High-Intensity Zones in Dogs with Lumbosacral Intervertebral Disc Degeneration: Insights from MRI and Histopathological Findings

Diagnosing and managing lumbosacral pain in dogs remains a clinical challenge, necessitating comprehensive diagnostic approaches. Magnetic resonance imaging (MRI) plays a pivotal role in identifying structural abnormalities associated with intervertebral disc (IVD) degeneration. This retrospective study explores the presence of high-intensity zones (HIZ) in the dorsal annulus fibrosus (AF) of the lumbosacral region in dogs, correlating MRI findings with histopathological features.
