Positional Magnetic Resonance Imaging (MRI)

DESCRIPTION

Positional magnetic resonance imaging (MRI) also known as kinetic or upright MRI allows imaging of individuals in a range of weight-bearing positions that replicate axial loading of the spine during normal activities such as sitting and standing. This procedure has been proposed as a diagnostic tool for individuals with position-dependent back pain. Determining the cause of back pain is a complex task and positional MRI is purported to be able to detect anatomic spinal anomalies that would otherwise not be detected by conventional (recumbent) MRI. 

POLICY

IMPORTANT REMINDERS

ADDITIONAL INFORMATION

The evidence is currently insufficient to evaluate whether the use of positional MRI improves health or treatment outcomes. Studies that correlate positional MRI findings with symptoms and outcomes of treatment are needed. Guidelines for interpreting positional MRI results have not been established due to the lack of data.
