Transcranial sonographic images obtained in the suboccipital window (longitudinal plane) showing color Doppler mapping of the basilar artery of canines (A) pinscher, weighing 2.850 kg (B) Shih Tzu, weighing 9.4 kg. Note the difficulty in acquiring the color Doppler signal in brachycephalic dogs of larger size and body weight compared to mesaticephalic dogs of smaller weight and miniature size. Doppler adjustments (A) Gain = 60%; PRF = 4.3 kHz; (B) Gain = 60%, PRF = 2.9 KHz
