Raised intra-cranial pressure by spectral Doppler on TCD, as calculated by pulsatility index. a Diffuse subarachnoid hemorrhage on CT head. b Spectral Doppler of MCA, demonstrating diastolic blunting secondary to raised ICP (pulsatility index = 4.31, ICP = 46 mmHg). c Following interventions to reduce ICP, there was normalization of diastolic flow in the MCA, and resolution of high ICP (pulsatility index = 1.65, ICP = 17 mmHg)
