摘要目的研发一种新的MR胆胰管成像(MRCP)扫描方法:基于5%k空间预采样数据稀疏迭代重建屏气(BH)多翻转角三维快速自旋回波(BH SPARSE-SPACE),并将其与常规呼吸触发(RT SPACE)结果进行比较。材料与方法这项符合HIPAA的前瞻性研究获得伦理委员会批准。应用3 T设备对29例病人进行了常规RT SPACE及BH加速5%k空间数据采样SPACE扫描。两者空间分辨率和其他参数尽可
Abstract Objective To develop a new MR cholangiopancreatography (MRCP) scanning method based on the sparse iterative reconstruction of BH-SPARSE-SPACE based on pre-sampled data of 5% k space. It is compared to the results of conventional respiratory triggering (RT SPACE). Materials and Methods This HIPAA-compliant prospective study was approved by ethics committee. Twenty-nine patients underwent routine RT SPACE and BH accelerated 5% k spatial data sampling SPACE scans using the 3 T device. Both spatial resolution and other parameters as much as possible
