| 目的 探讨标准检查条件下非心脏病患者心脏18F-FDG PET显像标准摄取值(SUV)是否受组织CT值的影响。 方法 在我院接受PET/CT检查的患者中随机抽取88例,排除心脏疾病,设立高血压组、贫血组、肿瘤组、正常组4个组,每组22例,观察不同机体状态下心脏组织SUV和CT值,测量左心室侧壁肌、室间隔肌、左心室腔的SUV和CT值,分析各组左心室侧壁肌、室间隔肌、左心室腔CT值和SUV的组间差异,进一步分析各组内不同组织SUV与自身CT值的相关性。 结果 贫血组左心室侧壁肌、室间隔肌、左心室腔CT值低于高血压组、肿瘤组和正常组(P＜0.05),而各组间SUV差异无统计学意义(P>0.05);各组内左心室侧壁肌、室间隔肌、左心室腔SUV与其身CT值无相关性(P>0.05)。 结论 标准检查条件下非心脏病患者心脏组织18F-FDG PET显像SUV与组织CT值无相关性,SUV相对稳定。 |

| Objective To observe whether the heart's 18F-FDG PET standard uptake value (SUV) be influenced by tissue CT value under standard examination condition in subjects without heart disease. Methods Totally 88 cases without heart diseases undergoing 18F-FDG PET of heart were randomly selected and divided into hypertension group, anemia group, cancer group and normal group (each n=22). SUV and CT value of left ventricle lateral wall muscle, interventricular septum muscle and left ventricle cavity were measured and statistically analyzed among 4 groups, and further investigations of the relativity between SUV and self CT value of the above structures were performed. Results In anemia group, CT values of left ventricle lateral wall, interventricular septum muscle and left ventricle cavity were lower than those of the other 3 groups (P＜0.05). There was no significant difference of SUV of above structures among 4 groups (P>0.05), nor relativity between SUV and self CT value of above structures inside every group (P>0.05). Conclusion Under standard examination condition, there is no relativity between tissue SUV and self CT value of heart without diseases, indicating that SUV is relatively stable for certain heart tissue. |
