Black-blood steady-state magnetic resonance angiography

Published

Journal Article (Academic article)

This paper evaluates steady-state Magnetic Resonance Imaging as a method to generate images depicting flow with low signal intensity for a wide range of velocities. Sixty or twenty eight cross-sectional images with 0.7-1 mm in-plane resolution were obtained by 3-dimensional Fourier transformation of signals received from a 5-10cm thick coronal slab. Optimal acquisition parameters for in vivo imaging of the lower extremities were determined. Image processing was employed to generate angiographic displays of the vasculature from low signal intensity vessel segments depicted on the individual cross-sectional images. The black-blood steady-state method was also tested on two different phantoms with known flow profiles.
