“…CR effectively displays the relationship between GIST and the surrounding structures, and can assist in operative planning. 37 Considering the improved image detail of CR and favorable observer perceptions, the technique is gaining wide acceptance in many institutions. The next step should be to investigate how CR can be implemented in the real-life setting and how it can positively influence patient care and outcome.…”

“…Third, contrary to other 3D techniques such as surface-shaded display, volume rendering, or maximum intensity projection, which are automated, 39 a radiologist with a special skill is needed and CR represents local extra work that raises important issues such as adequate staffing, outsourcing, and reimbursement. 37,40 Future Developments CR offers the potential for comprehensive assessment of GISTs. CR can potentially improve the appreciation of the spatial relationship between the GIST and surrounding organs and delineation of the major vascular supply, which may influence endoscopic or surgical planning.…”

“…CR can also potentially improve appreciation of the spatial relationship between a GIST and the adjacent structures. 4,37 This enhancement in the surgeon’s understanding of spatial relationships is a major advantage of CR by comparison with axial and multiplanar images (Figure 7). In addition, this may improve the diagnostic confidence with which the gastrointestinal tract can be ascertained as the organ of origin of the GIST.…”

“…Potentially superior 3D visualization of the intimate relationship of large infiltrating GISTs with compressed surrounding structures, is also an undisputed advantage of CR. 4,37 CR vascular mapping can also potentially improve visualization of the vascular supply of GIST, which is of importance to anticipate possible bleeding or unusual distribution of vessels before surgery. This is especially true for large GISTs that become exophytic with a complex vascularization.…”

Gastrointestinal stromal tumors (GISTs) are defined as CD117-positive primary, spindled or epithelioid, mesenchymal tumors of the gastrointestinal tract, omentum, or mesentery. While computed tomography (CT) is the recommended imaging modality for GISTs, overlap in imaging features between GISTs and other gastrointestinal tumors often make radiological diagnosis and subsequent selection of the optimal therapeutic approach challenging. Cinematic rendering is a novel CT post-processing technique that generates highly photorealistic anatomic images based on a unique lighting model. The global lighting model produces high degrees of surface detail and shadowing effects that generate depth in the final three-dimensional display. Early studies have shown that cinematic rendering produces high-quality images with enhanced detail by comparison with other three-dimensional visualization techniques. Cinematic rendering shows promise in improving the visualization of enhancement patterns and internal architecture of abdominal lesions, local tumor extension, and global disease burden, which may be helpful for lesion characterization and pretreatment planning. This article discusses and illustrates the application of cinematic rendering in the evaluation of GISTs and the unique benefit of using cinematic rendering in the workup of GIST with a specific emphasis on tumor characterization and preoperative planning.
