Abstract
Despite the recent progress of MR imaging, visualization of the cranial nerves within the brain stem has not been accomplished. Periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) multishot diffusion-weighted imaging, an effective method for compensating for motion and distortion, offers high-quality diffusion-weighted images. We succeeded in depicting the cranial nerves within the brain stem in some subjects by using this method with motion-probing gradient applied in the superior-inferior direction.
摘要
尽管磁共振成像（MR成像）最近取得了进展，但脑干内颅神经的可视化尚未实现。周期性旋转重叠平行线增强重建（PROPELLER）多次激发扩散加权成像作为一种有效补偿运动和畸变的方法，可提供高质量的扩散加权图像。我们通过在上下方向应用运动探测梯度的这种方法，成功在一些受试者中描绘出了脑干内的颅神经。
