“…17 Populationbased differences may be a factor in the heterogeneity seen in CE MRA studies, with two studies that reported recruiting an appropriate patient spectrum reporting the lowest sensitivity and specificity in their groups. 9,70 One of these studies also reported that clinical data were not available when interpreting scans, 70 which may also be a factor in lower accuracy. The major factor in spectrum-related heterogeneity is likely to be the proportion of patients at each stage of the disease process included in the studies.…”

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 NIHR Health Technology Assessment ProgrammeT he Health Technology Assessment (HTA) programme, now part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the costs, effectiveness and broader impact of health technologies 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 research findings from the HTA Programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service'. The HTA Programme is needs-led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects. First is the commissioned route. Suggestions for research are actively sought from people working in the NHS, the public and consumer groups and professional bodies such as r...

Purpose: To report our initial experience implementing a noncontrast-enhanced electrocardiograph (ECG) gated fast spin echo magnetic resonance angiography (MRA) technique for assessment of the calf arteries. Materials and Methods:Noncontrast MRA images of 36 clinical patients examined over a 6-month period were evaluated by two radiologists for length and degree of stenosis of arterial segments. Diagnostic confidence in the technique was also recorded. The reference standard was a consensus reading by both radiologists using the noncontrast technique combined with two gadoliniumenhanced techniques: bolus-chase and time-resolved imaging.Results: For stenosis evaluation the noncontrast technique demonstrated accuracy 79.4% (1083/1364), sensitivity 85.4% (437/512), and specificity 75.8% (646/ 852). The sequence demonstrated high negative predictive value (92.3%, 646/700). The technique had serious artifacts leading to poor diagnostic confidence in 17 patients (47.2%). These included motion (n ϭ 7) and artifacts specific to the sequence, including inaccurate trigger delays (n ϭ 5), linear artifact (n ϭ 7), and vessel blurring (n ϭ 5). When only patients in whom there was satisfactory diagnostic confidence were considered, accuracy, sensitivity, and negative predictive value were 92.2% (661/717), 92.4% (158/171), and 97.5% (503/ 516), respectively. Conclusion:Our results indicate that when technically successful, noncontrast-enhanced MRA using ECG-gated fast spin echo can provide accurate imaging of the calf and pedal arteries. However, further development and optimization are needed to improve the robustness of the technique.

Comparison of MR Angiography Versus Digital Subtraction Angiography as a Basis for Planning Treatment of Lower Limb Occlusive Disease

Abstract: The accuracy of MRA for the detection of significant lesions is comparable to DSA. Basing the therapeutic strategy solely on the results of MRA can reduce the number of DSAs by three quarters, but at the risk of incurring lesion overestimation in approximately 17%.
