Does an MRI show back problems?

MRIs can over-diagnose back problems and may lead to invasive and often unnecessary treatment. The use of MRI should be limited to cases with clear warning signs such as weakness in the extremities, history of cancer, fevers, infection or loss of bowel or bladder control.

How long does an MRI of the back take?

This may be the case if: Your history and physical examination show signs of a serious problem, such as a fracture, tumours, infection, or nerve damage. You are older than 70.

Do pinched nerves show on MRI?

MRI is sensitive to changes in cartilage and bone structure resulting from injury, disease, or aging. It can detect herniated discs, pinched nerves, spinal tumors, spinal cord compression, and fractures.

Does an MRI show nerve damage?

An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.

Can MRI show pinched nerve?

MRI scans which show soft tissues, such as nerves and discs, are generally preferred over CT scans which show bony elements. Advanced imaging can show exactly which nerve or nerves are being pinched and what is causing the nerve to be pinched.
