Abstract T1WI is a routine sequence for fetal brain MR examination. It is mainly used to evaluate the development of fetal brain, and display hemorrhagic lesions, calcification, protein and fat. In recent years, with the development of fast-sequence MRI, acquisition method and post-processing technique, fetal T1WI has been greatly improved in the following aspects, shortening acquisition time, reducing motion artifacts and interference, and increasing image resolution and signal to noise ratio(SNR). It is valuable and applicable of 3D, T1-weighted gradient-echo imaging(T1WI) fetal brain MR. This article reviews the diagnostic value of T1WI in fetal brain imaging, the characteristics of fetal central nervous system, the development of T1WI, and the clinical application of T1WI in fetal brain imaging.
