ABSTRACT:
T*.sub.2 contrast in images reconstructed from fast NMR pulse sequences is improved by increasing the gradient recalled echo time TE. The pulse repetition time TR is minimized to maintain high temporal resolution by asymmetrically acquiring the echo signal with its peak disposed bear the end of the acquisition window.
