[[Magnetic resonance imaging]] (MRI) is used to evaluate the lumbar region for bone degeneration or injury or disease in tissues and nerves, muscles, ligaments, and blood vessels. MRI scanning equipment creates a magnetic field around the body strong enough to temporarily realign water molecules in the tissues. Radio waves are then passed through the body to detect the “relaxation” of the molecules back to a random alignment and trigger a resonance signal at different angles within the body. A computer processes this resonance into either a three-dimensional picture or a two-dimensional “slice” of the tissue being scanned, and differentiates between bone, soft tissues and fluid-filled spaces by their water content and structural properties. This noninvasive procedure is often used to identify a condition requiring prompt surgical treatment.

Overview

MRI is be helpful in the diagnosis of the underlying cause of back pain. Findings on MRI suggestive of the cause of back pain include soft tissue lesions, nerve compression, malignancy, and/or inflammatory lesions. MRI is indicated in back pain if any of following red flags are present, history of cancer, unexplained weight loss, significant trauma, motor weakness, sensory loss, urinary/fecal incontinence.
