Computer aided diagnosis of degenerative intervertebral disc diseases from lumbar MR images
نویسندگان
چکیده
This paper presents a novel method for the automated diagnosis of the degenerative intervertebral disc disease in midsagittal MR images. The approach is based on combining distinct disc features under a machine learning framework. The discs in the lumbar MR images are first localized and segmented. Then, intensity, shape, context, and texture features of the discs are extracted with various techniques. A Support Vector Machine classifier is applied to classify the discs as normal or degenerated. The method is tested and validated on a clinical lumbar spine dataset containing 102 subjects and the results are comparable to the state of the art.

Demographic Characteristics and Family History of Lumbar Problems in Candidates for Lumbar Disc Degenerative Diseases Surgery
Background and Aim: Previous studies have reported the important effect of age, sex, heredity, and occupational status on intervertebral degenerative dick diseases, which are among the most important causes of low back pain. However, their results are not always so conclusive. This study was performed to investigate the demographic characteristics and family history of lumbar problems in patien...
متن کاملGuidelines for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 6: magnetic resonance imaging and discography for patient selection for lumbar fusion.
Discography is an exquisitely sensitive but not specific diagnostic test for the diagnosis of discogenic low-back pain. The restriction of the definition of a positive discographic study to one that elicits concordant pain from a morphologically abnormal disc improves the definition's accuracy. Fusion surgery based on discography alone, however, is not reliably associated with clinical success....
متن کاملDegenerative Disc Disease: A Review of Cell Technologies and Stem Cell Therapy
Background & Aim: Low back pain is broadly documented as one of the most widespread pathologies in the advanced domain. Although the reasons of low back pain are uncountable, it has been meaningfully related to intervertebral disc degeneration. Present therapies for Intervertebral Disc (IVD) degeneration such as physical therapy and spinal fusion reduce symptoms' severity, but do not treat the ...
متن کاملMeasuring diffusion of solutes into intervertebral disks with MR imaging and paramagnetic contrast medium.
BACKGROUND AND PURPOSE Experimental studies have shown that solutes diffuse more slowly into degenerated intervertebral disks than into normal disks. A noninvasive clinical study of diffusion in intervertebral disks is not generally available. Our purpose was to evaluate contrast-enhanced MR images to study diffusion in normal and degenerated lumbar intervertebral disks. METHODS The change in...
متن کاملEnd Plate Disproportion and Degenerative Disc Disease: A Case-Control Study
STUDY DESIGN Case-control. PURPOSE To determine whether a disproportion between two neighboring vertebral end plates is associated with degenerative disc disease. OVERVIEW OF LITERATURE Recently, it has been suggested that disproportion of the end plates of two adjacent vertebrae may increase the risk of disc herniation. METHODS Magnetic resonance (MR) images (n=160) with evidence of grad...
