Bilateral changes in muscle architecture of physically active people with chronic stroke: a quantitative muscle ultrasound study
Stroke is primarily regarded as a central nervous system (CNS) disorder, but post-stroke structural changes in skeletal muscles have been described. Imaging techniques such as Dual Energy X-ray Absorptiometry (DEXA) and Computed Tomography (CT) have revealed atrophy in several paretic side muscles of stroke survivors (English et al., 2010; Scherbakov et al., 2015). In addition to atrophy, increased intramuscular fat has been found in hemiparetic muscles of post-stroke patients (Ryan et al., 2002, Klein et al., 2010, Ryan et al., 2011).

EP 74. Comparison of freehand B-mode and power-mode 3D ultrasound for visualisation and grading of internal carotid artery stenosis
Currently, colour-coded duplex sonography (2D-CDS) is clinical standard for detection and grading of ICAS (1,2) as a relevant risk factor for ischaemic stroke (3,4). Unlike angiographic imaging modalities, 2D-CDS assesses ICAS by its haemodynamic effects rather than luminal changes1. Therefore, aim of this study was to evaluate freehand 3D ultrasound (3DUS) for direct visualisation and quantification of ICAS.

The role of neurovascular ultrasound in intensive care units
The neurovascular ultrasound methods are cheap and noninvasive methods that are performed at the bedside of critically ill patients. Transcranial Doppler sonography (TCD), transcranial color Doppler sonography (TCCD) and ultrasound examination of the neck vessels can provide valuable information for timely treatment decisions. In patients with acute stroke, TCD can detect intracranial arterial steno-occlusive disease and presence of collateral flow. The recanalization rate after reperfusion treatment can be monitored with serial TCD recordings in acute ischemic stroke.

107. Ultrasound investigations in sickle cell anemia. Initial assessment and follow up
This study was proposed to compare two different equipment: TCD (trans-cranial doppler) and TCCS (transcranial color-coded sonography) with or without using the angular correction, in a group of patients with the sickle cell anemia in order to identify the most suitable technique for the sampling of blood velocity (TAMM). 35 pediatric patients without previus history of neurological disease or transfusion were enrolled. Arteries examined were the middle cerebral artery, the anterior cerebral artery, the posterior cerebral and the basilar arteries. TAMM values greater than 200cm/s identify patients at high risk of stroke wh...

45. Patient presenting with transient phosphenes and headache: A case of fibromuscular dysplasia
Fibromuscular dysplasia (FMD), is a nonatherosclerotic, noninflammatory vascular disease commonly affecting the renal, extracranial carotid and vertebral arteries (VA). Etiology remains unknown. Clinical presentation is determined by distribution of arteries affected. Carotid artery involvement is associated with headache, TIA, stroke, pulsatile tinnitus, or may be asymptomatic. Treatment is being recommended in symptomatic cases. A 49-year-old Caucasian woman, was presented to our emergency department for transient phosphenes in right eye, followed by front-temporal headache. Cranial CT was normal, cervical duplex ultraso...
