Low Attenuation Plaque

Background The capabilities of coronary computed tomography angiography (CCTA) have advanced significantly in the past decade. Its capacity to detect stenotic coronary arteries safely and consistently has led to a marked decline in invasive diagnostic angiography. However, CCTA can do much more than identify coronary artery stenoses. Method This review discusses applications of CCTA beyond coronary stenosis assessment, focusing in particular on the visual and quantitative analysis of atherosclerotic plaque. Results Established signs of visually assessed high-risk plaque on CT include positive remodeling, low-attenuation plaque, spotty calcification, and the napkin-ring sign, which correlate with the histological thin-cap fibroatheroma. Recently, quantification of plaque subtypes has further improved the assessment of coronary plaque on CT. Quantitatively assessed low-attenuation plaque, which correlates with the necrotic core of the thin-cap fibroatheroma, has demonstrated superiority over stenosis severity and coronary calcium score in predicting subsequent myocardial infarction. Current research aims to use radiomic and machine learning methods to further improve our understanding of high-risk atherosclerotic plaque subtypes identified on CCTA. Conclusion Despite rapid technological advances in the field of coronary computed tomography angiography, there remains a significant lag in routine clinical practice where use is often limited to lumenography. We summarize some of the most promising techniques that significantly improve the diagnostic and prognostic potential of CCTA. Key Points:  Citation Format

Significant Difference

Objective: To clarify the differences in assessing the course of the lingual artery between lingual artery computed tomography angiography (CTA) and ultrasound (US). Methods: Twenty-six OSA patients were included in this study and accomplished lingual artery CTA and US, respectively. The differences in the depths of the lingual arteries and the distances between the bilateral lingual arteries on 3 measurement levels based on lingual artery CTA and US were compared. Results: The depths of the lingual arteries on 3 measurement levels by CTA were deeper than those by US ( P < .01). There was no significant difference in the distances between bilateral lingual arteries on 3 measurement levels between CTA and US ( P > .05). Conclusions: The parameters of lingual artery measured by lingual artery US were similar to or smaller than those measured by lingual artery CTA. Like lingual artery CTA, lingual artery US could be used as an effective method to ensure the safety of the operation.
