A kind of trigeminal neuralgia model based on mr image and preparation method thereof

Abstract

The present invention provides a trigeminal neuralgia model based on MR images and a preparation method thereof. Through MR neuroimaging sequences, 3D high-resolution MRI scanning images of the trigeminal nerve, adjacent blood vessels, and brainstem are obtained, and the obtained original image data is imported into modeling The post-processing software performs image fusion, segmentation, and reconstruction of the compressed trigeminal nerve, responsible blood vessels, and adjacent brainstem structures to obtain a three-dimensional anatomical model of trigeminal neuralgia and neurovascular compression, which can be imported into a color 3D printer to print an individualized 3D printed solid model. Effectively display the shape, degree, complex course of neurovascular compression and the front-back, upper-lower spatial relationship of adjacent structures, meet the needs of precise medical assessment and surgery, and be used for preoperative planning, surgical simulation, and teaching training, and reduce the risk of microvascular decompression surgery. Exploring time, reducing surgical complications, and improving the teaching effect of medical training.

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
