What does it mean when the report says C7 - T1 minimal annular bulge?

C7-T1 minimal annular bulge means that there is a slight outward protrusion of the soft, gelatinous substance (nucleus pulposus) inside the disc between the seventh cervical vertebra (C7) and the first thoracic vertebra (T1). This can cause irritation of the surrounding nerves, resulting in pain, numbness, and/or weakness in the neck, back, and/or arms.
