CT Scan
The dorsal, or thoracic, spine is the 12-vertebra stretch of your mid-back that anchors your ribcage, and it's imaged far less often than the neck or lower back simply because problems here are less common. This scan is typically ordered after chest or back trauma to check for a vertebral fracture, or when persistent mid-back pain raises concern for a structural cause a plain X-ray hasn't clarified. Thoracic disc herniation itself is uncommon compared with the neck and lower back, and when it does happen, most cases sit low in this segment rather than near the top. CT is well suited here because it shows bone detail - fracture lines, alignment, compression - in a way plain X-ray often cannot.
This scan covers the twelve thoracic vertebrae, the discs between them, and the surrounding bone in cross-section. It's used mainly to check for vertebral fractures, alignment problems, and degenerative changes in the mid-back. Your doctor reads it alongside your symptoms and the mechanism of any injury.
The dorsal spine sits between your neck and lower back - twelve vertebrae that anchor your ribs and support the middle of your torso. It doesn't move as much as the neck or lower back, which is part of why injuries and disc problems here are less frequent.
Trauma is the most common reason: a fall, an accident, or a direct blow to the back can fracture a thoracic vertebra, and CT shows the fracture pattern and any bone displacement clearly. It's also used when mid-back pain persists without a clear cause on X-ray.
Thoracic disc herniation happens less often than in the cervical or lumbar spine. When it does occur, roughly three-quarters of cases are found below the eighth thoracic vertebra, most often around T11-T12, and many are picked up incidentally on a scan done for another reason rather than because of clear symptoms.
- Vertebral fractures and compression - Spinal alignment after injury - Degenerative bone changes - Disc-related findings in the lower thoracic region
Ask your doctor whether this plain scan is enough, or whether contrast is needed.
It covers all twelve vertebrae of the thoracic, or dorsal, spine - the section between your neck and lower back that anchors your ribcage.
If your pain or injury sits specifically in the mid-back, this scan targets that region directly. It's ordered less often than lumbar or cervical CT mainly because injuries and disc problems are less common here.
It's less common than in the neck or lower back, and many cases cause no symptoms at all, turning up only when a scan is done for another reason.
Yes, it uses X-rays, and the mid-back requires imaging through the ribcage and chest, so ask your doctor how this factors into your specific situation.

Not necessarily. Many dorsal spine CTs, especially for suspected fracture, are done without contrast dye. Your doctor decides based on what's being evaluated.
It can show structural causes like fractures, alignment problems, or degenerative changes. If your pain has a soft-tissue or nerve-related cause, your doctor may also consider an MRI.
A chest CT looks broadly at the lungs and chest organs, while this scan focuses specifically on the bones and discs of the thoracic spine. Your doctor orders whichever fits the question being asked.
