The right ventricle is located from the 7 to 11 o’clock position (the right ventricle does not extend to the apex of the heart) (Figure 2-14). The right atrium is located at the 9 to 11 o’clock position (see Figure 2-14). However, a PA view is required to confidently diagnose cardiac enlargement. In general, dogs with heart enlargement are at greater risk for heart failure, but only 30% of dogs with asymptomatic DMVD develop clinical signs and require heart failure therapy. The term fusiform gyrus is used variably but typically indicates a central portion of the lateral occipitotemporal gyrus … The T 1-weighted images (panel E) revealed a 2-cm isointense to white matter lesion in the right central gyrus with surrounding T 1 hypointensity comparable to gray matter.

If the CTR is <50% on either a Posterior - Anterior (PA) or an Anterior - Posterior (AP) view, then the heart size is within normal limits. Hypoglycemic coma induces a purely neuronal lesion of the neocortex (layers 2 and 3), the hippocampus (neurons in the subiculum and the CA1 region and granule cells at the crest of the dentate gyrus), and the dorsolateral crescent of the caudoputamen in rat brains.
