Two different instruments for nonpalpable breast lesion localization, with different patient position (prone and sitting), were evaluated in precision performances by measuring the mean needle deviation on X and Y axes in 150 and 100 examinations, respectively. Both instruments yielded precise information: some drawbacks were observed with the stereotaxic instrument fitted to the plain mammographic unit, due to imperfect fixation in the sitting position of the patient. The development of special seats could obviate the problem, thus allowing a further improvement in the performance of this kind of instruments.
对两种用于不可触及乳腺病变定位的不同仪器进行了评估，患者采用不同体位（俯卧位和坐位），分别通过在150例和100例检查中测量X轴和Y轴上的平均针偏移来评估其精确性能。两种仪器均能提供精确信息：安装在普通乳腺X线摄影设备上的立体定位仪器存在一些缺点，因为患者坐位时固定不完美。开发特殊座椅可避免该问题，从而使这类仪器的性能得到进一步改善。
