目的:观察~(18)F-FDG肿瘤显像患者中心肌显影的现象及心肌摄取与血糖水平的关系。方法:行~(18)F-FDG肿瘤显像的患者110例,年龄30～87岁,平均64.12±11.53岁。所有患者均空腹显像,胸部采集数据经默认条件处理后观察心脏显影程度。按照心肌显影程度分为4级:1级心肌完全不显影,2级心影高于纵隔影仅少部分清晰,3级心影高于纵隔影少于1/2心室,4级心肌完整显影。结果:72例男性中,心肌完全不显影26例,部分显影17例,完全显影29例,分别占36%,24%,40%,女性38例中,心肌完全不显影23例,部分显影8例,完全显影7例,分别占61%,21%,18%。各组心肌显影程度与空腹血糖(P值均>0.05)无明显关系。结论:肿瘤患者葡萄糖代谢显像心肌显影的程度各不相同,提示肿瘤惠者心肌葡萄糖代谢的复杂性。
OBJECTIVE: To observe the phenomenon of myocardial remodeling and the relationship between myocardial uptake and blood glucose level in ~ (18) F-FDG tumor imaging. Methods: Totally 110 patients with ~ (18) F-FDG tumor imaging were aged 30-87 years with an average of 64.12 ± 11.53 years. All patients were fasting imaging, chest acquisition data by default after treatment to observe the extent of cardiac development. According to the extent of myocardial development is divided into four levels: a grade myocardial no development, grade 2 heart shadow higher than mediastinal only a small part of the clear, grade 3 heart shadow higher than mediastinal less than 1/2 ventricular, 4 grade myocardial complete development. Results: In 72 males, there were 26 cases with no myocardial development, 17 cases with partial development, 29 cases with complete development, accounting for 36%, 24% and 40% respectively. In 38 cases of women, 23 cases were not developed completely, Cases, complete development in 7 cases, respectively, 61%, 21%, 18%. There was no significant correlation between myocardial development and fasting blood glucose (P> 0.05) in all groups. CONCLUSIONS: The extent of myocardial imaging of glucose metabolism imaging in cancer patients varies, suggesting the complexity of myocardial glucose metabolism in cancer patients.
