Lumbar disc herniation (LDH) is common among spinal pathologies, which can lead to LBP and radiculopathies [1, 2]. Reliance on T2-weighted images for the detection of disc herniations may result in decreased sensitivity for free disc fragments, which often demonstrate high signal intensity on T2-weighted images. The disc fragment can compress the spinal nerve root, causing pain and symptoms similar to herniated discs.Disc herniation is displacement of disc material like nucleus pulposus, parts of the annulus fibrosus and cartilage, beyond the limits of the intervertebral disc space. 의학적인 용어로는 , , , , , 으로 여러 가지 .
