“…In that study (17), 16 or 32 projections (in four of 38 patients and 34 of 38 patients, respectively) were available for rotational angiography. Similar conclusions were previously described by Bosanac et al (18).…”

“…Elgersma et al (17) and Bosanac et al (18), however, have demonstrated clearly that the limited number of projections available with conventional DSA may lead to an underestimation of stenosis when rotational angiography is used as the reference standard. This is because stenoses typically develop asymmetrically rather than in a concentric manner (22), and thus the narrowest portion of the residual lumen and, by inference, the maximum ICA stenosis will not always be depicted at conventional DSA in two projections (17).…”

“…IAA itself is changing, with the recent introduction of rotational IAA. As highlighted earlier, comparison of rotational IAA and conventional three-view IAA suggests that the latter underestimates the degree of stenosis in the 70-99% group, 90,91,127 which may explain why US and MRA appear to overestimate the degree of stenosis; it is difficult to discern which tests are correct, but it is important to remember that the relationship between stroke risk and percentage stenosis was calculated from conventional three-view IAA. Therefore, any systematic difference in the estimate of stenosis by another imaging technique would need to be factored into the equation relating stenosis to stroke risk to correct for this difference.…”

“…Although IAA is the reference standard, there is recent evidence that patients with 70-99% ICA stenosis are at risk of underdiagnosis of stenosis degree by conventional (three-view) IAA compared with three-dimensional (3D) rotational angiography (a recently introduced IAA technique). 90,91,127 It is therefore likely that these patients 'overdiagnosed' by MRA or US were in fact being underdiagnosed by IAA. Which is right?…”

HTA on CD is currently free of charge worldwide.The website also provides information about the HTA Programme and lists the membership of the various committees. HTA NHS R&D HTA ProgrammeT he research findings from the NHS R&D Health Technology Assessment (HTA) Programme directly influence key decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC) who rely on HTA outputs to help raise standards of care. HTA findings also help to improve the quality of the service in the NHS indirectly in that they form a key component of the 'National Knowledge Service' that is being developed to improve the evidence of clinical practice throughout the NHS.The HTA Programme was set up in 1993. Its role is to ensure that high-quality research information on the costs, effectiveness and broader impact of health technologies is produced in the most efficient way for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care.The HTA Programme commissions research only on topics where it has identified key gaps in the evidence needed by the NHS. Suggestions for topics are actively sought from people working in the NHS,...

“…This position is, however, increasingly contentious. Arterial stenosis on DSA, particularly when eccentric, shows poor correlation with the reduction in luminal cross sectional area that is best demonstrated using three dimensional techniques and which is the determinant of haemodynamic effect 5 6. DSA is also invasive, with attendant risks of haemorrhage, vessel injury, cholesterol embolism syndrome, and contrast induced nephropathy 7.…”

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

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 claudication and only a minority (<2% and typically those with diabetes mellitus or renal failure) progress to critical limb ischaemia, heralded by the onset of rest pain and/or tissue loss. Imaging is largely reserved for patients with disabling symptoms in whom revascularisation is planned. In these patients, accurate depiction of the vascular anatomy is critical for clinical decision making as the distribution and severity of disease are key factors determining whether revascularisation should be by endovascular techniques or open surgery. Driven by advances in technology, non-invasive vascular imaging has recently undergone significant refinement and has replaced conventional digital subtraction angiography for many clinical indications. In this review, the relative merits and limitations of duplex ultrasound, CT angiography, and magnetic resonance angiography are discussed, emerging imaging techniques are described, and complications relating to the use of intravascular contrast agents are highlighted.
