概括
血液血管瘤中高PSMA表达可能会误导PET/CT扫描. 这项研究详细介绍了两个III级病例,其中一个接受了使用225Ac-PSMA-617的向α疗法,突出了潜在的诊断陷和治疗方法.
科学领域:
- 在瘤学瘤学.
- 核医学就是核医学.
- 放射性药物 放射性药物 放射性药物
背景情况:
- 血瘤是一种中细胞瘤,起源于细胞周围细胞.
- 这些瘤可以过度表达前列腺特异性膜抗原 (PSMA).
- 在-68 PSMA-11 (68Ga-PSMA-11) 位子发射断层扫描/计算机断层扫描 (PET/CT) 成像中,PSMA过度表达可能会导致诊断挑战.
研究的目的:
- 报告两例复发的III级血液细胞瘤病例.
- 为了突出这些瘤中高68Ga-PSMA-11吸收的诊断陷.
- 介绍一个用向阿尔法疗法治疗的病例.
主要方法:
- 综述了两例患有复发性输血管细胞瘤的病例.
- 对68Ga-PSMA-11 PET/CT成像检测结果的分析.
- 在一个患者中给予225Ac-PSMA-617向性阿尔法疗法.
主要成果:
- 这两位患者都出现了复发的III级血管细胞瘤.
- 在两种情况下,在PET/CT上观察到68Ga-PSMA-11的高吸收率.
- 一名患者成功接受了225Ac-PSMA-617的向α疗法.
结论:
- 血细胞瘤可以表现出高PSMA表达,模仿其他PSMA的恶性瘤.
- 68Ga-PSMA-11 PET/CT可能导致血液血管细胞瘤的误诊.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
116
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

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...
