“…The authors found that the sensitivity and specificity for detecting these renal artery stenoses were 93% and 98%, respectively. Snidow et al 106 examined 32 patients using breath-hold CEMRA and compared the results with CA. The CEMRA protocol was intended primarily to evaluate the aorta and iliac inflow, with the parameters selected to include a screening study of the renal arteries.…”

Or contact Direct Mail Works (see contact details above) by email, post, fax or phone. 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...

“…Some key developments include the advent of 1) high-performance gradient hardware capable of providing repetition times (TR) and echo times (TE) on the order of a few milliseconds, making it possible to acquire moderate resolution CE-MRA images within a breath-hold; 2) real-time fluoroscopic monitoring eliminating the guesswork involved in timing the bolus arrival in the target vasculature (8,9); and 3) centric phase-encode acquisition schemes that capture the arterial enhancement associated with the first pass of the gadolinium (Gd) contrast, with minimal venous contamination even in scans with long acquisition times (10)(11)(12)(13). These developments have contributed to the improved robustness of CE-MRA, and numerous published studies have shown high sensitivity and specificity of CE-MRA for evaluating renal artery disease (1)(2)(3)(4)(5)(6)(7). Despite these advances, in a recent prospective multicenter study of 402 patients suspected of having renal artery disease, Vasbinder et al (14) found that the sensitivity and specificity of CE-MRA was only 62% and 84%, respectively, even in experienced hands.…”

Purpose: To assess the effect of attaining higher spatial resolution in contrast-enhanced magnetic resonance angiography (MRA) of renal arteries using parallel imaging, sensitivity encoding (SENSE), by comparing the SENSE contrast-enhanced (CE) MRA against a conventional CE-MRA protocol with identical scan times, injection protocol, and other acquisition parameters. Materials and Methods:Numerical simulations and a direct comparison of SENSE-accelerated versus conventional acquisitions were performed. A total of 41 patients (18 male) were imaged using both protocols for a direct comparison. Both protocols used fluoroscopic triggering, centric encoding, breath-holding, equivalent injection protocol, and lasted %30 seconds.Results: Simulated point-spread functions were narrower for the SENSE protocol compared to the conventional protocol. In the patient study, although the SENSE protocol produced images with lower signal-to-noise ratio (SNR), image quality was better for all segments of the renal arteries. In addition, ringing of kidney parenchyma and renal artery blurring were significantly reduced in the SENSE protocol. Finally, reader confidence improved with the SENSE protocol.Conclusion: Despite a reduction in SNR, the higher-resolution SENSE CE-MRA provided improved image quality, reduced artifacts, and increased reader confidence compared to the conventional protocol.

Three-dimensional gadolinium-enhanced MR angiography for aortoiliac inflow assessment plus renal artery screening in a single breath hold.

Abstract: This breath-hold protocol improves the accuracy of aortoiliac inflow assessment, but low resolution limits evaluation of small renal arteries.
