✦ Synopsis

Abstract

It is now possible to detect signals from tissues and tissue components with short T~2~s, such as cortical bone, using ultrashort TE (UTE) pulse sequences. The background to the use of these sequences is reviewed with particular emphasis on MR system issues. Tissue properties are discussed, and tissues are divided into those with a majority and those with a minority of short T~2~ components. UTE pulse sequences and their variants are described and clinical applications are illustrated. System design requirements for sequences of this type, including gradient performance, RF switching, and data‐processing issues, are outlined. J. Magn. Reson. Imaging 2007. © 2007 Wiley‐Liss, Inc.

## Abstract Short __T__~2~ species such as the Achilles tendon and cortical bone cannot be imaged with conventional MR sequences. They have a much broader absorption lineshape than long __T__~2~ species, therefore they are more sensitive to an appropriately placed off‐resonance irradiation. In this
