概括
这项研究表明,2-deoxy-2-[18F]fluoro-d-glucose正子发射断层扫描/计算机断层扫描 (18F-FDG-PET/CT) 放射学可以准确地预测入侵性导管性乳腺癌 (IDC) 患者的哨戒淋巴结 (SLN) 转移.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 哨兵淋巴结活检 (SLNB) 是检测乳腺癌转移的标准,但具有侵入性.
- 与SLNB相关的并发症需要开发少入侵的诊断方法.
- 评估在侵入性导管癌 (IDC) 中SLN转移的评估的非侵入性技术至关重要.
研究的目的:
- 用F-FDG-PET/CT来评估IDC患者SLN转移的非侵入性放射性分析的诊断性能.
- 通过临床和代谢参数识别SLN转移的预测因素.
- 开发和验证SLN状态的预测模型.
主要方法:
- 在手术前接受F-FDG-PET/CT的132名IDC患者的回顾性分析.
- 从PET和CT扫描中提取放射性特征.
- 使用随机森林 (RF),决策树 (DT) 和k-最近邻居 (KNN) 分类器开发预测模型.
主要成果:
- 多变量分析确定了Ki 67和瘤与肝脏比率 (TLG) 作为独立的预测因素.
- 射频模型在培训队列中达到0.887的最高AUC,在验证队列中达到0.856的最高AUC.
- 放射性特征与临床变量相结合,在预测SLN转移方面具有很高的准确性.
结论:
- 18F-FDG-PET/CT放射学为预测IDC中的SLN状态提供了一个强大的,非侵入性的方法.
- 这种方法可以帮助为乳腺癌患者进行个性化治疗计划.
- 非侵入性放射学可能会减少对侵入性SLNB手术的需要.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
86
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
4.0K
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...
