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.
