= Inversion recovery
{wiki=Inversion_recovery}
Inversion recovery is a technique used in magnetic resonance imaging (MRI) to enhance the contrast of images by manipulating the relaxation properties of tissues. The fundamental principle behind inversion recovery involves applying an inversion pulse to the spins of hydrogen nuclei (protons) in the body. Here’s how it works: 1. **Inversion Pulse**: The sequence starts with a 180-degree radiofrequency (RF) pulse that inverts the magnetization of the tissue.
