SPECT-CT——核医学影像技术的新阶段

Functional anatomical image fusion with a hybrid SPECT-CT an new stage of the developing nuclear medicine techniques

精确的解剖定位一直是具有功能特异性的SPECT所追求的目标。SPECT与CT融合系统为临床诊疗提供了丰富的信息，其良好的定位功能进一步巩固了SPECT的临床地位。在心脏病学中，SPECT-CT可提供准确的衰减图或心功能影像，有利于早期和更准确的诊断。在肿瘤病学中，可对神经内分泌瘤等原发或转移病灶的位置、性质等作出准确判断，有利于临床制定切实可行的诊疗措施。在常规核医学的应用中，能够较为准确地寻找感染灶以及为肺栓塞形态学罐注缺损关系的评估提供精确的方法。SPECT-CT带来了清晰的解剖图像并加快了工作流程。

To obtain a function of precise anatomical localization, it is a goal that SPECT with functional sensitivity aspire to all through. Although the SPECT hybrid system with non-diagnostic CT could provided more information for clinical practice. It＇s better function of anatomical localization has confirmed further the role of SPECT in clinical practice. It has a good future in application that is could provide accurate image of attenuaton and function of heart in cardiovascular disease, so that in favor of diagnosis early and accurately. The hybrid SPECT-CT help improved planning of diagnosis and therapy for patients with cancer such as ectopic parathyroid tumours, neuroendocrine tumours, and prostate cancer so on that it could evaluate accurately position and characters to those primary or focus of metastases tumours. In general nuclear medicine. It could help clinicians accurately locate the source of infection and improve the sensitivity of diagnosis and Improved therapy planning optimized for each individual patient, it also provide an accurate assessment of the morphological-perfusion defect relationship. The SPECT-CT brought high accurateness for functional and anatomical image and so improve workflow.
