The neurological determination of death (NDD) is primarily considered to be clinical.
However, situations may arise where confounding factors make this clinical assessment …

Since the establishment of the concept of declaring death by brain criteria, a large extent of
variability in the determination of brain death has been reported. There are no standardized …

Objective: Cerebral blood flow tests have increasingly been advocated for the confirmation
of brain death (BD). Four-vessel angiography has been considered the most reliable …

Objective–The reported sensitivity of transcranial Doppler ultrasonography (TCD) for
confirming brain death (BD) ranges from 91% to 100%. We assessed the frequency and …

Abstract Introduction Transcranial Doppler (TCD) can detect the cerebral circulation arrest
(CCA) in brain death. TCD is highly specific, but less sensitive because of false-negatives …

自Rune Aaslid 在1982 年发明经颅多普勒超声(TCD) 并将其应用于临床以来, 已经历了28
年的历史, 从20 世纪80 年代末以超声学和神经病学专家华扬教授和黄一宁教授为代表的学者将 …

Background Brain death diagnosis relies on clinical signs, but confirmatory tests are legally
mandatory in some countries. In France, transcranial Doppler (TCD) is not recognized as a …

The “brain death” standard as a criterion of death is closely associated with the need for
transplantable organs from heart-beating donors. Are all of these potential donors really …

Abstract Background Transcranial Doppler (TCD) ultrasonography to demonstrate cerebral
circulatory arrest (CCA) is a confirmatory test for brain death (BD). The primary aim of this …

Neurosonological studies, specifically transcranial Doppler (TCD) and transcranial color-
coded duplex (TCCD), have high level of specificity and sensitivity and they are used as …
