A new radionuclide tomographic scanner produces 12 tomographic brain images instead of a single conventional brain scan. This scanner has important advantages over conventional radionuclide scanning. The size, shape, and extent of a lesion and its relationship to surrounding structures are better defined. Tomography often permits a firm diagnostic impression in studies that would be equivocal with the use of routine scanning. Tomography may also be used in conjunction with radionuclide cisternography to provide a clear visualization of the CSF pathways and ventricles and to distinguish overlying structures.
一种新型放射性核素断层扫描仪可生成12张脑部断层图像，而非单一的传统脑部扫描图像。与传统放射性核素扫描相比，这种扫描仪具有重要优势。病变的大小、形状和范围及其与周围结构的关系能得到更清晰的界定。在一些使用常规扫描会难以明确诊断的研究中，断层扫描常常能得出确切的诊断印象。断层扫描还可与放射性核素脑池造影联合使用，以清晰显示脑脊液通路和脑室，并区分覆盖其上的结构。
