Abstract

Brain T~1~ mapping has important clinical applications in detecting brain disorders. Conventional T~1~ mapping techniques are usually based on inversion recovery spin echo (IRSE) imaging or its more time‐efficient counterpart inversion recovery fast spin echo (IRFSE) imaging because they can deliver good image quality. Multiple inversion times are required to accurately estimate T~1~ over a wide range of values. Without acquisition optimization, both the IRSE and the IRFSE T~1~ mapping techniques require long scan times to image the whole brain. To reduce the scan time and maintain the quality of the T~1~ maps, we propose a new full‐brain T~1~ mapping pulse sequence based on a multislice inversion recovery fast spin echo imaging using a time‐efficient slice ordering technique.
