Reducing Noise Induced by Cardiac Pulsatility in Brain Maps of R 2 * and Magnetic Susceptibility Using Tailored k‐space Sampling

Key Result

Synchronization of data acquisition with the cardiac cycle did not reduce the level of cardiac-induced noise in brain maps of R2* and magnetic susceptibility.

Key Points

• This research aims to address and reduce the noise incurred from cardiac pulsatility in brain imaging maps.
• Tailored k-space sampling was implemented to optimize data acquisition.
• Synchronization with the cardiac cycle was tested as a noise reduction strategy.
• No significant reduction in cardiac-induced noise was observed despite synchronization with the cardiac cycle.
