Evaluation of the intracranial circulation provides valuable information in the diagnosis and prognosis of various intracranial abnormalities and may influence patient management. Technical advances in magnetic resonance angiography (MRA) have improved the accuracy of this technique in various clinical situations, such as aneurysms, arterial and venous(More)
Growth failure is a common observation in children with end-stage liver disease (ESLD). The liver is an important endocrine organ producing potent anabolic growth factors such as IGF-I (insulin-like growth factor-I) and its major binding-proteins, called IGFBP-1, -2 and -3. Circulating IGF-I and IGFBP-3 levels are low in children with chronic liver failure(More)
Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those(More)
Accurate radiographic diagnosis is a cornerstone of the clinical management and outcome prediction of the head-injured patient. New technological advances, such as multi-detector computed tomography (MDCT) scanning and diffusion-weighted magnetic resonance imaging (MRI) have influenced imaging strategy. In this article we review the impact of these(More)
Technical advances in MR angiography (MRA) have improved the sensitivity and the accuracy of this technique in the evaluation of vascular stenoocclusive disease of the brain. In many centers, due to its non-invasive and non-ionizing character, MR angiography has already replaced conventional angiography for the screening of intracranial vascular disease.(More)
