Signal heterogeneity in contrast-enhanced echocardiographic imaging despite uniform concentration of the contrast agent

Signal heterogeneity in contrast-enhanced echocardiographic imaging despite uniform concentration of the contrast agent

To quantify the heterogeneity of contrast enhancement inside left ventricular (LV) cavity, 10 patients were studied by harmonic intermittent power Doppler following venous echo contrast administration. Regions of interest were drawn in the LV cavity along the main axis and transversally to derive ti...

Zusammenfassung:To quantify the heterogeneity of contrast enhancement inside left ventricular (LV) cavity, 10 patients were studied by harmonic intermittent power Doppler following venous echo contrast administration. Regions of interest were drawn in the LV cavity along the main axis and transversally to derive time-intensity curves. Signal intensity at plateau (A) significantly decreased along LV longitudinal axis: from apex (48/spl plusmn/6 dB), to center (41/spl plusmn/7) and base (31/spl plusmn/9 dB, p
