目标。“搜索满意”描述了一种情况，即一种x线摄影异常的检测干扰了其他异常的检测。这一现象尚未被研究用于骨骼x线片的解释。我们确定是否满意搜索发生在解释常规x线片的肌肉骨骼系统。研究对象和方法：12名来自放射科的志愿者（10名住院医生和2名工作人员）和13名来自骨科的志愿者（所有住院医生）按随机顺序排列，其中15例出现一种异常，15例出现两种或三种异常。有多种表现的病例共包含19个异常。所有病例均选自急诊科。志愿者得到三个分数，反映他们在单个发现病例中发现异常的能力，在多个发现病例中发现至少一个异常的能力，以及在多个异常病例中发现额外的发现的能力。比较采用卡方检验和耶茨校正。并进行方差分析和Bonferroni调整。在单一发现病例中，平均检出率为11.25；在15例多重发现病例中，单个发现的平均检出率为11.72。差异无统计学意义。第二、三次异常检出率在多发病例中较低，平均为6.12 （p < 0.01）。一个显著的满意的搜索效果发生，并在解释的x线片的肌肉骨骼系统的操作。
OBJECTIVE. "Satisfaction of search" describes a situation in which the detection of one radiographic abnormality interferes with that of others. This phenomenon has not been investigated for the interpretation of skeletal radiographs. We determined whether satisfaction of search occurs in the interpretation of conventional radiographs of the musculoskeletal system.SUBJECTS AND METHODS, Twelve volunteers from radiology (10 residents and two staff members) and 13 volunteers from orthopedic surgery (all residents) were shown in random order 15 cases in which one abnormality was present and 15 cases in which either two or three abnormalities were present. The cases with multiple findings contained a total of 19 abnormalities. All cases were selected from the emergency department. The volunteers received three scores reflecting their ability to detect abnormalities on a single-finding case, at least one abnormality on a multiple-finding case, and additional findings in cases with multiple abnormalities. The scores were compared using the chi-square test with Yates correction. Analysis of variance and Bonferroni adjustment were also performed.RESULTS. Among the cases with single findings, detection rates averaged 11.25; for the 15 multiple-finding cases, the detection rate for one finding averaged 11.72. The difference was nor statistically significant. Detection rates for the second and third abnormalities in the multiple-finding cases were significantly lower, averaging 6.12 (p < 0.01).CONCLUSION. A significant satisfaction of search effect occurred and was operative in the interpretation of radiographs of the musculoskeletal system.
