概括

-68 DOTATATE PET/CT 在异位上腺皮质皮质激素分泌 (EAS) 中显示了比肺瘤更高的肺外瘤检测率. 结合成像技术对于诊断肺部EAS瘤至关重要.

科学领域:

核医学就是核医学.
在瘤学瘤学.
放射性药理学是一种放射性药理学.

背景情况:

宫外 adrenocorticotropic 激素分泌 (EAS) 是一种罕见的内分泌疾病.
神经内分泌瘤 (NETs) 是EAS最常见的原因.
精确的瘤定位对于有效的管理至关重要.

研究的目的:

评估Ga-DOTATATE正子发射断层扫描/计算机断层扫描 (PET/CT) 的检测能力,用于肺与导致EAS的肺外瘤.
根据瘤位置,比较Ga-DOTATATE PET/CT的诊断性能.

主要方法:

追溯审查68个Ga-DOTATATE PET/CT扫描从74名患者怀疑EAS.
在39名患者中,本质病理学证实了EAS瘤.
影像检测结果与病理学结果的比较,根据瘤位置分析检测率和SUVmax.

主要成果:

在39名患者中,Ga-DOTATATE PET/CT 正确识别了26名EAS瘤 (总检测率为66.7%).
肺外NET的检测率明显高于肺外NET的检测率 (92.9%),而肺内NET的检测率则高于肺内NET (52%) (P = 0.013).
瘤吸收 (SUVmax) 在肺外瘤 (9.9 ± 6.3) 显著高于肺瘤 (3.1 ± 2.1) (P = 0.015).

结论:

⁶⁸Ga-DOTATATE PET/CT在检测EAS瘤方面表现出特定部位的性能差异.
与肺 NET 相比,射线追踪器在肺外 NET 中显示出更高的检测率和更高的瘤吸收率.
建议整合解剖成像模式,以准确诊断肺部EAS相关的瘤.

Positron Emission Tomography

Positron Emission Tomography

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...
