The first application of a double coil for routine MR mammography is described: by this method it is possible to examine both breasts simultaneously. This is important in order to halve the time of the examination and to allow comparison of the two breasts during dynamic contrast studies. The reduction in signal-to-noise ratio, compared with a single coil and flow artifacts of the heart do not interfere with diagnosis. The axillary region is better shown than with a single coil. Examination of 22 patients with subsequent histological control has shown that the information about signal increase after the injection of Gd-DTPA obtained from single coil can be applied equally to the double coil.
通过这种方法可以同时检查双侧乳房。这对于将检查时间减半以及在动态对比研究中对双侧乳房进行比较非常重要。与单线圈相比，信噪比有所降低，但心脏的血流伪影并不影响诊断。腋窝区域的显示比单线圈更好。对22例患者进行检查并随后进行组织学对照，结果表明，从单线圈获得的注射钆喷酸葡胺后信号增强的信息同样适用于双线圈。
