What is desication with loss of the t2 disc signal?

Desiccation with loss of the T2 disc signal refers to a condition in which the intervertebral disc loses hydration and its normal signal intensity on T2-weighted MRI scans. T2-weighted images typically show high signal intensity in healthy discs due to their water content, but desiccation results in a decreased signal, indicating degeneration. This process is often associated with aging or disc pathology and can lead to increased disc stiffness and reduced cushioning, potentially contributing to pain and spinal instability.
