UTE imaging and SWIFT are techniques for imaging hard tissues with short T₂ relaxation times on the order of a few tens to hundreds of microseconds. However, implementation of UTE and SWIFT on clinical MRI systems can be challenging due to unique hardware requirements. In some cases, achieving short TE < 1 ms (not ultrashort TE) is all that is required. This can be relatively easily accomplished with the new sequence introduced here, which is called SWIFT-LiTE (SWIFT with Limited TE). SWIFT-LiTE is a 3D radial sampling sequence and can effectively cover the short TE range of > ~0.5 ms.
