MOLLI
Pronunciation: molly
Also written as: MOLLI — Modified Look-Locker Inversion Recovery
Modified Look-Locker inversion recovery sequence used for T1 mapping in cardiac MRI with motion correction capabilities.
Full Definition
Modified Look-Locker Inversion Recovery (MOLLI) is a cardiac MRI pulse sequence specifically designed for T1 mapping of the myocardium. The sequence uses multiple inversion recovery measurements with different inversion times, combined with motion correction algorithms to account for cardiac and respiratory motion. MOLLI provides rapid T1 mapping within a breath-hold, making it clinically practical for routine use. The technique samples multiple points along the T1 recovery curve and uses curve fitting to calculate accurate T1 relaxation times for each pixel in the image.
Usage
Usage note: Pronounce as 'molly' not as individual letters.
