2D RF Pulses with Rotating Read Out Direction for Increased FOV with Elevated Central SNR

Andre de Oliveira¹, Tobias K. Block¹, Stephan Kannengiesser¹

In MRI exams, focus is often given to a specific pathologic region (eg.: prostate, liver, brain) and in most cases the field of view (FOV) is centred at the region to be analysed. Here we propose a a new acquisition technique where 2D RF pulses to are employed and the RO direction is rotated for each individual average, allowing image acquisition with high central SNR (the same SNR as acquired with the actual protocols using 2D RF pulses) and increased FOV.
