abstract background: transcranial doppler ultrasonography results have not been previously studied in among iranian sickle cell anemia patients. the present study was performed to evaluate the pattern of intracranial flow velocities among iranian children with sickle cell anemia and the hematological parameters that can affect the time-averaged mean of maximum velocity in major intracranial art...

Blood flow in the pulmonary artery was studied by Doppler colour flow mapping and cardiac catheterisation in 19 patients with a ductus arteriosus and different pulmonary artery pressures. In the four patients with normal pulmonary artery pressures colour Doppler flow mapping showed multicoloured wide and long systolic and diastolic jets in the pulmonary artery. In the 15 patients with raised pu...

The velocity of blood flow in the ophthalmic artery was measured with a transcranial Doppler ultrasound (2 MHz). Sixty patients with chronic open angle glaucoma (COAG), 42 patients with normal tension glaucoma (NTG), and 35 normals were studied. Peak flow velocity (peak), mean-enveloped velocity (mean) and diastolic velocity were compared in the three groups. The COAG patients and the NTG patie...
