Many tests of specific ‘executive functions’ show deficits after frontal lobe lesions. These deficits appear on a background of reduced fluid intelligence, best measured with tests of novel problem… Expand
Attentional functions of parietal and frontal cortex.
A model of normal attentional function, based on the concept of competitive parallel processing, is used to compare attentional deficits following parietal and frontal lobe lesions. Measurements are… Expand
A comprehensive study of clinical, biochemical, radiological, vascular, cardiac, and sleep parameters in an unselected cohort of patients with acromegaly undergoing presurgical somatostatin receptor…

CONTEXT Attainment of safe GH and IGF-1 levels is a central goal of acromegaly management. OBJECTIVE The aim of this study was to determine the extent to which reductions in GH and IGF-1… Expand
Detection and evaluation of intracranial aneurysms with 16-row multislice CT angiography.
AIM The aim of this study was to assess the usefulness of 16-row multislice CT angiography (CTA) in evaluating intracranial aneurysms, by comparison with conventional digital subtraction angiography… Expand
Wegener granulomatosis: MR imaging findings in brain and meninges.
PURPOSE To determine the spectrum of intracranial magnetic resonance (MR) imaging appearances of Wegener granulomatosis. MATERIALS AND METHODS MR imaging studies in 19 patients with Wegener… Expand
Diffusion tensor imaging of brain tumours at 3T: a potential tool for assessing white matter tract invasion?
AIM To determine whether diffusion tensor imaging (DTI) of brain tumours can demonstrate abnormalities distal to hyperintensities on T2-weighted images, and possibly relate these to tumour grade. … Expand
Imaging the vertebral artery
Although conventional intraarterial digital subtraction angiography remains the gold standard method for imaging the vertebral artery, noninvasive modalities such as ultrasound, multislice computed… Expand
Imaging of compressive vertebral haemangiomas
Compressive vertebral haemangiomas (VHs) are rare. Correct preoperative diagnosis is useful both for operative planning (since compressive VHs are extremely vascular lesions) and to allow… Expand
Assessment of quantitative computed tomographic cerebral perfusion imaging with H2150 positron emission tomography
Abstract Assessment of quantitative cerebral blood flow on a conventional fast CT machine without the use of specialized equipment may be valuable in the investigation of acute stroke and head… Expand
Contrast-enhanced MR angiography for carotid disease
Objective: To compare contrast-enhanced MR angiography (CEMRA) with intra-arterial digital subtraction angiography (DSA) for evaluating carotid stenosis. Methods: A total of 167 consecutive… Expand
