MR image-based piriformis syndrome model and preparation method thereof

Abstract

The invention provides an MR image-based piriformis syndrome model and a preparation method thereof, and the method comprises the steps: obtaining 3D high-resolution MRI scanning images of sciatic nerves, piriformis and adjacent muscles through an MR nerve imaging sequence, importing the obtained original image data into modeling post-processing software, perfroming image fusion, segmentation andreconstruction on pressed sciatic nerves, piriformis and adjacent muscle structures to obtain a piriformis syndrome three-dimensional anatomical model, importing the piriformis syndrome three-dimensional anatomical model into a color 3D printer to print an individualized 3D printing entity model, and effectively displaying the sciatic nerve compression form, walking and the spatial relation between the walking and the adjacent piriformis structures; so that the product meets the requirements of precise medical evaluation and operation, is used for preoperative planning, operation simulation and medical teaching training, and improves 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 piriformis syndrome model and a preparation method thereof. Background technique [0002] Piriformis syndrome is a common disorder that causes acute and chronic sciatica. When the piriformis muscle is damaged, hyperemia, edema, spasm, adhesion and contracture occur, the muscle space or the upper and lower holes of the muscle become narrow, and the nerves and blood vessels passing through it are squeezed, resulting in a series of clinical symptoms And body syndrome is called piriformis injury syndrome. [0003] Electrophysiological, CT, and ultrasonographic examinations are difficult to achieve intuitive 3D visualization of peripheral neuropathy, injury site, and degree. MR neuroimaging high-resolution sequences have improved the display rate of peripheral neuropathy. However, conventional MR high-resolution images are 2D images, which cannot fully and i...

AI Technical Summary

Problems solved by technology

MR neuroimaging high-resolution sequences have improved the display rate of peripheral neuropathy. However, conventional MR high-resolution images are 2D images, which cannot fully and intuitively visualize the shape of the sciatic nerve and the adjacent piriformis muscle and the three-dimensional spatial relationship between them, resulting in piriformis. Accurate evaluation and effective medical teaching and training of muscular syndrome face certain difficulties and challenges
