In the overall effort to increase the diagnostic efficacy of MRI as an adjunctive technique in the assessment of breast lesions and their staging, it is proposed (1) to demonstrate the feasibility of sequential parallel image acquisition (SPIA) techniques as a method to produce high resolution images of the breasts and axillary lymph nodes in reduced total scantime, (2) to design local coils to provide fat suppression, chemical shift, and contrast optimization techniques, and to increase signal-to-noise ratio in each region of interest and improve resolution, and (3) to optimize patient positioning procedures and compatible variations in coil design to account for differences from one patient to another and to enhance patient comfort and acceptance.

在提高MRI诊断AS疗效的总体努力中 一种辅助技术在乳腺病变评估中的应用 他们的阶段，建议(1)论证 序列并行图像采集(SPIA)技术 方法以产生高分辨率的乳房图像和 减少腋窝淋巴结的总扫描时间，(2)局部设计 提供脂肪抑制、化学位移和对比度的线圈 优化技术，并提高信噪比在 提高每个感兴趣区域的分辨率，以及(3)优化 患者定位程序和线圈的兼容变化 设计以考虑不同患者之间的差异，并 以提高患者的舒适度和接受度。
