MRI Dorsal / Dorso-Lumbar Spine Without Contrast

What the Scan Covers (D5–L2 Region)

• Dorsal (thoracic) spine: T5–T12 vertebrae that anchor the rib cage
• Dorso-lumbar junction: T12–L2 transition zone where the spine curves into the lower back
• Surrounding soft tissues: Spinal cord, nerve roots, intervertebral discs, ligaments, and blood vessels

• Vertebral alignment & curvature (kyphosis, scoliosis)
• Intervertebral disc height & hydration (dark on T1, bright on T2)
• Spinal canal diameter (normal ≥12 mm)
• Facet joints for arthritis or hypertrophy
• Ligamentum flavum thickness (can cause canal narrowing)
• Nerve root impingement or swelling

• Diagnose disc degeneration & herniation causing back or leg pain
• Rule out spinal stenosis (narrowing of the canal)
• Detect vertebral fractures from osteoporosis or trauma
• Identify congenital anomalies like spina bifida occulta
• Plan minimally invasive spine procedures or physiotherapy

• Zero radiation—safe for repeated follow-ups
• High-resolution soft-tissue contrast—superior to CT for discs & nerves
• Faster scan time—20–30 minutes vs. 45–60 minutes for contrast studies
• Lower cost—no need for IV contrast or post-procedure monitoring
• Same-day reporting—available within 2–4 hours at Cadabams Diagnostics

Pre-Requisites

• Remove all metal objects—jewelry, belts, hairpins
• Fasting not required—eat and drink normally
• Clothing: Change into cotton gown; avoid garments with metal zippers

Best Time

• Any time of day; avoid caffeine if you’re anxious
• Early morning slots reduce waiting time at Cadabams Diagnostics

Eligibility

• Most adults & seniors—check implant compatibility beforehand
• Pediatric cases—sedation available for children under 6

Procedure

1. Check-in & screening (5 min)
2. Lie supine on MRI table with cushion under knees
3. Coil placement over mid-lower back
4. 20–30 min scan—remain still; earplugs provided
5. Post-scan review—technologist verifies image quality

Caution

• Inform tech about tattoos (some inks contain metal)
• Pregnancy: Notify staff if you’re or might be pregnant

MRI Safety

• Pacemakers/ICDs: Most modern devices are MRI-conditional; inform Cadabams staff
• Metal implants: Joint replacements, screws, or cochlear implants need compatibility checks
• Claustrophobia: Open-bore MRI or mild sedation available on request
• Pregnancy: Generally safe after first trimester; consult your doctor

Limitations vs. Contrast-Enhanced Imaging

• Small tumors or active infections may be missed without contrast
• Inflammatory conditions like multiple sclerosis are better seen with gadolinium
