Multislice multishot Inversion Recovery sequences as implemented in standard systems are often not optimized for efficiency. This becomes a critical factor when imaging neonates, where T1 is longer and the Inversion Time needs to increase to maintain the desired contrast. In this study, we have optimized a standard Inversion Recovery sequence and used it for an optimised neonatal protocol. The proposed sequence provides a total scan time reduction of 44% with identical imaged contrast and resolution.
