Fig. 1From: New MR sequences in daily practice: susceptibility weighted imaging. A pictorial essayNormal subject. a SWI magnitude image. b SWI, minimal intensity projection (minIP; 10 mm) image: cortical and subependymal veins are well displayed. c SWI, phase map: the distinction between the pars reticulata (arrow) and compacta (asterisk) of the substantia nigra is enhanced compared with conventional fast SE and GE sequences. The outer margins of the red nucleus are also better displayed (see d for comparison). d T2-weighted axial imageBack to article page
