It is long known that findings in conventional anatomical imaging do not necessarily correlate with clinical symptoms in patients suffering from unilateral lumbosacral radicular syndrome (LRS), which regularly occurs in the context of disc herniation due to degeneration with unilateral nerve contact. The present study investigates the performance of quantitative imaging by using magnetic resonance neurography (MRN) using T2 mapping for LRS diagnostics at the lumbosacral plexus. As the main finding, it shows that nerves affected by degenerative disc herniation are characterized by elevated T2 values, in contrast to contralateral nerves or a non-affected control level.
