概括

磁共振成像 (MRI) 和前列腺特异性膜抗原正子发射断层扫描/计算机断层扫描 (PSMA-PET/CT) 在大约一半的前列腺癌 (PCa) 患者中显示出差异. 大多数单一疗法发现表明临床上具有意义的癌症,影响了治疗计划.

科学领域:

在瘤学瘤学.
放射学放射学是一门学科.
核医学就是核医学.

背景情况:

前列腺癌 (PCa) 评估越来越多地使用MRI和PSMA-PET/CT.
多模式成像提供了全面的分期,但可能导致不一致的发现.
了解不一致率对于准确的初级瘤评估至关重要.

研究的目的:

在初级PCa评估中确定MRI和PSMA-PET/CT之间的异常率和类型.
分析仅通过一种成像方式发现的病变的临床意义.

主要方法:

对2021-2023年接受MRI和PSMA-PET/CT的中期和高风险PCa患者的回顾性分析.
使用PI-RADS v2.1和PRIMARY分数进行解释.
不一致性被归类为轻微或主要,并与其病理学相协调.

主要成果:

309名患者中的一半 (49.1%) 显示MRI和PSMA-PET/CT之间的不一致.
在25.7%的不一致病例中发生了重大不一致 (约. 总体来说是八分之一).
仅通过一种模式检测到的病变在80%的病例中具有临床意义.

结论:

在初级PCa分期中,MRI和PSMA-PET/CT之间存在显著的不一致.
这两种模式都提供了互补的信息,单一模式的发现往往代表了重大疾病.
图像检测结果的协调对于PCa最佳治疗计划至关重要.

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...
