概括
创伤后多个下肢区域的常规X射线显示诊断产量低. 最初的成像更有效,这表明临床评估应该指导成像,以减少不必要的X射线.
科学领域:
- 放射学 放射学是一门学科.
- 紧急医疗 紧急医疗
- 整形外科 整形外科 整形外科
背景情况:
- 医学成像,特别是X射线,对于在急诊室诊断下肢创伤至关重要.
- 由于担心同时受伤或重叠症状,经常要求同时对多个下肢区域进行X射线.
研究的目的:
- 为了评估创伤后成像多个下肢区域的诊断产量.
- 为了确定初始X射线成像与二次X射线成像在检测异常方面的有效性.
主要方法:
- 对来自两个医院的成年患者的下肢成像请求进行了回顾性审计.
- 收集的数据包括要求的区域,临床史,以及24小时内初始和二次相邻X射线的放射学发现.
- 使用奇平方的统计分析被采用.
主要成果:
- 在1473次检查中,初始X射线在诊断新发现或可疑发现方面比二次X射线有效得多 (p < 0.001).
- 在12.4%的X射线中检测到异常,在初始成像中发现了87.4%,在二次成像中只有12.6%.
- 在相邻的下肢区域同时发生的损伤很少,仅发生在0.9%的患者中.
结论:
- 在创伤后成像多个相邻的下肢区域具有较低的诊断产量.
- 进行彻底的临床评估至关重要,以尽量减少下肢创伤病例中低值成像.
- 二次X射线的诊断价值是最小的,特别是在无症状患者.

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...

Imaging Studies for Cardiovascular System III: X-Ray
298
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...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
