MRI Measurements of 5 significant variables and CM and syringomyelia status for example dogs A–N.

Comparison between 8 representative Griffons (A–H) with different degrees of CM and syringomyelia affectedness (0,1,2) and also mesaticephalic and brachycephalic dogs with different degrees of CM affectedness (0,1) but without syringomyelia. Angle 2 becomes more acute with CM and Angle 5 becomes more acute with brachycephaly and this is irrespective of the height of the rostral cranial fossa (F-diameter). Aust. Terrier = Australian Terrier.
