概括
使用动态对比增强MRI (DCE-MRI) 的放射学分析显示,在乳腺癌患者的新辅助化疗 (NAC) 后预测病理完整反应 (pCR) 是有前途的. 这个工具可以帮助临床决策.
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:
- 准确预测病理完整反应 (pCR) 对于定制乳腺癌新辅助化疗 (NAC) 至关重要.
- 动态对比增强型MRI (DCE-MRI) 提供了详细的组织特征.
- 放射学从医学图像中提取定量特征,可能揭示与治疗反应相关的微妙模式.
研究的目的:
- 评估DCE-MRI衍生出的放射学在预测经过NAC的乳腺癌患者的PCR的诊断准确性.
- 评估用于pCR预测的放射学性能指标.
主要方法:
- 在PubMed,Web of Science和Cochrane图书馆进行了系统的文献搜索,直到2023年9月.
- 包含1272例病例的7项研究被纳入了元分析.
- 诊断性能的评估是使用聚合的灵敏度,特异性,正概率比 (PLR),负概率比 (NLR) 和诊断几率比 (DOR) 来评估的.
主要成果:
- 放射学在检测pCR时显示了81%的综合灵敏度和74%的特异性.
- 曲线下的面积 (AUC) 为0.83,表明诊断的准确性很高.

392
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
