摘要：
A dynamic MRA study is performed using a 3D fast gradient recalled echo pulse sequence. A signal strength indicator for each acquired k-space data set is calculated from the k-space raw data and these indicator values are employed to produce a contrast curve. This contract curve is used to select data for use in forming a CONTRAST k-space data set and a MASK k-space data set. The MASK is subtracted from the CONTRAST data set and the result is used to reconstruct an image.
