Dynamic Imaging Important – Dynamic Spine Models to Match Ongoing Findings
Upright MRI dynamic imaging entered the scene in the 2000’s. Since then, controversy of its value has been under fire. Some believe that the .6 Tesla power of the FONAR MRI does not provide images of the same resolution as the conventional 1.5 Tesla recumbent MRI. However, mounting evidence is starting to take shape and it is difficult to argue how the upright MRI is not important when looking at patients in a weight bearing mode–and finding spondylolisthesis otherwise undetected.
Medserena Upright MRI Centre is one of those leading facilities that continues to reveal spinal findings that often go undetected by conventional lie down MRI. In a recent case study, a 74 year old lady that underwent a laminectomy surgery 7 years ago was unable to walk without pain.
After a work-up by the team they looked at imaging the spine in a vertical fashion–compared to conventional lying down. This is what they found.
And when the patient was imaged in a seated position, this is what they saw–a slippage of L4 on L5:
And when the patient bent backwards while sitting, stenosis was revealed. You can see the hourglass narrowing.
This is an example of how dynamic MRI imaging can play a crucial role in determining a patient’s problems. This revealed problem can now be diagnostic to help guide the treatment plan whether through conservation means or surgical intervention.
Dynamic Disc Designs develops models with load in mind through careful construction of a dynamic annulus and nucleus. To have a model to explain and demonstrate these kinds of pathologies is very helpful to both clinicians and patients. Our list of spondylolisthesis models is just one example how Dynamic Disc Designs is working to make a clinical difference through education. Furthermore, our Lumbar Spinal Stenosis Model demonstrates narrowing in extension as the ligamentum flavuum buckles onto itself.
