Abstract:
Objective To explore the difference between interval storage and continuous storage of dynamic imagines in contrast enhanced ultrasound (CEUS) quantitative analysis. Methods Two CEUS were performed for each of fifteen participants using interval storage and continuous storage of dynamic images. A number of parameters were analyzed including rising time (RT), time to peak (TTP), mean transit time (MTT), maximum intensity (IMAX), and area under the curve (AUC). The disk usage and time consumpation were also compared for analysis. Results There were no differences in RT, TTP, MTT, IMAX, AUC between the two groups (t=1.028, 1.012, 0.558, 0.223, 0.556, P=0.322, 0.329, 0.586, 0.826, 0.587). There was significantly positive correlations between them (r=0.989, 0.992, 0.867, 0.865, 0.947, all P<0.05). The disk usage in interval storage group was about 1/3 of that in contiunous storage group. And the interval storage method could saved 25-30 min in each case. Conclusion Interval storage is worthy for further clinical application on the groud of its disk usage sparing and less time consumpation without compromising the image quality for analysis.
