RADIAL DCE-MRI FOR ASSESSMENT OF TUMOR VASCULAR RESPONSE

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 DCE-MRI需要高时间采样率成像来评估对比剂进入的动力学 变成了肿瘤。在使用直线k空间采集的传统MR成像中， 采集速度会导致图像分辨率和体积覆盖率降低。并列的使用 成像可以部分地开始这种情况，但可能会引入额外的成像伪影。径向MR采集 可用于提高时态数据采样率。使用KWIC处理保留了这样的能力 以获得高分辨率的图像。

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. DCE-MRI requires high temporal sampling rate imaging for evaluation of the kinetics of contrast entry into tumors. With conventional MR imaging using rectilinear k-space acquisition, increases in acquisition speed result in decreases in image resolution and volume coverage. The use of parallel imaging can onset this partially, but can introduce additional imaging artifacts. Radial MR acquisition can be used to improve temporal data sampling rate. The use of KWIC processing retains the ability to obtain high-resolution images.
