Thoracic Spine MRI

MRI of the thoracic spine (T1-T12) without contrast. Assesses vertebral bodies, discs, spinal cord, and paraspinal structures through the mid-back region.

The thoracic spine MRI covers the twelve thoracic vertebrae from T1 to T12, including the thoracolumbar junction that is a common site for compression fractures. Sagittal T1, T2, and STIR sequences provide an overview of vertebral body alignment, disc morphology, and spinal cord calibre across the entire thoracic region. Axial images at selected levels assess the cord and canal dimensions. The thoracic spine is less commonly imaged than the cervical or lumbar segments, but the examination is important for mid-back pain with potential radiculopathy, suspected thoracic disc herniation, vertebral compression fractures, and screening for spinal metastases. STIR sequences are particularly sensitive to acute fractures and marrow infiltration. The examination is also indicated for scoliosis evaluation and for patients with systemic conditions such as ankylosing spondylitis that affect the thoracic spine. Scan duration is approximately 25 minutes.
