What is Lumbar Spine AP & Lateral View X-Ray Scan?

Definition and imaging views explained

A lumbar spine AP & lateral view X-ray scan is a two-angle radiograph of the five vertebrae (L1–L5) and the lumbosacral junction.

• AP (Antero-Posterior): X-ray beam passes from front to back, showing vertebral alignment and disc spaces.
• Lateral: Beam enters from the side, revealing spinal curvature and facet joints.

Difference between AP and lateral projections

How X-rays capture the lumbar spine

Low-dose ionising radiation passes through soft tissue and is absorbed differently by bone, producing high-contrast images on a digital detector.

Types of Lumbar Spine AP & Lateral View X-Ray Scan

Digital vs conventional X-ray

• Digital (DR): Instant images, 30 % lower dose, electronic storage.
• Conventional film: Rare today; longer processing time.

Weight-bearing vs supine options

• Weight-bearing images joints under gravity—detects subtle instability.
• Supine is default when standing is painful.

Optional extended views (lumbosacral spine)

If symptoms extend to the tailbone, we add lumbosacral views to include L5–S1.

---

• Vertebral alignment: Straight vs rotated
• Disc space height: Uniform narrowing suggests degeneration
• Bone density: Osteopenia or fracture lines
• Spinal curvature angles: Normal lordosis vs flattening or scoliosis

---

• Back pain evaluation: Rule out fracture or arthritis
• Trauma or injury assessment: After accidents or heavy lifting
• Pre-surgical planning: Accurate vertebral landmarks before procedures
• Monitoring degenerative changes: Track progression of known conditions

---

Common symptoms that warrant the scan

• Lower-back pain lasting >2 weeks
• Pain radiating to legs or buttocks
• Numbness or tingling in feet - Sudden injury from fall or heavy lifting

Age groups and risk factors

• 20–40 years: Disc herniation from sports or desk jobs
• 40–65 years: Degenerative disc disease, early arthritis
• 65+ years: Osteoporotic compression fractures

Referral criteria for doctors

General physicians, orthopaedists, physiotherapists, and chiropractors may refer based on red-flag symptoms or failure of conservative care.

Benefits of Taking the Lumbar Spine AP & Lateral View X-Ray Scan

• Fast and non-invasive imaging: In and out in under 15 minutes
• Cost-effective diagnostic tool: Fraction of the price of MRI or CT
• High-resolution images: Zoom, pan, and measure digitally for pinpoint accuracy

---

Illnesses Diagnosed with Lumbar Spine AP & Lateral View X-Ray Scan

• Spondylolisthesis: Forward slippage of one vertebra
• Compression fractures: Collapse of vertebral body, common in osteoporosis
• Degenerative disc disease: Narrowed disc spaces and bone spurs
• Spinal stenosis: Narrowed spinal canal visible on lateral view

Clothing guidelines

Wear loose cotton clothes. Remove belts, zips, and underwire bras. Gowns are provided.

Metal object removal

Take off jewellery, keys, and cards with magnetic strips. Mobile phones stay outside.

What to inform the technologist

• Surgical implants or rods in the back
• Recent barium study (wait 48 hrs)
• Any mobility or claustrophobia concerns

---

Pre-requisites for Lumbar Spine AP & Lateral View X-Ray Scan

• Doctor’s prescription requirement: Mandatory—bring a printed or digital copy.
• Pregnancy declaration form: Required for women of child-bearing age.
• Insurance documentation if applicable: Cashless cards, pre-authorisation letters.

---

Best Time to Take the Lumbar Spine AP & Lateral View X-Ray Scan

• Morning vs evening scheduling: Mornings have shorter queues; evening slots suit working professionals.
• Post-injury timing recommendations: Within 48–72 hours to capture acute changes.
• Follow-up scan intervals: 3–6 months for monitoring degeneration or healing.

---

Eligibility for Lumbar Spine AP & Lateral View X-Ray Scan

Pediatric considerations

Performed only under paediatric protocol with reduced dose and shielding.

Geriatric patient adaptations

Extra cushions, seated lateral views if standing is unsafe.

Contraindications checklist

• Confirmed pregnancy (unless life-saving)
• Severe obesity exceeding table limits (rare)

Procedure for Taking a Lumbar Spine AP & Lateral View X-Ray Scan

Step-by-step positioning guide

1. Registration: Verify identity and prescription.
2. Changing room: Remove metal objects, wear gown.
3. AP view: Stand/sit facing the detector, arms on hips.
4. Lateral view: Turn sideways, arms raised away from torso.
5. Image capture: Hold breath for 1 second while X-ray fires.
6. Review: Technologist checks clarity; repeats only if needed.

Duration of the scan

Entire process: 5–10 minutes. Actual exposure: <1 second.

Patient comfort measures

• Adjustable table heights
• Soft foot mat for weight-bearing comfort
• Clear instructions in English, Hindi, and Kannada

---

Caution Before Taking the Test

Radiation safety protocols

• ALARA principle: As Low As Reasonably Achievable dose.
• Shielding: Lead apron for pelvic organs when appropriate.

Special considerations for pregnant women

Defer non-urgent scans or use MRI. Urgent cases use shielding and minimal views.

Claustrophobia or mobility concerns

Open room design, seated options, and wheelchair accessibility.
