CT Spine (Per Part: Cervical, Thoracic, Lumbar)

CT Spine (Per Part: Cervical, Thoracic, Lumbar) – Detailed Overview

A CT Spine Scan is an advanced imaging technique used to evaluate the bones, joints, and soft tissues of the spine. It provides detailed cross-sectional images, making it highly effective for detecting fractures, degenerative changes, infections, tumors, and spinal trauma.

1. Types of CT Spine Scans & Their Indications

✅ CT Cervical Spine (C-Spine)

Indications:
🔹 Trauma – Cervical spine fractures, dislocations, ligamentous injuries
🔹 Degenerative Diseases – Disc bulges, osteophytes, cervical spondylosis
🔹 Tumors & Metastases – Bone tumors, secondary deposits
🔹 Congenital Abnormalities – Atlantoaxial instability, Klippel-Feil syndrome
🔹 Infections & Inflammation – Vertebral osteomyelitis, epidural abscess
🔹 Postoperative Assessment – Fusion, implants, screw placements

---

✅ CT Thoracic Spine (T-Spine)

Indications:
🔹 Trauma & Fractures – Compression fractures, burst fractures (e.g., in osteoporosis)
🔹 Tumors & Metastases – Spinal tumors, multiple myeloma involvement
🔹 Infections & Tuberculosis – Pott’s disease (spinal TB), osteomyelitis
🔹 Spinal Deformities – Scoliosis, kyphosis, congenital defects
🔹 Post-Surgical Evaluations – Spinal hardware assessment

---

✅ CT Lumbar Spine (L-Spine)

Indications:
🔹 Lower Back Pain & Radiculopathy – Herniated discs, nerve compression
🔹 Trauma & Fractures – Spondylolysis, spondylolisthesis, compression fractures
🔹 Degenerative Spine Disease – Lumbar spondylosis, facet arthropathy
🔹 Tumors & Infections – Primary spinal tumors, metastatic lesions, abscesses
🔹 Postoperative Follow-up – Fusion integrity, screw placement

2. Procedure & Technique

Patient Preparation:

✅ No fasting required for non-contrast scans
✅ IV contrast may be required for tumors, infections, or vascular pathology
✅ Patient lies supine with minimal movement to avoid motion artifacts

CT Protocol & Phases

🔹 Non-contrast Scan – Preferred for trauma, fractures, and degenerative diseases
🔹 Contrast-Enhanced Scan (CECT Spine) – Used for infections, tumors, or post-op evaluation
🔹 Thin-slice axial images with coronal & sagittal reconstructions

Field of View (FOV):

📌 Cervical Spine CT: C1–C7, includes occiput for upper cervical assessment
📌 Thoracic Spine CT: T1–T12, includes adjacent rib articulations
📌 Lumbar Spine CT: L1–L5, includes sacrum if necessary

3. Key Findings in CT Spine

✅ Traumatic & Fracture Findings:

• Cervical: Odontoid fracture, Jefferson fracture, Hangman’s fracture

• Thoracic: Compression fractures, burst fractures

• Lumbar: Spondylolysis, spondylolisthesis, vertebral body fractures

✅ Degenerative Changes:

• Disc Herniation – Protrusion, extrusion, compression of nerve roots

• Osteophytes & Spondylosis – Bony spurs causing nerve impingement

• Facet Joint Arthropathy – Joint space narrowing, sclerosis

✅ Infectious & Inflammatory Conditions:

• Osteomyelitis – Bone destruction, soft tissue swelling

• Spinal Tuberculosis (Pott’s Disease) – Vertebral collapse, paravertebral abscess

• Spondylodiscitis – Infection spreading between vertebral bodies

✅ Tumors & Metastases:

• Primary Bone Tumors – Osteosarcoma, chordoma

• Spinal Metastases – From lung, breast, prostate cancer

• Multiple Myeloma – Lytic lesions affecting vertebrae

4. Advantages of CT Spine

✔ Superior for bony structures & fractures compared to MRI
✔ Fast scan time (useful in trauma cases)
✔ Good for surgical planning & post-op assessment
✔ Available in emergency settings

5. Limitations & Considerations

❌ Radiation exposure (higher than MRI)
❌ Limited soft tissue detail – MRI is preferred for spinal cord, nerves, and disc pathology
❌ IV Contrast may be required for infection, tumor, or vascular assessment
