概括
偶然的前列腺18F-FDG-PET/CT吸收并不总是癌症的迹象. 多参数MRI (mpMRI) 和前列腺成像报告和数据系统 (PI-RADS) 的得分比单独的PET/CT发现更可靠地预测恶性瘤.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 18F-FDG-PET/CT对许多癌症有价值,但不建议用于局部性前列腺癌.
- 在前列腺中18F-FDG吸收的偶然发现需要进一步的表征.
- 多参数MRI (mpMRI) 可提供详细的前列腺成像.
研究的目的:
- 调查mpMRI在描述前列腺中偶发的18F-FDG吸收方面的实用性.
- 为了比较mpMRI发现的预测价值与前列腺癌恶性病的18F-FDG-PET/CT指标.
主要方法:
- 评估了92名患有偶发18F-FDG-PET/CT前列腺吸收的患者.
- 使用了mpMRI序列 (T2W,DCE,ADC) 和PI-RADS v2.1评分.
- 与30名患者的mpMRI和活检结果相关的PET/CT发现 (SUVmax,吸收模式).
主要成果:
- 偶然摄取18F-FDG的70.6%与mpMRI发现没有相关性.
- 在PI-RADS 3-5病变 (29.3%) 中观察到相关性.
- 活检显示56.7%的恶性;PSA密度,PSA水平和PI-RADS得分是显著的预测因素,与SUVmax或吸收模式不同.
结论:
- 偶然的18F-FDG-PET/CT前列腺吸收需要仔细解释.
- 高PSA密度,PSA水平和PI-RADS得分比PET/CT发现更能预测恶性瘤.
- mpMRI在评估偶发性前列腺18F-FDG吸收方面发挥着至关重要的作用.

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...
