HASTE (half-Fourier acquisition single-shot turbo spin echo) is a sequence that enables T2 weighted magnetic resonance (MR) images to be obtained in a few seconds. The purpose of this study was to evaluate the usefulness of this sequence in the diagnosis of fetal cerebral abnormalities. Five fetuses suspected of having cerebral abnormalities on ultrasound examination were studied by MR imaging using the HASTE sequence in utero. We compared the images with post-natal MR images or computed tomography (CT) scans. In four fetuses, the abnormality was diagnosed correctly, and the diagnosis was almost correct in the remaining fetus. This sequence is useful because it provides images of diagnostic quality in a very short scanning time.
HASTE（半傅里叶采集单次激发快速自旋回波）序列能够在数秒内获取T2加权磁共振（MR）图像。本研究的目的是评估该序列在胎儿脑异常诊断中的实用性。对5例超声检查怀疑有脑异常的胎儿在子宫内使用HASTE序列进行磁共振成像研究。我们将这些图像与产后磁共振图像或计算机断层扫描（CT）进行了比较。在4例胎儿中，异常得到了正确诊断，在其余1例胎儿中诊断几乎正确。该序列很有用，因为它能在非常短的扫描时间内提供具有诊断质量的图像。
