- 医学成像
- 辐射学
背景情况:
- 对于个性化治疗策略来说,准确的术前分类对成人类型的扩散性质瘤至关重要.
- 瘤透可能超出可见的周围,但其在放射学中的预测价值仍未得到充分研究.
研究的目的:
- 调查周围瘤区域的放射性特征的预测价值,以进行成人类型扩散性质瘤的手术前分类.
- 开发和评估包含内和周体积的放射学模型,以改善质瘤分类.
主要方法:
- 来自UCSF-PDGM数据集的180例成年型扩散性质瘤的回顾性分析.
- 分析了各种扩张距离 (1-15毫米) 的内体 (VOI_I) 和周围体 (VOI_P) 体积.
- 使用统计测试和机器学习 (mRMR,LASSO) 选择了放射性特征;使用AUC,精度,灵敏度,特异性和F1得分来评估模型.
主要成果:
- 与单独使用内体积 (VOI_I) 相比,使用内体和周区域5mm (VOI_1-5mm) 的综合放射学模型显示出更高的预测性能.
- VOI_ 1模型的性能最高,AUC为0. 903 (训练) 和0. 904 (验证).
- 随着周扩张距离 (10-15毫米) 的增加,模型的性能下降,这表明微妙的透区域的重要性.
结论:
- 在瘤5毫米以内的周围瘤区域包含了手术前质瘤分类的关键信息.

Radiation: Applications
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.

Gauss's Law: Problem-Solving
Gauss's law helps determine electric fields even though the law is not directly about electric fields but electric flux. In situations with certain symmetries (spherical, cylindrical, or planar) in the charge distribution, the electric field can be deduced based on the knowledge of the electric flux. In these systems, we can find a Gaussian surface S over which the electric field has a constant magnitude. Furthermore, suppose the electric field is parallel (or antiparallel) to the area vector...
Positron Emission Tomography
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 being...

Absorption of Radiation
The rate of heat transfer by emitted radiation is described by the Stefan-Boltzmann law of radiation:
Radiation Pressure: Problem Solving
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force per...

Gravitation Between Spherically Symmetric Masses
The gravitational potential energy between two spherically symmetric bodies can be calculated from the masses and the distance between the bodies, assuming that the center of mass is concentrated at the respective centers of the bodies.
