Key result
Contrast-enhanced magnetic resonance angiography provides high sensitivity and specificity for detecting significant carotid artery stenosis, serving as a reliable non-invasive alternative to digital subtraction angiography.
Why the study?
Non-invasive imaging modalities have progressively replaced digital subtraction angiography for carotid artery stenosis due to high cost and risk, warranting an evaluation of contrast-enhanced magnetic resonance angiography performance compared to other modalities.
Does contrast-enhanced magnetic resonance angiography accurately assess carotid artery stenosis compared to other imaging modalities in patients with suspected carotid disease?

CE-MRA is a highly sensitive, non-invasive imaging modality for evaluating severe carotid artery stenosis that can serve as a safe alternative to digital subtraction angiography, particularly for patients with contraindications to iodinated contrast.
Should not yet change carotid imaging practice; leaves open need for prospective validation of contrast-enhanced MRA.
important markers for future cerebro-vascular events, including plaque composition, presence and state of the fibrous cap (FC), intraplaque haemorrhage, plaque ulceration and plaque location. All of these factors, therefore, need to be taken into account for a correct diagnostic and preventive approach aimed at risk stratification and treatment planning to reduce the incidence and severity of acute cerebrovascular disease. ree large multi-centric randomized studies, NASCET (North American Symptomatic Carotid Endarterectomy Trial), ECST (European Carotid Surgery Trial) and ACAS (Asymptomatic Carotid Athero-Sclerosis Group), provided cut-off values stenosis degree indicating possible benefits of carotid endarterectomy (CEA). e most used methods to quantify the degree of carotid artery stenosis are North American Symptomatic Carotid Endarterectomy Trial (NASCET) and European Carotid Surgery Trial (ECST), both evaluating the degree of stenosis as the percentage reduction in the linear diameter of the artery. In addition, in both NASCET and ECST trials, stenosis degree was determined by conventional angiography, since Computed Tomography Angiography (CTA) and Magnetic Resonance Angiography (MRA) were not available at that time. cently, the reference imaging technique in assessing the degree of carotid stenosis was only Digital Subtraction Angiography (DSA). However, it has been claimed that advanced non-invasive imaging modalities including Doppler Ultrasound (DUS), MRA and CTA have progressively replaced the diagnostic role of DSA. 4 This is mainly due to its high cost and greater risk. In addition, these in vivo techniques assist in analysing plaque morphology and its characteristics. This literature review will highlights the performance characteristics of contrast enhanced -MRA compared to other imaging modalities in the diagnosis of carotid artery stenosis.

Alhashlan et al. (2023) conducted a review in Carotid artery stenosis. Contrast-enhanced magnetic resonance angiography (CE-MRA) vs. Other imaging modalities (DSA, CTA, DUS, TOF-MRA) was evaluated on Diagnostic accuracy (sensitivity and specificity) for carotid artery stenosis. Contrast-enhanced magnetic resonance angiography provides high sensitivity and specificity for detecting significant carotid artery stenosis, serving as a reliable non-invasive alternative to digital subtraction angiography.
