Abstract

Abdominal ultrasound images with or without compression of the transducers, before and after endoscopy, were evaluate SNR and CNR which showing good images of abdominal organs (centered on the pancreas) and the effect of reducing stomach, duodenum, and intestinal gas artifacts. Statistical analysis was performed using the non-parametric krukal-Wallis test comparisons between the presence or absence of compression and before and after endoscopy. The structural model of the triple batch method with the different number of experimenters was used for 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 interactions were statistically significant. Scheffe's post test was used to compare the mean difference between groups, 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 and intergroup interactions are similar to intergroup effect of overweight (NO) before endoscopy in responses to CNR and SNR were significant differences and other patients showed similar results to phantom. Before and after endoscopy of with or without compression, there was no difference between before and after endoscopy. The SNR and CNR values were higher than those of compression stress. Therefore it would considered necessary to apply pressure to improve the quality of the abdominal ultrasound image.
