Abstract

New, rapid two‐ and three‐dimensional imaging sequences based on steady‐state gradient echoes and projection‐reconstruction (PR) techniques are proposed. Quantitative studies show that fast PR sequences and classical, fast gradient‐echo Fourier transform sequences lead to identical contrasts. In order to minimize inhomogeneity effects, a particular focus has been placed on echo‐time reduction. The use of a weighting window permits one to acquire severely truncated echoes; partial k‐space scanning may be considered.
