概括
包括后续的X射线并没有改善AI骨折分类,但增强了对儿科手腕骨折的物体检测. 这表明后续数据可以提高AI定位精度在骨折检测.
科学领域:
- 放射学 放射学是一门学科.
- 人工智能的人工智能
- 医疗成像医学成像
背景情况:
- 人工智能 (AI) 显示出在初始X射线上检测骨折的潜力.
- 后续检查对人工智能检测骨折性能的影响尚不清楚.
- 这项研究调查了将随访X射线纳入儿童手腕骨折检测AI模型的效果.
研究的目的:
- 评估包括随访X射线对神经网络在检测儿科手腕骨折中的性能的影响.
- 在使用后续数据时,比较图像分类与对象检测模型的有效性.
- 为了确定后续成像是否提高AI识别和定位骨折的能力.
主要方法:
- 使用了GRAZPEDWRI-DX数据集 (20,327次儿科手腕X射线).
- 在数据集上训练了EfficientNet (分类) 和YOLOv8 (物体检测) 模型,仅使用初始X射线和后续X射线 (包括件).
- 通过使用精度,回忆,F1得分和平均精度 (AP) 度量来评估性能.
主要成果:
- 效率网分类表现显示,随着随访X射线,没有显著的改善.
- 在包括后续X射线时,YOLOv8对象检测显示了AP50 (p=0.003) 和F1得分 (p=0.009) 的显著改善.
- 在物体检测中获得的最实质性的收益是在加入造和非造后续图像时观察到的.
结论:
- 随访X射线没有提高儿童手腕骨折的AI分类准确性.
- 纳入后续数据改善了物体检测模型 (YOLOv8) 的骨折定位能力.
- 这些发现表明,虽然后续数据可能不会提高检测率,但它可以改进儿童手腕成像中骨折定位的AI应用.

4.9K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

01:20Imaging Studies for Cardiovascular System III: X-Ray
447
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...
