473-125 | Color M-mode Ultrasound to Assess Carotid Arteries: A Feasibility Study-JVU 473-125

JVU 473-125

Pdf Summary

This study investigated the feasibility of using color M-mode ultrasound to evaluate age-related changes in the carotid arteries. The researchers performed color M-mode ultrasound on the distal common carotid artery in 62 adults in three age groups: young adults (20-44 years), middle-aged adults (45-64 years), and seniors (≥65 years). They quantified the total, red, green, and blue (RGB) pixels in systole and diastole using image processing software. The distensibility of the carotid artery was calculated based on the systolic and diastolic diameters, and the pixel counts were analyzed to assess changes in blood flow.<br /><br />The findings showed that there were significant differences in carotid artery distensibility among the three age groups, with a decrease in distensibility observed in the senior group. The RGB pixel counts in systole were also significantly different among the age groups, indicating changes in blood flow. However, there were no significant differences in the diastolic pixel counts. Intraobserver repeatability and interobserver reproducibility were excellent, indicating the reliability of the measurements.<br /><br />The study demonstrates that color M-mode ultrasound is feasible for assessing age-related changes in the carotid arteries. It provides a quantitative measurement of dynamic function and can be used to evaluate vascular changes associated with atherosclerotic cardiovascular disease. The use of color M-mode ultrasound offers a non-invasive, cost-effective, and portable method for assessing arterial compliance and blood flow in clinical settings. Further research with larger sample sizes and a diverse range of participants is needed to validate and expand on these findings.
