“…Black-blood (BB) imaging is used to complement the contrast-enhanced 3D gradient-echo (CE 3D GRE) imaging to detect BM, wherein variable refocusing flip angles combined with flow-sensitizing gradients are used, selectively suppressing moving blood while stationary tumor contrast remains visible 13 . These sequences can be useful in acquiring 3D brain data from BM patients and overcoming the disadvantages of the 3D magnetization-prepared rapid gradient echo (MPRAGE), which was originally commonly used for detecting BM 13 , 14 because of its high spatial resolution and low partial volume effects. Single-slab 3D turbo spin echo BB images with slab selective, variable excitation pulses, such as sampling perfection with application-optimized contrasts using different flip-angle evolution (SPACE), enable the acquisition of high-resolution 3D datasets with contrasts similar to those obtained from 2D T2-weighted, T1-weighted, proton density, and dark fluid protocols.…”

“…Through sensitizing the equilibrium magnetization to motion, iMSDE can effectively suppress the blood signal while also diminish motion artifacts. 22,23 Understanding the advantages and limitations of different DB techniques in T 2 mapping is important for optimizing T 2 mapping protocols and improving diagnostic capabilities. However, comparative studies of iMSDE and DIR are lacking.…”

“…Unlike DIR, which depends on multiple inversion pulses, iMSDE exploits the intrinsic motion of the myocardium to achieve DB imaging. Through sensitizing the equilibrium magnetization to motion, iMSDE can effectively suppress the blood signal while also diminish motion artifacts 22,23 …”
