Fig. 6B —57-year-old man with left renal artery stent referred for
imaging of renal and lower extremity arteries. Three-dimensional
gadolinium-enhanced MR angiography was performed at 1.5 T. Imaging parameters
are bandwidth, 31.25 MHz/s; TR/TE, 8.8/2.9; slice thickness, 1.3 mm (A)
and bandwidth, 62.5 MHz/s; 5.9/1.4; slice thickness, 0.8 mm (B).
Metallic susceptibility artifact from stent (arrow) is less when
using wider bandwidth with shorter TE in comparison with narrower bandwidth
and longer TE.
