We describe the use of serial transcranial Doppler studies to evaluate neurovascular disease in three girls presenting with acute stroke due to primary cerebral vasculitis (n = 2) and West Nile vasculitis (n = 1). Correlation of abnormal findings on transcranial Doppler sonography was compared with those of MR angiography and conventional angiography in each child. All three girls had left midd...
background: in patients with acute stroke and middle cerebral artery (mca) stenosis, microembolic signals (mes) can predict further cerebral ischemia. therefore, this study was designed to evaluate the prevalence of mes by transcranial doppler (tcd) in patients with mca stenosis under treatment of aspirin or clopidogrel. methods: a randomized clinical trial was performed on 40 patients with acu...
The Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts in the field of vascular ultrasonography (US) to come to a consensus regarding Doppler US for assistance in the diagnosis of carotid artery stenosis. The panel's consensus statement is believed to represent a reasonable position on the basis of analysis of available literature and panelists' experience. Key ...
OBJECTIVE To record the correlation between color power Doppler sonographic measurement of breast tumor vasculature and immunohistochemical analysis of microvessel density for the quantitation of angiogenesis. METHODS Women with palpable breast masses scheduled for excision biopsy were scanned with two- and three-dimensional color power Doppler sonography before and after the administration o...
BACKGROUND AND PURPOSE The noninvasive diagnosis of cerebral vasospasm with the use of conventional transcranial Doppler ultrasonography (TCD) is based on a velocity study of the middle cerebral artery (MCA). The authors report a prospective comparative study between transcranial color-coded sonography (TCCS), conventional transcranial Doppler (TCD), and angiography in the diagnosis of cerebral...
Response In their letter, Bladin and Burns repeat previously published arguments, 1 without considering the particulars of our study. 2 They have cited us incorrectly several times, suggesting that they did not read our paper accurately: 1. "An absolute precision of ±0.1 mm. .. was. .. assumed by the authors." In fact, we stated that "the calipers could be adjusted in 0.1-mm graduations." 2. Th...
