Zusammenfassung
Purpose: Due to their insensitivty to susceptibility effects Turbo Spin-echo (TSE)-based sequences appear to be very attractive for high field applications, where susceptibility effects can impair the image quality. However their application at 3T interfere with high RF power deposition (exceed the specific absorption rate SAR limits for patient safety), especially single shot TSE sequences suffer from RF-deposition. It is well known that the SAR reduction can be obtained by using parallel imaging (SENSE) and half Fourier, which decrease the RF-deposition by echo train shortening. Nevertheless, very often a shor…
