Sweep imaging with Fourier transform (SWIFT) is a novel 3D radial imaging technique that allows smooth and gradual gradient orientation changes during acquisition. Therefore, a SWIFT acquisition is nearly silent. A basic SWIFT sequence is proton density weighted due to low flip angles and very short echo times. It would be desirable to have a silent imaging technique that can create images with varying contrast. This work describes the use of SWIFT as a readout sequence with T1 and T2 preparation schemes, resulting in T1- and T2- weighted images acquired with minimal acoustic noise.
