It is a combination of time-of-flight and spin-phase effects usually seen in spin-echo techniques (such as T2-weighted images) 1. in MRI, absence of signal from blood whose activated protons leave a bodily area before the magnetization is measured. 2. In MRI, any loss of signal caused by combined turbulence and intravoxel dephasing. flow_void.txt Last modified: 2024/06/07 02:54by 127.0.0.1
