Transcranial Doppler ultrasonography (uses, limitations, and potentials): a review article

Abstract Background The additional information that transcranial Doppler can provide as part of a multimodal imaging protocol in many clinical settings has not been evaluated. Main body Transcranial is bedside procedure used to assess cerebral blood flow velocity via circulation and pulsatility index (PI). Many diseases lead vessels vasospasm subarachnoid hemorrhage trauma. Cerebral represented by abnormal elevation velocity. Intracranial pressure be monitored which reflects resistance vessels. ultrasonography also the unique modality for detection micro emboli high-risk patients. Also, it evaluation circulatory arrest with subsequent confirmation brain death Conclusion only diagnostic provides reliable assessment patterns real time. physiological obtained from TCD complementary anatomical details other neuroimaging modalities. relatively cheap, performed bedside, allows monitoring acute emergency settings.
