Spine and vertebrae imaging Should you choose MRI or CT

Do you suffer from back or neck pain? Has your doctor recommended imaging of your spine or vertebrae? Spinal imaging is one of the most essential steps in diagnosing musculoskeletal and neurological problems, helping to identify the cause of pain, numbness, or stiffness.In this guide from "Dalili Medical," we provide everything you need to know about spinal scans: the types of imaging used, the differences between them, how the tests are performed, their common uses, and how safe they are.

✅ What Is Spinal Imaging?

Spinal imaging refers to a set of diagnostic tests used to obtain clear images of the vertebrae in the neck, mid-back, and lower back. These images help in diagnosing conditions such as:

• Herniated discs

• Osteoporosis and small fractures

• Arthritis and inflammation

• Spinal tumors or deformities

• Nerve or spinal cord compression

✅ Types of Spinal Imaging

1. X-Ray (Plain Radiography)

• Used to assess bone alignment, detect fractures, and identify spinal deformities such as scoliosis.
  ⚠️ Does not show detailed images of discs or nerves.

2. CT Scan (Computed Tomography)

• Produces cross-sectional images of the spine and is excellent for detecting small fractures or evaluating post-traumatic injuries.

3. MRI (Magnetic Resonance Imaging)

• The best choice for imaging soft tissues: spinal discs, spinal cord, nerves, and ligaments.

• Ideal for diagnosing disc herniation, nerve inflammation, or spinal tumors.

4. DEXA Scan (Bone Density Test)

• Measures bone density to evaluate osteoporosis, especially in elderly patients.

✅ When Is Spinal Imaging Recommended?

Your doctor may recommend spinal imaging in cases such as:

• Chronic neck or lower back pain

• Stiffness or difficulty moving

• Injuries due to falls or accidents

• Suspected herniated disc

• Weakness, tingling, or numbness in the limbs

• Spinal infections or autoimmune diseases

• Post-surgical follow-up

✅ Imaging Areas Based on Symptoms

Region	Common Indications
Cervical Spine	Neck pain, headaches, whiplash, trauma
Thoracic Spine	Postural deformities, mid-back pain
Lumbar Spine	Herniated discs, lower back pain, leg numbness
Sacrum/Coccyx	Pelvic pain, tailbone injury, after falls

✅ How Is the Scan Performed?

Preparation:

• Fasting is not usually required (except for contrast-enhanced MRI).

• Remove metal jewelry or clothing with zippers.

• Inform your doctor if you are pregnant or have metal implants.

During the Scan:

• You’ll be asked to lie on a table.

• Positions may change depending on the scan type.

• In some cases, a contrast dye may be injected to enhance nerve and tissue visibility.

Duration:

• X-ray: 5–10 minutes

• CT Scan: 10–20 minutes

• MRI: 30–60 minutes

---

✅ Is Spinal Imaging Painful or Risky?

• All imaging techniques are non-invasive and painless.

• CT scans involve low to moderate radiation exposure—should not be repeated unnecessarily.

• MRI is safer as it uses no radiation, but may not be suitable during the first trimester of pregnancy.

---

✅ Do All Spinal Issues Appear on Scans?

Not always. While X-rays can detect fractures or misalignment, more complex issues such as:

• Disc herniation

• Nerve inflammation

• Spinal cord tumors

...require an MRI for accurate diagnosis.

✅ CT Scan vs. MRI for Spine Imaging

Feature	CT Scan	MRI
Technology	X-rays	Magnetic fields

✅ Frequently Asked Questions (FAQ)

❓ Should I do the scan at a specialized center?
✅ Yes, to ensure high-quality images and precise interpretation.

❓ Do I need anesthesia?
❌ No. All procedures are done without anesthesia, except in cases like children or patients who cannot stay still during MRI.

❓ When will I get the results?

• X-Ray: Within 1 hour

• CT Scan: 2–3 hours

• MRI: 1–3 days

✅ Cost of Spinal Imaging in Egypt (2025)

Type of Scan	Approximate Price (EGP)
X-ray of the spine	200 – 400
CT Scan of vertebrae	700 – 1200
MRI of the spine	1500 – 3000

 

⚠️ Prices vary based on the center, use of contrast, and urgency.

✅ Final Thoughts

Spinal imaging is a key tool for diagnosing back and spinal conditions accurately. It helps your doctor select the most effective treatment plan tailored to your case.

✅ Always choose a certified imaging center and consult with your doctor to understand the results and next steps.

Remember: Early diagnosis is the first step toward effective treatment and long-term relief.
