Deep brain tumor and white matter fiber bundle relation model and preparation method thereof

Abstract

The invention provides a deep brain tumor and white matter fiber bundle relation model and a preparation method thereof, and aims to obtain 3D high-resolution scanning images of deep brain tumors, adjacent white matter fiber bundles and brain parenchyma through an MR multi-modal imaging sequence. The obtained original image data are input into modeling post-processing software, and image fusion, segmentation and reconstruction are carried out on deep brain tumors, internal hemorrhage, peripheral edema, adjacent functional fiber bundles and brain parenchyma structures to obtain a deep brain tumor three-dimensional anatomical model; and the model can be imported into a color 3D printer to print an individualized precise medical 3D printing solid model for the brain tumor. The front-and-backand up-and-down spatial relationship between white matter fiber bundles such as brain tumor and adjacent key visual bundles, cortical spinal cord bundles and corpus callosum and brain parenchyma is accurately positioned. The occurrence probability of postoperative visual and dyskinesia is reduced, and the requirements of precise medical evaluation and operation are met. The model is used for preoperative planning and operation simulation, serves as a precise medical teaching training model, and improves the medical training teaching effect.

Description

technical field [0001] The invention belongs to the technical field of medical models, in particular to a model of the relationship between deep brain tumors and white matter fiber bundles and a preparation method thereof. Background technique [0002] Traditional microsurgery for deep brain tumors has a low total resection rate and a high morbidity rate, and postoperative permanent neurological dysfunction is likely to occur. How to remove the tumor safely and accurately to the greatest extent is particularly important. Deep brain tumors are more common in glioma, metastatic tumor, lymphoma, etc. Since the tumor is located in the deep brain parenchyma and deep in the cortex of the functional area, the risk of surgery is high; how to remove the tumor accurately, safely, quickly and completely has always troubled the nerves. surgeon. [0003] In clinical practice, there are individual differences in the course of the subcortical conduction pathway-white matter fiber bundles....

AI Technical Summary

Problems solved by technology

[0003] In clinical practice, there are individual differences in the course of the subcortical conduction pathway-white matter fiber bundles. The white matter fibers around the tumor are pushed, squeezed, interrupted and destroyed, and the three-dimensional relationship between the tumor and nerve fibers is limited in visualization. , Clinically, different neurosurgeons and medical students have different spatial imaginations, and the existence of influencing factors such as difficulty in understanding the three-dimensional space of the structure of the surgical area only on the two-dimensional level has led to accurate preoperative evaluation of deep brain tumors, Accurate implementation of intraoperative tumor resection and effective medical surgery training and medical teaching practice face certain difficulties and challenges
