Accuracy of carotid plaque detection and intima–media thickness measurement with ultrasonography in routine clinical practice

Intima‐medial thickness homogeneity in the common carotid artery: Measurement method and preliminary clinical study

“…Both the left and the right carotid arteries were scanned in the transverse and longitudinal planes at standard insonation angles. 5, 8, 10 The probe was securely positioned, and the sonographic beam was maintained perpendicular to the vessel wall. The probe was then moved downward from the bifurcation toward the origin of the CCA.…”

“…Controversy exists surrounding whether a local IMT of >1 mm or 1–1.5 mm should be considered as evidence of plaque. 4, 10, 12 In the present study, we defined IMT ≥1 mm as thickening and focal IMT ≥1.2 mm as plaque.…”

“…4, 5, 7–9 Most clinicians accept an IMT <1.0 mm as normal, although considerable debate exists in this regard. 4, 10–12 As carotid IMT depends on gender and ethnicity and increases with age, its interpretation relies on reference values obtained in cohorts of normal subjects. 6, 7 Moreover, atherosclerosis is a continuously developing process that tends to be exacerbated by exposure to environmental factors.…”

Association of the thickness of carotid intima-media complex and ancle brachial index with coronary disease severity

“…A high level of accuracy for detecting plaques (sensitivity 78.5%; specificity 93.6%) was achieved. Identifying abnormal IMT had lower sensitivity but adequate specificity of 46.7% and 87.6%, respectively [18].…”

Effectiveness of Screening Postmenopausal Women for Cardiovascular Diseases: A Population Based, Prospective Parallel Cohort Study

“…The chosen diagnostic screening tools had an acceptable diagnostic accuracy; US for AAA has a sensitivity of 97.5% and a specificity of 98.9%; 24 PAD based on an ankle brachial pressure index 0.90 has a pooled sensitivity of 75% and a specificity of 86%; 25 for the presence of CP, a sensitivity of 78.5% and a specificity of 93.6% have been reported; 26 office blood pressure 140/90 mmHg has a sensitivity of 74.6% and a specificity of 74.6%; 27 and traditional pulse palpation for AF has a pooled sensitivity of 92% and a pooled specificity of 82%. 28 Although the overall screening attendance rate (74.3%) was acceptable, selection bias may be present.…”
