Straight X-rays of 92 control patients with acute appendicitis and 92 control subjects were studied for radiographic abnormalities. Disturbance in intestinal gas pattern was the most common abnormality. Presence of a faecolith, free peritoneal fluid, scoliosis and a soft tissue mass were useful supporting signs. Loss of the properitoneal fat line and the right psoas outline were not reliable signs as they occurred with equal frequency in both groups.
对92例急性阑尾炎患者及92名对照者进行了X线平片检查，以观察影像学异常情况。肠气模式紊乱是最常见的异常表现。粪石、游离腹腔积液、脊柱侧凸及软组织肿块的存在是有用的辅助征象。腹膜外脂肪线和右侧腰大肌轮廓消失并非可靠征象，因为两组出现的频率相同。
