“…These methods have undergone notable development over recent years, particularly CTA and MRA; however, despite these developments, invasive DSA remains the gold standard DSA is the gold standard for comprehensive CA assessment but is not readily available. CTA can examine intra‐ and extracranial arteries simultaneously, has brevity, is good for both stroke treatment and prevention, but requires contrast and exposes to radiation. MRA is radiation‐free, but costly, requires contrast, less accurate, and is time consuming. …”

Ultrasound assessment of carotid arteries: Current concepts, methodologies, diagnostic criteria, and technological advancements

Following cardiac disease and cancer, stroke continues to be the third leading cause of death and disability due to chronic disease in the developed world. Appropriate screening tools are integral to early detection and prevention of major cardiovascular events. In a carotid artery, the presence of increased intima‐media thickness, plaque, or stenosis is associated with increased risk of a transient ischemic attack or a stroke. Carotid artery ultrasound remains a long‐standing and reliable tool in the current armamentarium of diagnostic modalities used to assess vascular morbidity at an early stage. The procedure has, over the last two decades, undergone considerable upgrades in technology, approach, and utility. This review examines in detail the current state and usage of this integrally important means of extracranial cerebrovascular assessment.

“…10 CE-MRA helps to overcome these limitations. 7,11 Several studies revealed that CE-MRA was similarly accurate to CTA for evaluating carotid stenosis but was more accurate than CDUS. [7][8][9] In most of the previous studies, radiation-induced CA and VA stenosis has been evaluated by ultrasonography and DSA in head and neck cancers, 2-4 but few studies have assessed stenosis by CE-MRA.…”

“…Contrast enhanced 3D MRA has been shown to have high sensitivity and specificity for the determination of stenoses and occlusions of the internal carotid artery. 17,18 Accurate determination of the degree of stenosis at the carotid bifurcation and/or the internal carotid artery is crucial for treatment approach. Our study has shown that, the coronal subvolume MIP reconstruction method is more successful compared to the axial MPR and subtraction methods.…”

Background: The aim of this study was to compare conventional digital subtraction angiography (DSA) with the multi-planar reformation (MPR) and maximum intensity projection (MIP) reconstruction of servical magnetic resonance angiography (MRA) in terms of detecting supra-aortic artery stenoses.Methods: In the study, 21 patients who had underwent 3D MRA and conventional DSA were retrospectively assessed. Axial MPR, coronal MIP reconstruction and contrast enhanced 3D MRA subtraction images of a total of 333 artery segments were independently assessed by 2 separate radiologists. Conventional DSA results were accepted as gold standard results. The overall and individual Kappa values of all methods were calculated.Results: Results of the conventional DSA analysis indicated total occlusion in 9 (2.7%), severe stenosis in 16 (4.8%), moderate stenosis in 90 (27.1%), mild stenosis in 105 (31.5%) and no stenosis in 113 (33.9%) arteries. While the k values of all methods were high which demonstrated strong relationships with the DSA method; the coronal MIP reconstruction method was found to be superior to other methods. The 3D MRA subtraction method did not yield better results in any of the individual comparisons.Conclusions: Our results indicate that the coronal MIP reconstruction method has higher correlation with conventional DSA results compared to the other two methods and may be used as an accurate first-line diagnostic method for supra-aortic artery stenoses.

MR Angiography at 3 Tesla to Assess Proximal Internal Carotid Artery Stenoses: Contrast-Enhanced or 3D Time-of-Flight MR Angiography?

Abstract: Both 3D TOF-MRA and CE-MRA at 3 T are reliable tools for detecting high-grade proximal ICA stenoses (70-99 %). 3D TOF-MRA might misclassify pseudo-occlusions as complete occlusions. If there are no contraindications for CE-MRA, CE-MRA is recommended as primary MR imaging modality.
