RADIAL DCE-MRI FOR ASSESSMENT OF TUMOR VASCULAR RESPONSE

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。 DCE-MRI需要高时间采样率成像来评价造影剂进入的动力学 转化为肿瘤对于使用直线k空间采集的常规MR成像， 采集速度导致图像分辨率和体积覆盖的降低。使用平行 成像可以部分地引起这种情况，但是可以引入额外的成像伪影。径向MR采集 可用于提高时间数据采样率。使用KWIC处理保留了 以获得高分辨率图像。

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.
