Background Currently the most widely accepted predictor of stroke risk in patients with carotid atherosclerosis is the degree of stenoses. Plaque echogenicity on ultrasound imaging (US) and intraplaque neovascularization (IPNV) are becoming recognized as factors of plaque vulnerability. Aim of the study was to investigate the correlation between the echogenicity of the carotid atherosclerosis by standard US and the degree of IPNV by contrast enhanced US (CEUS). Methods We recruited 45 consecutive subjects with an asymptomatic ≥ 50% carotid artery stenoses. Carotid plaque echogenicity at standard US was visually graded according to Gray-Weale classification (GW) and measured by the grayscale median (GSM), a semi-automated measurement performed by Adobe Photoshop©. On CEUS imaging IPNV was graded by different point scales according to the visual appearance of contrast within the plaque as follows: CEUS_A (1 = absent; 2 = present); CEUS_B (increasing IPNV from 1 to 3); and CEUS_C (increasing IPNV from 0 to 3). Results The correlation between echogenicity by GW and IPNV grading was as follows: CEUS_B (− 0.130 p.423), CEUS_C (− 0.108, p.509), CEUS_A (0.021, p.897). The correlation between echogenicity by GSM measurement and IPNV was as follows: using a CEUS_A (− 0.125, p.444), CEUS_C (− 0.021, p.897) (0.005, p.977). No correlation was found statistically significant. Conclusion Our results display that there is no significant correlation between plaque echogenicity and IPNV. The small sample number and the multifaceted pathophysiology of the atherosclerotic plaque may explain the absence of statistically significantly correlation. Curtailing vulnerability explanation to either IPNV or echolucency may be misleading. © 2016 Elsevier Ireland Ltd

Here we provide the correlation among different carotid ultrasound (US) variables to assess echogenicity n standard carotid US and to assess intraplaque neovascularization on contrast enhanced US. We recruited 45 consecutive subjects with an asymptomatic50% carotid artery stenosis. Carotid plaque echogenicity at standard US was visually graded according to Gray-Weale classification (GW) and measured by the greyscale median (GSM), a semi-automated computerized measurement performed by Adobe Photoshop
