Three-dimensional reconstruction nerve models are classically obtained from two-dimensional ages of “visible human” frozen sections. However, because of the flexibility of nerve tissues and smal color differences compared with surrounding tissues, the integrity and validity of nerve tissues can be impaired during mil ing. Thus, in the present study, we obtained two-dimensional data from a healthy volunteer based on continuous CT angiography and magnetic resonance myelography. Semi-automatic segmentation and reconstruction were then conducted at different thresholds in different tissues using Mimics software. Smal anatomical structures such as muscles and cervical nerves were reconstructed using the medical computer aided design module. Three-dimensional digital models of the cervical nerves and their surrounding structures were successful y developed, which al owed visualization of the spatial relation of anatomical structures with a strong three-dimensional effect, distinct appearance, clear distribution, and good continuity, precision, and integrality. These results indicate the validity of a three-dimensional digital visualization model of healthy human cervical nerves, which overcomes the disadvantages of mil ing, avoids data loss, and exhibits a realistic appearance and three-dimensional image.
