From: Application study of 3D LAVA-Flex on lumbar intervertebral disc degeneration
a Sagittal T2WI image; b sagittal 3D LAVA-Flex image. L1–2, L2–3, and L3–4 intervertebral discs (Pfirrmann grade II): the distinction of nucleus pulposus and annulus fibrosus was clear on T2WI and LAVA-Flex images. L4–5 (Pfirrmann grade IV) and L5–S1 intervertebral disc (Pfirrmann grade V): the distinction of nucleus pulposus and annulus fibrosus was unclear on T2WI image, and it was blurred or lost on 3D LAVA-Flex image
