摘要
目的：评价ＣＴ在乳癌腋窝淋巴结诊断中的价值。材料与方法：２０例乳癌患者在术前做了ＣＴ扫描，并和病理结果作了比较，腋窝淋巴结短径≥０．５ｃｍ认为是异常。结果：ＣＴ检出１１例有腋窝淋巴结增大，病理均证实为转移；４例病理为转移而ＣＴ却阴性；临床检查时仅１０例可扪及腋窝淋巴结。ＣＴ的真阳性率为７３％，假阴性率为２７％，敏感性１００％。结论：虽然ＣＴ较优于临床检查，但仍不是一种术前预计腋窝淋巴结是否受累的准确方法，其主要原因是假阴性率较高。
To determine the CT value of axillary lymph nodes(LNS) in patients with breast cancer.Materials and Methods:20 patients of breast cancer were scanned preoperatively,and compared with the pathololgic results.Axillary LNS measuring≥0.5cm were considered abnormal.Results:CT have detected enlarged LNS in 11 patients and all were confirmed metastasis by pathology.4 patients the pathologic result were metastasis,but CT were negative.On physical examination only 10 patients could palpate the axillary LNS.The true positive rate of CT was 73%,the false negative rate was 27%,and the sensitivity was 100%.Conclusion:Although superior to physical examination,CT was not an accurate predictor of axillary LNS involvement,because of the high false negative rate.
