초록

Abdominal ultrasound images with or without compression of the transducers, beforeand after endoscopy, were evaluate SNR and CNR which showing good images of abdominalorgans (centered on the pancreas) and the effect of reducing stomach, duodenum, and intestinalgas artifacts. Statistical analysis was performed using the non-parametric krukal-Wallis testcomparisons between the presence or absence of compression and before and after endoscopy. Thestructural model of the triple batch method with the different number of experimenters was usedfor expected factors that will affect the response value (with or without compression, SNR or CNR,group). Between difference before and after endoscopy and SNR, CNR intergroup interactionswere statistically significant. Scheffe’s post test was used to compare the mean difference betweengroups, the response value of overweight was higher than that of the control group (phantom),and there was no difference between the other groups in the control group. CNR and SNR andintergroup interactions are similar to intergroup effect of overweight (NO) before endoscopyin responses to CNR and SNR were significant differences and other patients showed similarresults to phantom. Before and after endoscopy of with or without compression, there was nodifference between before and after endoscopy. The SNR and CNR values were higher than thoseof compression stress. Therefore it would considered necessary to apply pressure to improve thequality of the abdominal ultrasound image.
