  • Title: The impact of navigator timing parameters and navigator spatial resolution on 3D coronary magnetic resonance angiography.
    Author: Spuentrup E, Stuber M, Botnar RM, Manning WJ.
    Journal: J Magn Reson Imaging; 2001 Sep; 14(3):311-8. PubMed ID: 11536409.
    Abstract:
    The impact of navigator spatial resolution and navigator evaluation time on image quality in free-breathing navigator-gated 3D coronary magnetic resonance angiography (MRA), including real-time motion correction, was investigated in a moving phantom. Objective image quality parameters signal-to-noise ratio (SNR) and vessel sharpness were compared. It was found that for improved mage quality a short navigator evaluation time is of crucial importance. Navigator spatial resolution showed minimal influence on image quality.
