Transcranial Doppler sonography: adding to the toolbox.
rely on indirect evidence of nodal metastases. These include nodal enlargement, three or more borderline–sized nodes in a primary drainage pathway, and a nodal morphology showing a change from an elliptical to a spherical shape. The development of accurate radiologic criteria is important since 25% or more of patients presenting with head and neck cancer and no clinically palpable neck disease ...
متن کاملTranscranial Doppler sonography in fulminant hepatic failure.
UNLABELLED The clinical course of patients with fulminant hepatic failure (FHF) is often worsened by the presence of cerebral edema and endocranial hypertension. In spite of the multiple studies using Transcranial Doppler Sonography (TCDS), few have shown the cerebral blood flow (CBF) pattern among patients with encephalopathy resulting from FHF. OBJECTIVE Our objective was to characterize th...
متن کاملTranscranial doppler sonography diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine
Background: An imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. The purpose of this study was to determine the transcranial doppler sonography (TDS) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. Methods: This study was carried out on 46 pa...
متن کاملAngle-corrected imaging transcranial doppler sonography versus imaging and nonimaging transcranial doppler sonography in children with sickle cell disease.
BACKGROUND AND PURPOSE Nonimaging transcranial Doppler sonography (TCD) and imaging TCD (TCDI) are used for determination of the risk of stroke in children with sickle cell disease (SCD). The purpose was to compare angle-corrected, uncorrected TCDI, and TCD blood flow velocities in children with SCD. MATERIALS AND METHODS A total of 37 children (mean age, 7.8 +/- 3.0 years) without intracrani...
متن کاملCoregistration of transcranial Doppler - sonography and EEG in the diagnostic procedures of detection of brain death
Brain death (BD) diagnosis is the clinical assessment of the irreversible loss of function of the entire brain, including the brainstem. Transcranial Doppler (TCD) examination is used in several countries as a confirmatory test to assess cerebral circulatory arrest (CCA), but is not feasible in patients with absent temporal bone windows. TCD is highly specific, but less sensitive because of fal...
