Answer

CT scanning provides much better bony detail of irregular lytic lesions, sclerosis, disk collapse, and disruption of bone circumference. [36]

Low-contrast resolution provides a better assessment of soft tissue, particularly in epidural and paraspinal areas.

CT scanning reveals early lesions and is more effective for defining the shape and calcification of soft-tissue abscesses. In contrast to pyogenic disease, calcification is common in tuberculous lesions.
