The quality of images produced by Magnetic Resonance Imaging (MRI) continues to advance to help doctors visualize injury in greater detail. Detectable injury makes proving accident liability easier.
When MRI Is Preferred Over X-rays
Unlike x-rays, which use ionizing radiation to produce images, Magnetic Resonance Imaging (MRI) uses radio waves and a strong magnetic field. Because it gives clear pictures of soft-tissue around bones, MRI is considered the best choice for examining the body’s joints, the spine for disc disease, and soft tissues of the arms, legs, hands, and feet.
Higher Quality Images from 3T MRI
Until recently, MRI scanners performed at 1.5 Tesla (T) (Tesla measures the strength of a magnetic field). More sensitive 3T MRI scanners, which provide higher-quality images, are now used to more accurately see:
- Brain and spinal cord injury
- Fractures not seen on x-ray
- Herniated discs
- Injury and disease in the neck
- Injuries to tendons, ligaments, and muscles
- Swelling or bleeding in tissues in and around bones and joints
Challenges with Diagnosing TBI
Traumatic brain injury is notoriously difficult to diagnose. The brains of concussion patients often look normal on CT scans, the most common test after head trauma, and symptoms such as memory loss and emotional difficulty can be subtle, even to a neurologist.
Objective Evidence from 3T MRI
In many cases involving traumatic brain injury (TBI), the results of regular, routine diagnostic tests such as standard MRIs and CT Scans, will appear normal. In the absence of visual signs, symptoms such as post-traumatic amnesia, changes in mood and personality, and changes in attention and concentration are considered subjective evidence. The higher quality clear images shown in greater detail produced by 3T MRI scanners can provide valuable objective evidence to prove injury in these cases.
