Body Imaging at 3T: Lower SAR yields Improved Coverage with VERSE and Modulated Angle Refocusing Trains
نویسندگان
چکیده
To meet the challenge of providing adequate coverage at high field strength, a combination of two complementary methods is proposed: reshaped waveforms with the VERSE technique and a modulated angle refocusing train. It was hypothesized that pulses can be reshaped and flip angles can be modulated such that power is cut in half and thus coverage doubled. Volunteer experiments at 3T using an SSFSE sequence in the abdomen demonstrate a power reduction of 50% with unchanged contrast and SNR and improved resolution.

Reduction in Artifacts in the Liver at 3T Using a 3D T2-Weighted Variable Flip-Angle Sequence (SPACE)
Introduction: 3T MRI systems provide an inherent increase in SNR that can be used for gains in spatial and/or temporal resolution. However, a limitation of imaging at 3T is an increase in specific absorption rate (SAR), particularly in sequences with large flip angles and many refocusing pulses, as occurs with many 180o refocusing pulses of a turbo spin echo sequence. A recently developed seque...

Background Non-contrast Fresh Blood Imaging (FBI) scan time can be greatly reduced using variable TR for imaging the peripheral artery without contrast infusion, in which each slice encoding (SE) and the followed echo train are played in a variable TR (vTR) (TR=n*RR) pattern. In vTR FBI, the lower limit of TR depends on the length and timing of data acquisition, and it is also limited by SAR, w...
متن کاملReduced SAR with BASE Sequence at 7 Tesla
Introduction: To reduce measurement time, sequences are required which either significantly reduce the repetition time or acquire several echoes within each excitation. Among those the Turbo Spin Echo (TSE) is widely used today on clinical scanners at typical field strength of 1.5T to 3T. The step towards 7T provides a significantly higher MR signal potentially allowing for decreased scan time ...
متن کاملRobust diffusion-weighted imaging using split-blade PROPELLER and LRX phase modulation
Diffusion weighted (DW) brain image plays an important role in the diagnosis of many neural diseases. FSE-based diffusion imaging techniques are insensitive to susceptibility artifacts. However, they violate the CPMG condition that leads to degraded signal. To address this issue, DW-PROPELLER [1] was proposed by using an XY2 phase modulation. However, this still requires the refocusing RF pulse...
متن کاملImplementing VERSE for Time of Flight RF pulses at 7Tesla: Methodological Considerations
INTRODUCTION. In Time-of-flight (TOF) angiography, fresh blood inflowing spins provide bright intravascular signal while static tissue signal suppression is obtained in the steady state with TR<<T1. At 1.5 and 3T, stronger background suppression is achieved with magnetization transfer (MT), and venous contribution is attenuated with saturation RF pulses. Ramp shaped RF pulses (TONE) can be used...
