摘要: 抑郁症的影像学检查有结构性脑成像和功能性脑成像,CT和MRI检查脑结构的异常既不显著又不具有特异性,而PET和SPECT提供了在活体内对抑郁症进行局部脑血流灌注和中枢神经递质与受体结构和功能的研究,为进一步探讨抑郁症的病因、发病机制以及临床治疗提供客观依据.Abstract: The imaging methods of depressive disorders include structural imaging and functional imaging, the abnormal of cerebral structure in CT and MRI is neither significant nor specific, while the use of PET and SPECT provides depression study in-vivo about regional cerebral blood flow and central neurotransmitter and receptor's structure and function, which further have advanced research on aetiology, pathogenesis and therapy of depressive disorders.
