This issue of JVIM has standard articles on wireless EEG, clinicopathologic and MRI features of FIP, and the relationship
of brachycephaly in Persian cats with hydrocephalus.
One of the most common measurements taken in the
evaluation of brachycephaly and scaphocephaly is the cephalic ratio (cephalic index), which is a rather fancy term for the measurement taken by dividing the size of the widest part of a baby's skull by the longest part of the skull, in millimeters and multiplying by 100.
If you are thinking of purchasing a French Bulldog puppy, then you would be well advised to research the
subject of brachycephaly throughly.
Within each breed there is a tendency for the degree
of brachycephaly to become increasingly extreme over time.
