[Abstract] Objective To comparatively analyze the visualization differences between cinematic volume rendering technique (CVRT) and maximum intensity projection (MIP) in imaging lumbosacral plexus nerve sheath tumors, and further explore the clinical potential of CVRT in preoperative tumor assessment, treatment planning, and intraoperative injury reduction.Materials and Methods Retrospective analysis of 33 patients with lumbosacral plexus nerve sheath tumors, and all of them underwent three-dimensional fast spin echo short-time flip recovery sequence imaging (3D-STIR-SPACE) after enhancement. 3D-STIR-SPACE images were used as the original images, and were processed by maximum density projection MIP and CVRT, respectively. Overall image quality (OIQ), lumbosacral plexus (LSP) versus tumor display sharpness, LSP versus tumor spatial location resolution, and image diagnostic confidence level (DCL) of MIP and CVRT images were evaluated using a 4-point scale by two investigators. The performance scores of MIP and CVRT images were statistically analyzed using the non-parametric Wilcoxon signed rank test. The intra-class correlation coefficient (ICC) was used to assess the agreement between the two methods, CVRT and MIP, respectively, and the surgical results in determining the size and location of the tumor and its relationship with the LSP.Results Compared with MIP images, CVRT images obtained superior image quality, LSP with tumor display clarity and spatial location resolution, and very high diagnostic confidence, and both were significantly different (P < 0.05). In the consistency analysis, CVRT images exhibited ICC values that were comparable to those of MIP images (CVRT: ICC = 0.929 to 0.957; MIP: ICC = 0.878 to 0.922). The consistency between the results derived from CVRT image analysis and the surgical outcomes was at least equivalent to or better than that obtained from MIP image analysis (CVRT vs. MIP, ICC values: 0.988 vs. 0.969, 1.000 vs. 1.000, 0.943 vs. 0.807).Conclusions Compared with MIP, CVRT provides a clearer depiction of the anatomical relationship between the tumor and the lumbosacral plexus nerve, providing more imaging information for clinical diagnosis and treatment.
