Conjugation and hybrid MR imaging.

摘要: PURPOSE: To evaluate the use of conjugation with hybrid magnetic resonance imaging techniques in order to reduce artifacts from inconsistencies introduced by T2 decay. MATERIALS AND METHODS: Two phantoms containing either oil or water were used study edge spread function (ESF) and signal-to-noise ratio (S/N) for three acquisition strategies (low pass, high ramp) which a full set was acquired partial conjugation. RESULTS: With half echoes providing coverage same amount k space, signal reduced factor at least e. Conjugation improved ESF degradation, sequence efficiency increased over 50%, compensated loss S/N. CONCLUSION: The time saved can be nearly double number sections given repetition (TR) obtain two simultaneous instead one, reduction artifacts. Alternatively, halved TR ...
