Figure 5From: Validation of a magnetic resonance imaging guided stereotactic access to the ovine brainstemMagnetic resonance images and macroscopic samples for target comparison. Needle placement error was calculated comparing the coordinates of the planned target site and the contrast bloom on magnetic resonance images (a, b, c) and assessed subjectively comparing the location of the toluidine stain on macroscopic samples with the planned target sites (a', b', c').Back to article page
