How to read lumbar mri introduction A healthcare modality introduced in the 1980s called magnetic resonance imaging (MRI) unleashed a new era in medicine. MRI uses radio waves to look for lesions and abnormalities in bones and soft tissues of the spine. Sports medicine providers should be familiar with the process of reading a lumbar spine MRI.
This post does not serve as a comprehensive guide and does not cover all aspects or possibilities. As with all previously discussed imaging modalities, assessing a lumbar MRI may be taught in a variety of ways. Most providers will have a systemic way to go through each level from proximal to distal or vice versa.
A systematic approach can encourage a thorough evaluation of the spine and can help avoid overlooking portions of the anatomic evaluation when scrutinizing an MR imaging evaluation of the lumbar spine. There are two basic types of MRI images that differ by the timing of the radiofrequency pulses, named T1-weighted images and T2-weighted images. T1 images highlight the adipose or fatty tissue..
T2 images highlight water more than adipose within tissues. The contrast between these tissues creates the contrast of MRIs. The cerebrospinal fluid will show up dark on a T1 image and light on a T2 image.
One other specialized image that may be used are STIR (Short Tau Inversion Recovery) images, usually on the sagittal view. STIR images suppress the signal from fat, making fluid-filled areas, inflammation, and edema more prominent. This is achieved by using inversion pulses and short inversion times to create high contrast between fat and other structures.
If you are experiencing symptoms that may be related to how to read lumbar mri, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
