腹部和盆腔脓肿的诊断和定位是困难的。作者统计了4000例腹部脓肿患者中有30％死亡,主要原因是延误诊断。未诊断出的肝脓肿常常致死。超声扫描仪可用来显示软组织的密度。脓肿常表现为内含不同量碎屑的囊肿,肝周围炎症反应也有助于其诊断。扫描技术的分辨力远胜于原先采用的bistable仪,从而提高了脓肿诊断和定位的准确度。 Abdominal and pelvic abscess diagnosis and positioning is difficult. The authors calculated that 30% of the 4000 abdomen abscess patients died, mainly due to delayed diagnosis. Undetected liver abscesses are often fatal. Ultrasound scanners can be used to show the density of soft tissue. Abscesses are often manifested as cysts containing different amounts of debris, and the inflammatory response around the liver is also helpful in their diagnosis. The resolution of the scanning technology is far better than the original bistable meter, thus improving the accuracy of abscess diagnosis and positioning.
