3D BILATERAL BREAST IMAGING USING SLICE DIRECTION ARC PARALLEL IMAGING

该子项目是利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得主要资金， 因此可以在其他CRISP条目中表示。列出的机构是 中心，不一定是研究者的机构。 乳腺动态对比增强（DCE）MR成像已被证明在癌症检测中具有高灵敏度。 因为典型的DCE协议需要时间序列的图像来提供关于造影剂摄取的信息，所以由于时间限制，使用传统的扫描技术可以将图像覆盖范围限制到单个乳房。 然而，双侧乳腺成像的优势正在得到更多的认可。 除了单次造影剂增强检查的经济效益外，双侧成像在单独进行乳腺检查时消除了雌激素水平依赖的造影剂摄取。 我们机构的乳腺成像方案包括高分辨率矢状面3D脂肪抑制研究，以提供诊断解剖数据。 我们已经修改了该采集，通过使用自动校准的并行成像来执行双侧成像。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Dynamic Contrast-Enhanced (DCE) MR imaging of the breast has been shown to provide high sensitivity in the detection of cancer. Because the typical DCE protocol requires a time series of images to provide information on contrast uptake, the use of traditional scanning techniques can limit image coverage to a single breast because of time constraints. However, the advantages of bilateral breast imaging are receiving greater recognition. In addition to the economic benefits of a single contrast-enhanced exam, bilateral imaging eliminates estrogen-level dependent contrast uptake when separate breast exams are performed. The breast imaging protocol at our institution includes a high-resolution sagittal 3D fat-suppressed study to provide anatomic data for diagnosis. We have modified this acquisition to perform bilateral imaging through the use of autocalibrated parallel imaging.
