Hi, welcome to HCM
C for cervical and T for thoracic vertebra. In cervical spine
there mild degereative changes as intervertebral disc
mild herniation between C2-C3 and C5-C6 vertebra, but it is not significant.
In thoracic veterbra , disc is just diffusely spread knoen as diffuse bulge , it is just causing mild indentation of intraspinal fluid, it is also not significant.
Hope you have got your answer.
