Zusammenfassung
Purpose: The purpose of this study was to evaluate signal-to-noise-ratio (SNR) and contrast-to-noise-ratio (CNR) as well as image quality (IQ) of ultrashort-echo-time (UTE) magnetic resonance imaging (MRI) in comparison to newly available zero-echo-time (ZTE) MRI for assessment of the lung parenchyma in small animal high-field MRI. Material & Methods: MR imaging of the mouse lung was conducted on a 4.7 T small animal scanner (Bruker BioSpec) using a transmit-receive RF coil with a three-dimensional UTE sequence (TE/TR 20µs/8ms, acquisition matrix: 128×128, field of view: 4.5×4.5cm, acquisition time: 6min 50s) as…
