Fig. 2 —Schematic double oblique multiplanar reformation at coronal
level of spinal cord in 36-year-old woman shows course of artery of
Adamkiewicz and its feeding arteries with locations of diametric and
contrast-to-noise evaluations (1). All evaluated posterior branches of feeding
and neighboring segments were evaluated 5 mm distal to vascular bifurcation of
intercostal or lumbar artery (2). Radiculomedullary artery was uniformly
evaluated while passing through neuroforamen; great anterior radiculomedullary
artery was assessed in a base segment (3) characterized by horizontal
orientation of vascular cross section and in a hairpin segment (4) delineated
by a vertical vascular cross section. Measurements in anterior spinal artery
were performed 5 mm below hairpin junction (5).
