Outer Volume Suppression for Three Different Steady State Sequences Used in Percutaneous Interventions

Jaane Rauschenberg¹, Patrik Zamecnik², Wolfhard Semmler¹, Michael Bock¹

Outer volume suppression (OVS) is performed in steady state sequences to restrict the field of view and thus, to accelerate the image acquisition. Without destroying the steady state, OVS is integrated in three different pulse sequences (FLASH, PSIF, trueFISP) which provide T1, T2-like and T2/T1 image contrast. With a 12.5% FOV restriction an update rate of 5 images/s could be achieved.
