Susceptibility Weighted Imaging and MR Angiography

Magnetic resonance angiography (MRA) has undergone tremendous development since its inception (Nayler et al., J Comput Assist Tomogr 10:715–722, 1986; Nishimura et al., IEEE Trans Med Imaging 5:140–151, 1986; Haacke and Lenz, AJR Am J Roentgenol 148:1251–1258, 1987). To image the vessels in the brain at high fields clinically, there is no longer the need to use contrast agents thanks to the increased signal-to-noise at 3 T and the rapid …
