Ultra-short TE (UTE) and Zero TE (ZTE) MR pulse sequences provide unique capabilities for imaging short-lived tissues (i.e. T2 < 1ms) which are otherwise invisible using conventional MR imaging with echo times (TE) in the milliseconds range. The presentation will first review 2D and 3D UTE imaging using center-out (typically radial) k-space sampling. Subsequently, ZTE imaging will be described highlighting its unique features regarding RF excitation and silent imaging. At the end of the presentation related methods like SWIFT and Looping Star will be briefly mentioned as well.
