概括
与长期放射治疗 (LCRT) 相比,直肠癌的短期放射治疗 (SCRT) 显著减少了患者的旅行和相关的温室气体 (GHG) 排放. 这种转变为癌症护理提供了更绿色的方法.
科学领域:
- 环境健康 环境健康
- 在瘤学瘤学.
- 辐射疗法 辐射疗法
背景情况:
- 医疗保健行业对全球温室气体 (GHG) 排放作出了重大贡献,运输占美国医疗保健环境足迹的很大一部分.
- 辐射疗法 (RT) 是癌症治疗的基石,涉及大量的患者访问,并为环境管理提供了机会.
- 对直肠癌的短期RT (SCRT) 已经显示出与传统的长期RT (LCRT) 相似的临床结果.
研究的目的:
- 调查与SCRT与直肠癌的LCRT相关的环境结果,特别是患者运输的温室气体排放.
- 评估SCRT在减少辐射瘤实践对环境足迹方面的潜力.
主要方法:

Biological Effects of Radiation
15.6K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
118
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...

Radiation: Applications
1.2K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
115
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
