A dorsolumbar spine MRI is a magnetic resonance scan of the thoracic (dorsal) and lumbar spine. It produces detailed images of vertebrae, intervertebral discs, spinal cord, nerve roots and adjacent soft tissues, helping diagnose disc herniation, spinal stenosis, infection, tumors, fractures and inflammatory or degenerative conditions. The non-invasive test uses magnetic fields and radio waves; contrast may be given when indicated.

Costs for an MRI dorsal (thoracic) spine with contrast vary widely by country and facility. Rough estimates: India ₹3,000–15,000; UK private £200–£700; USA $500–$5,000 depending on outpatient centre versus hospital. Final price depends on contrast, facility type, location and insurance. Prices often include radiologist fees and contrast agent costs; check local imaging centres for exact charges.

Contrast dye for MRI of the lumbar spine is typically a gadolinium-based contrast agent (e.g., gadobutrol, gadoterate, gadopentetate) given intravenously (commonly 0.1 mmol/kg). It enhances detection of tumors, infection, inflammation, and helps distinguish scar from recurrent disc disease. Gadolinium agents are generally safe but require kidney function assessment (eGFR) and cautious use in pregnancy or severe renal impairment.

A dorsal spine MRI is a magnetic resonance imaging scan of the thoracic (dorsal) spine that produces detailed images of vertebrae, intervertebral discs, spinal cord, and nerve roots. It’s used to evaluate pain, trauma, disc herniation, infection, tumors, inflammation, or demyelinating disease. The non-invasive test uses magnetic fields (no ionizing radiation), often takes 20–60 minutes, and sometimes uses contrast for better detail.

The dorsolumbar spine is the transitional segment where the lower thoracic (dorsal) vertebrae meet the upper lumbar vertebrae, often called the thoracolumbar region. It typically includes the junction around T10–L2. This area endures substantial mechanical stress and is a common site for fractures, pain, and degenerative changes because it bears load and enables trunk movement.

Contrast (gadolinium) is not routinely required for lumbar spine MRI—most exams for back pain or sciatica use non‑contrast scans. Contrast is added to evaluate tumors, infection, inflammation, or to distinguish postoperative scar from recurrent disease, or when vascular detail is needed. Discuss risks (kidney function, rare allergic reactions, pregnancy considerations) with your referring clinician or radiologist.
