概括
低剂量乳房向正子发射断层扫描 (PET) 图像显示,它有望减少乳房MRI的不确定性. 这种分子成像技术可以独立于荷尔蒙变化检测恶性瘤,在减少辐射暴露的情况下提供更高的特异性.
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:
- 与对比度增强的乳腺磁共振成像 (MRI) 是高风险女性的敏感查工具,但具有包括荷尔蒙敏感性和高错误阳性率在内的局限性.
- 用乳腺向的正子发射断层扫描 (PET) 进行的分子成像在检测恶性瘤方面具有潜在的优势,无论乳腺密度和荷尔蒙波动如何,其特异性高于MRI.
- 传统的PET成像涉及高剂量的辐射,限制其在重复查或未诊断患者的使用.

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