FIG 2. Patient with a high bilateral PI (aPI, 1.96; uPI, 1.72) with symmetrical flow velocities: (aVm, 28 cm/s; uVm, 29 cm/s). Center, CT scan shows a large hematoma (87.8 mL), a hypoattenuating lesion of 36.3 mL, and a midline shift of 0.2 cm; Left, Doppler recording corresponding to the right hemisphere; Right, Doppler recording corresponding to the left hemisphere.
