[Abstract] Objective: To explore the clinical application of half-Fourier acquisition single-shot turbo spin-echo (HASTE) sequence of MRI examination for fetal brain diseases.Materials and Methods: Forty-six cases of pregnant women with ultrasonic diagnosis as diseases or suspected with disease in fetal brain were performed with HASTE sequence scanning by axial view, sagittal view and coronal view. A comparative analysis was performed between the results of HASTE sequence and the results of ultrasound diagnosis.Results: Of the 46 cases, 34 were diagnosed with specific diseases and 12 suspected with abnormal fetal brain by the ultrasonic examination, while 35 cases with 45 specific conditions were found by HASTE sequence and 11 found without abnormal signs. For the liquid lesions, there was a good consistency, 96% (26/27), between ultrasonic examination and HASTE sequence in the group of the lesions ≥3 mm, while only 25% (3/12) consistence was found between ultrasonic examination and HASTE sequence in the group of the lesions <3 mm. For the craniocerebral midline structure diseases and complex intracranial diseases, HASTE sequence was proved to be significantly better than those of ultrasonic examination.Conclusions: HASTE sequence is proved to be a potential tool for validating or correcting the ultrasonic diagnosis in the fetal brain diseases, and is found to be significantly better than ultrasound for the craniocerebral midline structure lesions and parenchymal diseases.
