概括
[F] - - 甲基基氨 ([F]MFBG) PET成像显示的诊断性能与针对神经母细胞瘤的体静止素受体 (SSTR) 向的PET相美. 不建议进行常规的双标志物成像,保留它用于特定的治疗考虑,如放射性核素治疗.
科学领域:
- 核医学就是核医学.
- 在瘤学瘤学.
- 放射化学 放射化学是指辐射化学.
背景情况:
- 神经母细胞瘤成像依赖于各种PET标记物,其中[F]-meta-fluorobenzylguanidine ([F]MFBG) 和 somatostatin受体 (SSTR) 向的药物是突出的.
- [18F]MFBG PET与SSTR向PET在神经母细胞瘤中的比较诊断效用和临床影响仍需明确定义.
研究的目的:
- 在神经母细胞瘤患者中,前性地比较[18F]MFBG PET与SSTR向PET ([68Ga]Ga-DOTATATE或[18F]AlF-NOTA-octreotide) 的诊断性能.
- 评估这些成像方法对患者管理的潜在临床影响.
主要方法:
- 这是一项前性,两中心研究,涉及16名有神经母细胞瘤病史的患者.
- 进行了与[18F]MFBG PET和SSTR向PET的对照成像.
- 分析包括病变检测率,库里得分和每患者和每病变的标记剂吸收指标.
主要成果:
- 无论是[18F]MFBG和SSTR PET,在所有12名患有活跃疾病的患者中都发现了病变;四名患者有一致的阴性扫描显示缓解.
- [18F]MFBG检测出更多的病变 (292) 比SSTR PET (243),具有显著更高的整体库里得分 (130比90,p=0.028).
- 通过SSTR PET没有独特地确定任何具有临床意义的发现,当[18F]MFBG PET可用时改变了管理.
结论:
- [18F]MFBG PET/CT在神经母细胞瘤中表现出卓越的诊断性能,与针对SSTR的PET相美.
- 不建议进行常规的双标志物成像;建议根据治疗考虑选择性使用,例如计划的放射性核素治疗.

Positron Emission Tomography
5.7K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
