Trigeminal neuralgia model based on MR image and preparation method of trigeminal neuralgia model

Abstract

The invention provides a trigeminal neuralgia model based on an MR image and a preparation method of the trigeminal neuralgia model. Through an MR nerve imaging sequence, 3D high-resolution MRI scanning images of trigeminal nerves, adjacent blood vessels and a brain stem are acquired; acquired original image data are imported into modeling post-processing software; image fusion, segmentation and reconstruction are performed on the pressed trigeminal nerves, offending arteries and an adjacent brain stem structure to acquire a trigeminal neuralgia nerve blood vessel compression three-dimensionalanatomical model; a color 3D printer can be imported to print an individualized 3D printing solid model; a nerve blood vessel compression form and degree, complex walking and front and back as well as upper and lower spatial relationships of an adjacent structure are effectively displayed; the needs of accurate medical assessment and an operation are met; the trigeminal neuralgia model is used for preoperative planning, operation simulation and teaching training; the exploration time in a microvascular decompression operation is reduced; operation complications are reduced; and a medical training teaching effect is improved.

Description

technical field [0001] The invention belongs to the technical field of medical models, in particular to an MR image-based trigeminal neuralgia model and a preparation method thereof. Background technique [0002] Trigeminal neuralgia is the most common cranial nerve disease, manifested as sudden onset, sudden arrest, lightning-like, knife-like, burning-like, intractable, unbearable severe pain in the distribution area of ​​the trigeminal nerve on the head and face, periodic attacks, As a result, the patient's spirit is listless, his actions are cautious and fearful of seizures, and even the pain is too painful, which seriously affects the quality of life. [0003] Microvascular decompression surgery to isolate the responsible blood vessels and nerves is currently the preferred surgical treatment for primary trigeminal neuralgia. However, in clinical practice, conventional MR high-resolution images are 2D images. There are individual differences in the distribution and distr...

AI Technical Summary

Problems solved by technology

However, in clinical practice, conventional MR high-resolution images are 2D images. There are individual differences in the distribution and distribution of the superior cerebellar artery, anterior inferior cerebellar artery, posterior inferior cerebellar artery, and adjacent veins. In some cases, the anatomical branches and courses vary greatly. It can be multi-branched, and there is more than one neurovascular compression in the same responsible vessel. It is difficult to quantify the degree of neurovascular contact or compression, and it is difficult to describe the shape and spatial relationship of the neurovascular compression. The three-dimensional visualization of the three-dimensional relationship of nerve space is limited, which leads to certain difficulties and challenges in the accurate preoperative evaluation of trigeminal neuralgia, the accurate implementation of microvascular decompression and effective medical teaching and training
