MRI.This diagnostic test uses a combination of large magnets and a computer to make detailed pictures of organs and structures within the body without the use of X-rays. It can find plaques or scarring caused by MS. Generally, a single attack along with certain patterns of changes in brain...
Historical survey confirms that, over the latter part of the 20th century, autoimmune-based diseases, including multiple sclerosis (MS), have shown a worldwide increase in incidence and prevalence. Analytical population studies have established that the
This technique is evaluated using ten real MRI data-sets with 10% used in the training of the textural-based SVM. The average results for the performance evaluation of the presented technique were 0.79 for dice similarity, 0.68 for sensitivity and 0.9 for the percentage of the detected lesion ...
40、a contrast agent to highlight active plaques and, by elimination, demonstrate the existence of historical lesions not associated with symptoms at the moment of the evaluation. Testing of cerebrospinal fluid obtained from a lumbar puncture can provide evidence of chronic inflammation in the central...

Our proposed MS-UNet is compared with several benchmarks on three public medical image segmentation datasets, including CT, MRI, and X-ray datasets. Finally, we have conducted an extensive ablation study on MS-UNet. 4.1. Datasets 4.1.1. Synapse The synapse multi-organ segmentation dataset [35...
We will define these evaluation metrics using the basic terms such as true positive, true negative, false positive, and false negative. In this study, the binary classification is considered where the CXRs are categorized into two classes: “normal” (no disease existence) and “abnormal” ( ...
(iii) normal X-ray, CT results, and normal MRI results or the presence of “dark disc”, “high imaging zone” or “modic change”[2]; and (iv) discographic results revealing abnormal morphology of the disc and induction of consistent pain, without a pain response in the adjacent ...
Fol- low-up was done subsequently in our outpatient depart- ment every 3 months with MRI scans. Tumor progression was defined by either clinical deterioration related to the spinal cord function, new contrast-enhancement or > 25% volume increase of resid- ual contrast enhancement. ...
