A technique that can offer improved ultrasonic visualization of the pancreas is reported and evaluated. One hundred subjects were scanned in an erect sitting position with fluid-filled stomachs ("erect gastric window" technique). Conventional supine scans were initially performed in all cases; oblique, semierect, decubitus, prone, and standing positions with and without fluid-filled stomach were also evaluated. Compared with supine scans, the "erect gastric window" technique, occasionally supplemented by semierect, oblique, or decubitus views, provided significantly improved visualization of the pancreas in 93% of subjects. The nonvisualization rate was reduced from 19% to 1%.
报道并评估了一种可改善胰腺超声显像的技术。对100名受试者采用胃内充盈液体的直立坐姿进行扫描（“直立胃窗”技术）。所有病例均首先进行常规仰卧位扫描；还评估了有或无胃内充盈液体情况下的斜位、半直立位、侧卧位、俯卧位和站立位。与仰卧位扫描相比，“直立胃窗”技术（偶尔辅以半直立位、斜位或侧卧位视图）使93%的受试者胰腺显像显著改善。胰腺未显影率从19%降至1%。
