客观化 对~(89)锶韧致辐射SPECT显像进行了评价，以探测更详细的全身~(89)锶分布。 方法 用双探针式SPECT系统分别采集了~(89)锶韧致辐射全身平面和合并SPECT图像。在连续谱上设置能量窗A(100keV+/-50%)用于平面成像，能量窗A加相邻能量窗B(300keV+/-50%)用于SPECT成像。并与99mTC-H-MDP全身平扫及SPECT图像进行比较。为了验证韧致辐射全身平面图和合并SPECT图所获得的累积，我们根据临床研究成像的计数制作了原始体模。 结果 在~(89)锶-氚-甲基二磷酸核素核素显像中，~(99m)Tc-H-MDP~(99)T-H-MDP在~(99m)Tc-H-MDP的SPECT显像中可见灶性浓聚。~(89)锶-韧致辐射SPECT全身平面图较~(89)Sr~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(-1)~(？)在体模研究中，在平面和SPECT图像上，随着采集时间和旋转次数的增加，每个浓度的计数都呈线性增加。 结论 ~(89)锶-溴致辐射核素SPECT显像有助于更详细地了解~(89)Sr在全身的分布情况。
OBJECTIVE 89Sr bremsstrahlung SPECT imaging has been evaluated for detecting the more detailed whole body 89Sr distribution. METHODS 89Sr bremsstrahlung whole body planar and merged SPECT images were acquired by using two detectors type SPECT system. Energy window A (100 keV +/- 50%) for planar imaging, and energy window A plus adjacent energy window B (300 keV +/- 50%) for SPECT imaging were set on the continuous spectrum. Those images were compared with 99mTc-H-MDP whole body planar and merged SPECT images. To verify the accumulation obtained by bremsstrahlung whole body planar and merged SPECT image, we made original phantom based on the counts of clinical study imaging. RESULTS On 89Sr bremsstrahlung merged SPECT image, focal accumulations were recognized in the parts of 99mTc-H-MDP merged SPECT accumulation. Focal accumulations were much clearer on 89Sr bremsstrahlung merged SPECT imaging than those of whole body planar image of 89Sr bremsstrahlung. In phantom study, counts of each concentration linearly increase as acquisition time and number of rotation increase on planar and SPECT images. CONCLUSIONS 89Sr bremsstrahlung merged SPECT imaging would be useful for detecting the more detailed whole body 89Sr distribution.
