Phase enhancement for time-of-flight and flow-sensitive black-blood MR angiography
Autor: Masato Ikedo, Shuhei Takemoto, Tokunori Kimura
Publikováno v: Magnetic Resonance in Medicine. 66:437-447
A magnitude-based MR angiography method of standard time-of-flight (TOF) employing a three-dimensional gradient-echo sequence with flow rephasing is widely used. A recently proposed flow-sensitive black-blood (FSBB) method combining three-dimensional
