An MRI of the sacrum and coccyx provides detailed images of bone, bone marrow and surrounding soft tissues. It can detect fractures, marrow edema, tumors or metastases, infection (osteomyelitis/abscess), inflammatory sacroiliitis, degenerative changes, disc or nerve‑root compression and post‑traumatic coccygeal dislocation. It also shows soft‑tissue masses, cysts (e.g., Tarlov) and postoperative or congenital abnormalities.

An MRI of the lumbar and sacral spine images the lower back and tailbone to diagnose causes of persistent pain, sciatica, numbness or weakness. It detects disc herniation, spinal stenosis, nerve root compression, degenerative changes, infection, tumors, fractures or congenital abnormalities, and guides surgical planning and treatment decisions. It’s noninvasive and useful when X-rays or exams are inconclusive.

Cost varies widely by country and facility. In India a focused MRI for the coccyx typically costs about ₹2,000–₹8,000. In the UK it’s free on the NHS; private scans run roughly £150–£600. In the US private MRI prices usually range from about $400 to $3,000 (higher if contrast, advanced sequences, or hospital setting). Price depends on contrast, sequences and location.

Costs vary widely by country, facility, and whether contrast or private care is used. Typical ranges: India ~INR 1,500–8,000; UK free on the NHS but private ~£150–£700; USA about $400–$3,500 (out‑of‑pocket). Insurance often reduces patient cost; contrast studies and hospital outpatient settings raise fees. Always check local centres for exact pricing.

A coccyx (tailbone) MRI typically takes about 20–40 minutes of scanning time, with total appointment time often 30–60 minutes including positioning and paperwork. Duration varies with scanner strength, the number of imaging sequences, whether contrast is used, and patient factors (movement, ability to lie still). Protocols can be shorter or longer depending on clinical needs.

Spine MRI can detect herniated or degenerated discs, spinal stenosis and nerve‑root or spinal‑cord compression; fractures and bone‑marrow changes; infections such as discitis, osteomyelitis, and abscess; tumors (primary and metastatic); inflammatory disorders like ankylosing spondylitis; demyelinating disease (multiple sclerosis plaques); vascular malformations. It also shows degenerative joint disease, post‑operative changes, and congenital anomalies.
