概括
由于CT和MRI的使用越来越多,住院放射学工作量从2013-2023财年显著增加,尽管每次调整入院的成像检查较少. 这种向高级成像技术的转变与更长的住院时间有关.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 医疗保健分析 医疗保健分析
背景情况:
- 住院放射学成像利用率和工作量是学术医疗中心的关键指标.
- 了解趋势对于资源配置和患者护理质量至关重要.
研究的目的:
- 评估一个主要的学术医疗中心十年 (财年2013-2023) 的住院放射学成像利用和工作负载趋势.
- 分析成像模式转换对工作量和患者结果的影响.
主要方法:
- 从2013年至2023财年的896,005次住院成像检查 (X光,CT,MRI,US,NM) 的回顾性分析.
- 用病例组合指数调整疾病严重程度的检查;用相对值单位 (RVU) 测量工作负载.
- 线性回归和奇二次测试评估了成像检查的趋势,按病例混合调整入院 (CMAA) 和RVU进行评估.
主要成果:
- 总成像检查增加了,但由于减少了放射,超声和核医学的使用,每次CMAA的检查减少了.
- 放射学工作量 (专业,技术,全球RVU) 显著增加 (p<.001),主要原因是CT和MRI利用率更高.
- 每个CMAA的CT和MRI检查增加了19.2%和21.4%,专业RVUs分别增加了80.6%和90.7%. 平均逗留时间增加了32.1%.
结论:
- 在过去十年中,住院放射学工作量显著增加,这是由于先进的成像 (CT,MRI) 取代了成本更低的模式,尽管疾病严重程度调整利用率下降.
- 对CT和MRI的依赖增加,可能受到COVID-19的影响,与更长的住院时间有关.
- 这些发现凸显了成像实践的转变,影响了医院资源利用率和患者逗留时间.

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

01:20Imaging Studies for Cardiovascular System III: X-Ray
118
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
