概括
对PET/CT报告进行系统的双重阅读,可以识别轻微和罕见的有影响力的错误,提高瘤学的准确性. 这一过程对于在PET成像中可靠的分期,重新分期和治疗监测至关重要.
科学领域:
- 核医学是一种核医学.
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 越来越多地使用PET/CT在瘤学中用于分期,重新分期和治疗监测,以及治疗术的兴起,导致PET设施的工作量增加.
- 这种需求的增加引发了对PET/CT报告准确性和可靠性的担忧.
研究的目的:
- 为了前性地评估PET/CT报告中的错误频率和性质.
- 评估双重阅读协议在识别和纠正这些错误方面的有效性.
主要方法:
- 一项涉及对PET/CT扫描进行双读的前性研究 ([18F]FDG, [18F]Choline, [18F]Dopa, [18F]PSMA) 于2024年5月至6月期间进行.
- 由第二个读者进行独立审查,与第三个读者协商,就重大变化达成共识.
- 数据收集报告变化 (轻微与有影响),读者信心,诊断假设和潜在影响因素.
主要成果:
- 在17%的PET报告中注意到了变化,而影响性变化很少发生 (例如,治疗监测中的5/20,分期/重新分期的2个主要变化).
- 大多数变化涉及成语/格式 (59%),横向性 (10%) 或不影响TNM分期的目标病变 (29%).
- 报告变化与阅读时间,指示,先前扫描,请求清晰度,读者体验,追踪器类型或患者BMI等因素之间没有发现显著的相关性.
结论:
- 系统的双重阅读有效地识别和纠正PET/CT报告中的轻微和罕见的有影响力的错误.
- 没有确定错误发生的特定预测因素,这强调了对双重阅读的系统方法的必要性.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
89
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...
