Single-shot T2-FLAIR mapping via inversion recovery multiple overlapping-echo acquisition and deep neural network reconstruction

T2-weighted imaging via conventional FLAIR sequence can suppress the signal of cerebrospinal fluid (CSF), making it easier for identifying long T2 lesions in the vicinity of the CSF. But it was usually used for qualitative analysis because of its inevitable time-consuming acquisition. In this study, we applied inversion recovery overlapping-echo acquisition together with deep learning-based reconstruction to achieve ultra-fast T2-FLAIR mapping. In vivo results from a healthy volunteer and two glioma patients demonstrate the good accuracy and robustness of our proposed method.
