Short tau inversion recovery
Short tau inversion recovery (STIR), also known as short TI inversion recovery, is a fat suppression technique with an inversion time TI = ln(2)·T1fat, where the signal of fat is zero. This equates to approximately 140 ms at 1.5 T.
To distinguish two tissue components with this technique, their...

Inversion recovery sequences
Inversion recovery pulse sequences are a type of MRI sequence used to selectively null the signal for certain tissues (e.g. fat or fluid).
Inversion recovery can also generate heavily T1-weighted images and was originally developed for this purpose.
Physics
Basically, an inversion recovery (I...

Zero echo time imaging
Zero echo time (ZTE) imaging is a relatively recent development in MR technology, with the aim to better visualize tissues such as bone with the shortest T2 values.
Physics
In ZTE, the signal is acquired immediately after applying the radiofrequency pulse resulting in near-zero echo times. Af...
