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 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 کاملRole of Transcranial Doppler Sonography in Confirmation of Brain Death
The aim of the study was to determine the specificity and sensitivity of Transcranial Doppler Sonography (TCD) as a confirmatory test for diagnosis of brain death and to assess the possibility of adding this test to the protocol for diagnosis of brain death in ICU. TCD examination was done in 20 patients (group I) with brain death confirmed either by clinical assessment and EEG (17 patients) or...
متن کاملTheory and Practice of MRA-Guided Transcranial Doppler Sonography
Despite consisting of 2 – 3% of total body mass, the brain accounts for ~20% of the body’s oxygen consumption and therefore must receive significant blood supply to maintain homeostasis (Ainslie & Duffin, 2009). This profound dependency on blood supply belies the brain’s apparent ability to regulate blood supply so tightly. Hence, the brain’s ability to regulate its blood supply has been, and s...
