Experience with rotator cuff sonography in 106 patients was analyzed to identify the causes of scan misinterpretation. Possible interpretive errors may be classified into four categories: those from failure to recognize normal anatomy, those caused by soft-tissue abnormalities, those caused by bony abnormalities, and those caused by technical limitations of the study. Errors in recognition of normal anatomy are easily overcome by experience and comparison to the normal, contralateral rotator cuff. Errors resulting from soft-tissue abnormalities were seen in two patients with calcific tendinitis simulating rotator cuff tears. Problems in interpretation resulting from fractures in two patients and inferior glenohumeral subluxation in two other patients could have been avoided by review of the plain films before performing sonography. The major technical limitation of the study arises from the inability to image the rotator cuff beneath the acromion. Fortunately, rotator cuff tears are rarely isolated in this location, and passive maneuvers often allow otherwise hidden parts of the cuff to be imaged.
对106例患者的肩袖超声检查经验进行分析，以确定扫描误判的原因。可能的解释错误可分为四类：因未能识别正常解剖结构导致的错误、由软组织异常引起的错误、由骨骼异常引起的错误以及由检查的技术局限性导致的错误。通过经验以及与对侧正常肩袖进行比较，正常解剖结构识别方面的错误很容易克服。两名患有模拟肩袖撕裂的钙化性肌腱炎患者出现了由软组织异常导致的错误。另外两名患者因骨折以及另外两名患者因肩肱关节下脱位导致的判读问题，可通过在进行超声检查前查看X线平片来避免。该检查的主要技术局限性源于无法对肩峰下方的肩袖进行成像。幸运的是，肩袖撕裂很少孤立发生在这个部位，并且被动手法操作通常能使原本隐藏的肩袖部分得以成像。
