Background In atherosclerosis, arterial wall thickening and stiffening precede luminal narrowing. MRI is well-validated for imaging vessel wall thickness (VWT) and stiffness expressed in pulse wave velocity (PWV, defined as the propagation speed of the pressure or flow wave through the aorta). Contrast-enhanced MR angiography (CEMRA) has evolved into a reliable tool for stenosis detection in pe...

Dates to which data relate Effectiveness data in the principal pilot study corresponded to patients examined between April and September 1997. Effectiveness data in the validation pilot study corresponded to patients examined between May and October 1997. Some effectiveness data were based on assumptions from two studies published in 1995 and 1997. Resource consumption data were based on a surv...

Cerebral hyperperfusion syndrome is a recognized complication of carotid endarterectomy. Various studies have documented an incidence of 0.3 to 1.2%. It occurs in the setting of sudden reperfusion of a chronically hypoperfused hemisphere. We present here a case of a 48-year-old lady who developed cerebral hyperperfusion syndrome three weeks after undergoing a carotid endarterectomy for high-gra...

In order to identify the potential factors involved in the development of acute progressive cerebral infarction (PCI), the association between potential risk factors and extra- and intracranial arterial lesions was investigated. A total of 608 patients underwent cerebral angiography to analyze the morphological characteristics between the PCI and NPCI groups. In addition, data from numerous cas...

A 70-year-old woman with unilateral pulsatile tinnitus was relieved of the complaint after carotid endarterectomy. Internal carotid artery stenosis presenting with pulsatile tinnitus is rare. Endarterectomy can relieve symptoms if the correct diagnosis is made.

background: stroke is a multifactorial disorder, the most common cause being arterial occlusion. transcranial doppler ultrasonography (tcd) is a common non-invasive method available for assessment the arterial blood flow of the brain. objective: assessment the hemodynamic parameters of cerebral arteries, using tcd device in patients suffering ischemic stroke. materials and methods: this descrip...

OBJECTIVE To determine the frequency, level and flow patterns of lower limb arterial insufficiency in diabetic patients on Doppler ultrasound study. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Radiology Department, Civil Hospital, Karachi, from February 2007 to September 2008. METHODOLOGY One hundred adult diabetic patients with suspected peripheral vascular insufficie...

BACKGROUND In order to differentiate between the different causes of intracranial stenosis, we compared the diagnostic results of transcranial color-coded duplex (TCCD) sonography with the recently developed 3D high-resolution black blood MR sequence. METHODS We studied retrospectively 20 patients referred to our hospital after acute ischemic stroke who were diagnosed with intracranial stenos...
