目的:探讨点压摄影技术在乳腺疾病诊断中的应用价值。方法:对131例乳腺常规摄影所见的可疑病变用点压摄影技术检查后经病理验证,将两种检查方法做对照性研究,分别计算出两种方法对诊断乳腺疾病的特异度、灵敏度、似然比。结果:平片摄影和点压摄影技术对病灶的显示灵敏度分别为87.5%和92.5%,特异度分别为82.3%和86.3%,经过局部点压的图像,乳腺组织结构及病灶的清晰度增加,特别是病灶边缘显示更好。结论:点压摄影技术对乳腺疾病的诊断优于常规片,特别是对团状致密影、细小钙化、致密型乳腺病变性质的评估有重要的价值。
Objective: To investigate the value of point-pressure photography in the diagnosis of breast diseases. Methods: Thirty-one cases of suspected breast lesions were examined by point-pressure photography, and the two methods were compared. The two methods were used to calculate the specificity, sensitivity, Likelihood ratio. Results: The sensitivity of plain photography and point-press photography to the lesions were 87.5% and 92.5% respectively, the specificity were 82.3% and 86.3% respectively. After local point-pressure imaging, the clarity of the breast tissue structure and lesion increased, Especially the edge of the lesion shows better. Conclusion: Point-and-shoot photography is superior to conventional films in the diagnosis of breast diseases, especially for the evaluation of the characteristics of dense, small calcification and dense breast lesions.
