Abstract
To explore the performance of improved watershed algorithm in processing magnetic resonance imaging (MRI) images and the effect of the processed images on the treatment of lumbar brucellar spondylitis (BS) with abscess by the posterior approach, the watershed algorithm was improved by adding constraints such as noise reduction and regional area attribute. 50 patients with abscessed lumbar disc herniation admitted to the hospital from January 2018 to January 2019 were selected, and all of them were examined by MRI. They were rolled into two groups in random. The treatment group (n = 25) accepted surgery with the aid of MRI images processed by the improved watershed algorithm, and the control group (Ctrl group) (n = 25) accepted surgery with the aid of unprocessed MRI images. The improved watershed algorithm can accurately segment the spine, and the segmentation results were relatively excellent. In contrast with the unprocessed MRI image, that processed by the improved watershed algorithm had a positive effect on the operation. In contrast with the Ctrl group, the visual analogue scale pain score (VAS), oxygen desaturation index (ODI), erythrocyte sedimentation rate (ESR), and high sensitivity C-reactive protein (CRP) were obviously lower (p < 0.05). The improved watershed algorithm proposed performs better in MRI image processing and can effectively enhance the resolution of MRI images. At the same time, the posterior approach has a good effect in the treatment of lumbar BS with abscess and is worthy of clinical promotion.
Highlights
With the rapid development of modern society, the pace of people’s lives is accelerating; at the same time, more and more people have the spinal diseases
Most commonly used intervertebral disc positioning and segmentation algorithms are grayscale features, Gbor features, and shape information. ey combine the algorithm with image features and prior information. e commonly used algorithms include methods based on the deformation models, Hough transformation method, wavelet transform, and watershed algorithm. e watershed algorithm is a processing method based on morphology
Image Segmentation Results. e same spine image was selected for corresponding processing, and the segmentation result is shown in Figure 1. e improved marked ridge algorithm did not have the problem of oversegmentation
Summary
With the rapid development of modern society, the pace of people’s lives is accelerating; at the same time, more and more people have the spinal diseases. On the basis of medical treatment of lumbar brucellosis spondylitis, surgical operations can directly reach the diseased vertebral body and intervertebral space, remove infected lesions, inflammatory granulation tissues, and abscesses, scrape off Contrast Media & Molecular Imaging the sclerotic bone, and create good conditions for bone healing in the bone graft area. It can effectively shorten the course of antibiotic treatment and reduce the incidence of adverse reactions. Traditional methods are prone to oversegmentation; in this study, the algorithm was improved
