近年来，随着SPECT/CT融合显像的发展，99Tcm-MIBI作为一种应用广泛的亲肿瘤显像剂在颅内占位病变的应用价值变得越来越高。本文介绍了99Tcm-MIBI的显像机制，阐述了99Tcm-MIBI SPECT/CT同机融合显像对颅内占位病变的临床应用价值，并与多模态影像技术进行了分析与比较。

Abstract：In recent years, with the development of SPECT/CT fusion imaging, the value of 99Tcm-MIBI used tumor imaging agent in diagnosis of intracranial lesions was highly recognized. This paper introduced the imaging mechanism of 99Tcm-MIBI, explored the clinical application value of 99Tcm-MIBI SPECT/CT fusion imaging in the intracranial space-occupying lesion, and also compared with Multi modality imaging technology to analysis their differences.
