中枢神经系统包括脑和脊髓,深藏在骨骼包围的颅腔和椎管内,一般物理学检查不易达到,影像学检查具有重要意义。近30年来,数字X线、CT、磁共振成像(MRI)和超声设备在不断地改进和完善,检查技术和方法也在不断地创新,中枢神经系统的影像诊断已从单一依靠形态变化进行诊断发展成为 Central nervous system, including the brain and spinal cord, deep in the skull surrounded by the bones and spinal canal, the general physical examination is not easy to achieve, imaging examination is of great significance. Over the past 30 years, digital radiography, CT, magnetic resonance imaging (MRI) and ultrasound equipment have been continuously improved and perfected. Inspection techniques and methods are constantly being innovated. The imaging diagnosis of the central nervous system has been diagnosed solely from morphological changes develop into
