Zero echo time (ZTE) imaging is an established approach for three-dimensional imaging of tissues and materials with ultrashort T2* relaxation times. An intrinsic disadvantage of this approach are missing data points within the center region of k-space due to hardware limitations. These missing points are often retrospectively interpolated or subsequently acquired using single-point imaging approaches or additional ZTE acquisitions with decreased resolutions. This abstract presents an approach that relies on the interleaved combination of ZTE read-outs with different resolutions combined with a Compressed Sensing reconstruction, to acquire more information around the k-space center, for high-quality ZTE without prolonged acquisition times.
