T2 Relaxation during Radiofrequency (RF) pulses

, 2023
Radiofrequency (RF) pulses are a critical part of every MRI pulse sequence, and must be specifically designed for ultrashort echo time (UTE) and zero echo time (ZTE) acquisitions.

Using adiabatic inversion pulses for long‐T₂ suppression in ultrashort echo time (UTE) imaging [PDF]

Magnetic Resonance in Medicine, 2007
AbstractUltrashort echo time (UTE) imaging is a technique that can visualize tissues with sub‐millisecond T2 values that have little or no signal in conventional MRI techniques. The short‐T2 tissues, which include tendons, menisci, calcifications, and cortical bone, are often obscured by long‐T2 tissues.

Fast 3D UTE in vivo T1 and T2*$$ {\mathrm{T}}_2^{\ast } $$ mapping of fast relaxing knee tissues at 3 T

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 693-705, February 2026.
Abstract Purpose UTE MR imaging captures quantitative signals in fast‐relaxing tissues, enabling anatomical visualization and quantitative assessment of T1 and T2*$$ {\mathrm{T}}_2^{\ast } $$ relaxation times. However, the clinical application of quantitative UTE MRI is limited by long acquisition times.
