MRI features can help to confirm a diagnosis of progressive myelomalacia, but may not be accurate in dogs lacking characteristic clinical signs at the time of imaging

TL;DR:
MRI features can support the diagnosis in dogs with clinical evidence of progressive myelomalacia, and absence of these features supports absence of PMM at time of imaging, however, their absence does not reliably differentiate dogs with imminent progressive myELomalacia from other dogs with severe deficits following intervertebral disc extrusion.
