In a prospective study of 132 men suspected to have liver disease, ultrasound defined ascites in 62. Patients with minimal ascites were most likely to have subtle fluid collections around the liver. When this minimal ascites was confined superior to the liver, real-time sector units were unable to detect it with medium-focus transducers. A right lateral decubitus position (right side down) for detection of small amounts of fluid was superfluous.
在一项针对132名疑似患有肝脏疾病男性的前瞻性研究中，超声检查发现62人存在腹水。腹水极少的患者最有可能在肝脏周围有细微的液体积聚。当这种极少的腹水局限于肝脏上方时，实时扇形超声仪使用中聚焦探头无法检测到。右侧卧位（右侧向下）用于检测少量液体是多余的。
