A method for functional mapping of ventricular contraction and phase was developed using gated blood-pool SPECT. Parameters of contraction and phase were calculated using length-based and count-based Fourier analyses. In length-based Fourier analysis (LFA), percentage-shortening and length-based phase were calculated based on the changes of lengths from a ventricular centre to edges. In count-based Fourier analysis (CFA), phase and amplitude were also calculated using serial tomographic phase images. Two-dimensional polar display format was employed to summarize the SPECT data of whole cardiac surface. This program was applied to evaluate coronary artery disease and conduction anomalies. The polar functional map using gated blood-pool SPECT can be an effective method to integrate three-dimensional cardiac information in conjunction with myocardial SPECT studies.
利用门控心血池单光子发射计算机断层扫描（SPECT）开发了一种心室收缩和相位功能映射的方法。使用基于长度和基于计数的傅里叶分析来计算收缩和相位参数。在基于长度的傅里叶分析（LFA）中，基于从心室中心到边缘的长度变化来计算缩短百分比和基于长度的相位。在基于计数的傅里叶分析（CFA）中，还使用连续断层相位图像来计算相位和振幅。采用二维极坐标显示格式来汇总整个心脏表面的SPECT数据。该程序用于评估冠状动脉疾病和传导异常。使用门控心血池SPECT的极坐标功能图可以是一种结合心肌SPECT研究整合三维心脏信息的有效方法。
