- Real-time blood flow imaging using autocalibrated spiral sensitivity encodingReza Nezafat
Department of Biomedical Engineering, Johns Hopkins University, Baltimore, Maryland 20892 1061, USA
Magn Reson Med 54:1557-61. 2005..Real-time experiments were performed to measure blood velocity in the ascending aorta and aortic valve, and during a Valsalva maneuver. The results demonstrate the potential of this technique for real-time flow imaging...
- Partial field-of-view spiral phase-contrast imaging using complex difference processingReza Nezafat
Department of Biomedical Engineering, Johns Hopkins University, Baltimore, Maryland, USA
Magn Reson Med 56:676-80. 2006..Experiments in a flow phantom and volunteers showed that the flow estimates obtained by pFOV spiral motion encoding are in good agreement with the estimates reconstructed using complex difference processing...
- Coronary magnetic resonance vein imaging: imaging contrast, sequence, and timingReza Nezafat
Department of Medicine Cardiovascular Division, Beth Israel Deaconess Medical Center, Boston, Massachusetts 02215, USA
Magn Reson Med 58:1196-206. 2007..Both GRE and SSFP were viable imaging sequences, although GRE provided more robust results with better contrast. Imaging during the end-systolic quiescent period was preferable as it coincided with the maximum size of the coronary veins...
