidly developing technology has had a significant impact on cardiovascular research, its clinical translation and education. It has expanded our understanding of the cardiovascular system resulting in better devices, tools and consequently improved patient outcomes. This review discusses the latest developments and future directions of generating medical replicas (‘phantoms’) for use in the cardiovascular field, detailing the end-to-end process from medical imaging to capture structures of interest, to production and use of 3D printed models. We provide comparisons of available imaging modalities and overview of segmentation and post-processing techniques to process images for printing, detailed exploration of latest 3D printing methods and materials, and a comprehensive, up-to-date review of milestone applications and their impact within the cardiovascular domain across research, clinical use and education. We then provide an in-depth exploration of future technologies and innovations around these methods, capturing opportunities and emerging directions across increasingly realistic representations, bioprinting and tissue engineering, and complementary virtual and mixed reality solutions. The next generation of 3D printing techniques allow patient-specific models that are increasingly realistic, replicating properties, anatomy and function.

“…The 3D visualization and textural contrast provided by CR can improve visualization of complex vascular anatomy, as shown in the above cases, which is essential for preoperative evaluation. One small study assessing the value of CR for extracardiac anatomy in patients with congenital heart defects indicated that pediatric cardiac surgeons preferred the CR images to VR images due to improved “spatial impression in general” and “depth perception” [26] .…”

“…Evaluation of CR in the pediatric population has not been as well-assessed. While there has been one study demonstrating the potential benefit of CR in patients with complex congenital heart defects [26] , and a case series utilizing CR in adolescent and young adult patients with Kawasaki’s disease-associated coronary artery aneurysms [27] , the extent to which CR may have applicability in the pediatric population is unknown.…”

“…A number of prior publications have suggested potential advantages in terms of superior image quality of CR in different clinical settings in comparison to conventional 2D imaging and traditional 3D rendering methods (Johnson et al, 2017; Binder, et al, 2018; Chu et al, 2018; Rowe and Fishman, 2018; Rowe et al, 2018a, b, c; Röschl et al, 2019). Additionally, CR has already been applied for medical education in the past (Fellner et al, 2017).…”

Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR-CT sequence (−204.21 ± 156.0 seconds) and the CT-CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education. Anat Sci Educ 14: 22-31.
