To this end, a pilot study documenting contrast\u2010enhanced vascularity of the median nerve was conducted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients undergoing contrast\u2010enhanced transthoracic echocardiography were recruited for this study (n = 24). During echocardiography, a simultaneous contrast\u2010enhanced sonographic examination of the median nerve was conducted. The study and study protocol were built from preclinical evidence. Image analysis was based on the power Doppler pixel intensity within a defined region of interest to obtain quantitative data representing the average pixel intensity, maximum pixel intensity, and power Doppler pixel dot count. Semiquantitative data representing the power Doppler dot count grading were also obtained.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Spearman correlations between analytical methods showed strong positive, statistically significant (<jats:italic>P<\/jats:italic>&lt; .05) correlations between the average pixel intensity and maximum pixel intensity and between the power Doppler dot count and dot count grading. Statistically significant increases in the average pixel intensity and power Doppler dot count were seen at all but 1 time point throughout the contrast\u2010enhanced sonographic examination when compared to precontrast administration. Statistically significant increases in the maximum pixel intensity were seen at all but 4 time points.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>These pilot results represent early evidence that contrast\u2010enhanced sonography can be used to image median nerve vascularity.
