description Publicationkeyboard_double_arrow_right Article , Journal 2013 United Kingdom, AustraliaPublisher:Wiley Jenni Schulz; David G. Norris; David G. Norris; David G. Norris; Rasim Boyacioğlu; Peter J. Koopmans; Peter J. Koopmans; Peter J. Koopmans; Markus Barth; Markus Barth;PurposeTo explore the use of PINS radiofrequency (RF) pulses to reduce RF power deposition in multiband/simultaneous multislice imaging with the RARE/turbo spin echo (TSE) sequence at 3T and 7T.MethodsA PINS‐TSE sequence was implemented and combined with blipped CAIPI to improve the reconstruction of superposed slices. Whole brain imaging of healthy volunteers was performed at both 3T and 7T using a 32‐channel coil for signal reception.ResultsA considerable reduction in power deposition was achieved compared with a standard sequence of the manufacturer. At 3T, the reduction in specific absorption rate (SAR) made short pulse repetition times (TRs) possible, however, in order to obtain a good T2 contrast, it is advisable to maintain TR while extending the echo train length. At 7T, whole brain coverage with a spatial resolution of 1 × 1 × 2 mm3 was achieved in an acquisition time of 150 s. Furthermore, it could be shown that pulse sequences that use PINS pulses do not suffer from having additional magnetization transfer contrast.ConclusionPINS RF pulses combined with multiband imaging reduce SAR sufficiently to enable routine TSE imaging at 7T within clinically acceptable acquisition times. In general, the combination of multiband imaging with PINS RF pulses represents a method to reduce total RF power deposition. Magn Reson Med 71:44–49, 2014. © 2013 Wiley Periodicals, Inc.
