| 摘要 |
The present invention provides a method for determining the cerebral hemodynamic model for depression, using carotid duplex ultrasound to establish percent stenosis of a right external carotid artery and a left external carotid artery, and transcranial Doppler ultrasound instrument to measure mean flow velocity within the cerebral arteries including the right and left internal carotid arteries, right and left middle cerebral arteries, right and left anterior cerebral arteries, right and left posterior cerebral arteries, and basilar artery. Percent carotid stenosis and mean flow velocity values in cerebral arteries are used to determine the cerebral hemodynamic model associated with depression in men and women, respectively. |
