Imaging Studies II: Positron Emission Tomography and Scintigraphy

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

为了比较两个人类乳腺癌异种移植模型 (MCF7和MDA-MB-231) 的RT反应.
为了研究低分化与消耗性RT的治疗方案特异性血管效应.

主要方法:

在体内进行多尺度和多光谱断层光声成像 (PAI).
在RT前,RT后和终点进行的PAI,得到了ex vivo免疫组织化学的支持.
在MCF7和MDA-MB-231异种移植中对低分离和废除RT方案的比较.

主要成果:

拥有更密集的血管系统的MCF7异种移植显示出比MDA-MB-231更好的RT反应.
较高的RT前氧化率与改善的结果相关.
PAI检测到治疗方案特定的血管变化,包括血管修剪和改变的氧化.

结论:

PAI可以识别替代生物标志物来预测RT反应.
PAI有效地监测瘤血管对不同RT方案的反应.
PAI显示了评估放射电阻和指导治疗决策的潜力.
