New trends in cerebral hemodynamics and neurosonology

Carotid and Vertebrobasilar Occlusive Disease. Overview of ultrasound in cerebrovascular disease patients (L.R. Caplan). Quantification of carotid stenosis: a fiction? (E.B. Ringelstein). Three-dimensional ultrasound imaging of carotid occlusive disease (A. Fenster et al. ). New developments in four-dimensional ultrasonography for the assessment of carotid disease (S. Meairs, M. Hennerici). Three-dimensional ultrasound angiography (power mode) for the quantification of carotid artery atherosclerosis (B. Griewing et al. ). Plaque volume measurements of carotid artery using a magnetic sensor system (A. Delcker). Ultrasound densitometric analysis of carotid plaque composition: patho-anatomic correlationR (Y. Beletsky et al. ). Diurnal systolic blood pressure variability is the strongest predictor of early carotid atherosclerosis (D. Sander, J. Klingelhofer). CW, PW and color Doppler for the evaluation of the carotid degree of stenosis (Ph. Arbeille et al. ). Assessing carotid artery stenosis by Doppler- and colour-coded duplex sonography (M. Goertler, B. Widder, U. Schuetz). Quantification of obstructions in distal vertebral arteries or basilar artery with extracranial duplex color-flow imaging (R. Schreiner et al. ). Hemodynamic factors and clinical course in patients affected by extracranial carotid occlusion (D. Giobbe, T. Angusti, G.C. Castellano). Long-term hemodynamic effects of internal carotid artery dissection (L. Motsch et al. ). Course of cerebral hemodynamics in carotid occlusion (C. Baracchini et al. ). Rationale of platelet pharmacology in haemodynamics (I. Jasinski, B. Kehrel). Collateral circulation and NIRS changes in patients for carotid endarterectomy (J.M.K. Lam et al. ). Early changes of haemodynamics after carotid endarterectomy (V. Zbornikova, L. Skoglund). High-dose heparin does not lead to better recanalisation of an occluded ICA (J.G. Heckmann et al. ). Asymptomatic carotid stenosis and the risk of stroke (The ACSRS Study): identification of a high-risk group (A.N. Nicolaides). II. Clinical Impact of Ultrasonography and Imaging Techniques. Functional MRI and PET activation studies on the human cortical motor system (H. Boecker). PET and migraine (C. Weiller). Cerebral blood flow (CBF) in chronic hydrocephalus: new aspects (P. Klinge-Xhemajli et al. ). Regional cerebral perfusion and its reserve compared to CT findings in 100 patients with cerebrovascular disease (M. Schreckenberger et al. ). Colour duplex measurement of total cerebral blood flow: reference data from childhood to adulthood (M. Schoning, P. Scheel, B. Hartig). Common carotid artery volume flow evaluation: comparison of color flow M-mode ultrasound and two-dimensional cine phase-contrast magnetic resonance imaging (K.W. Neff et al. ). Potential of transcranial Doppler and single photon emission computed tomography for assisting triage for thrombolytic trials in acute stroke (A.V. Alexandrov, D. Vital, M.D. Devous).
