Gadolinium-enhanced MR imaging and nephrogenic systemic fibrosis: retrospective study of a renal replacement therapy cohort.

Tara Anne Collidge, Peter Campbell Thomson, +5 authors G Roditi
Radiology
2007

PURPOSE To retrospectively compare the frequency of administration and cumulative dose of gadolinium-based contrast agent in dialysis-dependent patients who did and those who did not develop… (More)

Contrast-enhanced 3D MRA using SENSE.

Markus Weiger, Klaas P. Pruessmann, +4 authors Peter Boesiger
Journal of magnetic resonance imaging : JMRI
2000

Sensitivity encoding (SENSE) was used to improve the performance of three-dimensional contrast-enhanced magnetic resonance angiography (3D CE-MRA). Utilizing an array of receiver coils for… (More)

Elevated Troponin Levels Are Associated with Sympathoadrenal Activation in Acute Ischaemic Stroke

Mark G Barber, James J. Morton, Peter W Macfarlane, Nicola L Barlow, G Roditi, David Stott
Cerebrovascular diseases
2007

BACKGROUND It has been hypothesised that elevated serum troponin levels in acute stroke are due to myocardial damage caused by sympathoadrenal activation, which, in turn, may be due particularly to… (More)

Risk factors for NSF: a literature review.

Martin R. Prince, Hong Lei Zhang, G Roditi, Tim Leiner, Walter Kucharczyk
Journal of magnetic resonance imaging : JMRI
2009

Emerging evidence linking gadolinium-based contrast agents (GBCAs) to nephrogenic systemic fibrosis (NSF) has changed medical practice patterns toward forgoing GBCA-enhanced magnetic resonance… (More)

Accurate, practical and cost-effective assessment of carotid stenosis in the UK.

Joanna M. Wardlaw, Francesca M. Chappell, +11 authors Jacqueline Best
Health technology assessment
2006

OBJECTIVES To determine whether less invasive imaging tests [ultrasound (US), magnetic resonance angiography (MRA), computed tomographic angiography (CTA) and contrast-enhanced MRA (CEMRA)], alone or… (More)

Carotid artery stenosis: accuracy of noninvasive tests--individual patient data meta-analysis.

Francesca M. Chappell, Joanna M. Wardlaw, +8 authors Marc Stewart Randall
Radiology
2009

PURPOSE To find clinically relevant estimates of the accuracy of noninvasive imaging-Doppler ultrasonography (US), computed tomographic (CT) angiography, magnetic resonance (MR) angiography, and… (More)

Peripheral arterial disease: the evolving role of non-invasive imaging.

Andrew R Owen, G Roditi
Postgraduate medical journal
2011

Peripheral arterial disease is usually secondary to stenotic or occlusive atherosclerosis and is both common and increasing in western society. The majority of symptomatic patients have intermittent… (More)

LES of additive and non-additive pulsatile flows in a model arterial stenosis.

Md. Mamun Molla, Manosh Paul, G Roditi
Computer methods in biomechanics and biomedical…
2010

Transition of additive and non-additive pulsatile flows through a simple 3D model of arterial stenosis is investigated by using a large eddy simulation (LES) technique. We find in both the pulsatile… (More)

Renovascular imaging in the NSF Era.

G Roditi, Jeffrey Harold Maki, George Layson da Silva Oliveira, Henrik J. Michaely
Journal of magnetic resonance imaging : JMRI
2009

The detection of the association between nephrogenic systemic fibrosis (NSF), a rare but potentially life-threatening disease only encountered in patients with severely impaired renal function, and… (More)

Poor outcome in primary intracerebral haemorrhage: results of a matched comparison.

Mark G Barber, G Roditi, David Stott, Peter Langhorne
Postgraduate medical journal
2004

BACKGROUND Primary intracerebral haemorrhage (PICH) is associated with a poorer outcome than cerebral infarction. This study aimed to determine whether this is explained by the clinical severity of… (More)
