概括

由于膝关节骨关节炎 (OA) 而接受全膝关节整形术 (TKA) 的近五分之一的患者事先接受了MRI,尽管没有说明. 这种做法可能会增加医疗费用和膝盖手术等待时间.

科学领域:

整形外科手术整形外科手术
放射学放射学是一门学科.
医疗保健服务研究医疗服务研究

背景情况:

膝关节整形术 (TKA) 是末期膝关节关节炎 (OA) 的标准治疗方法.
磁共振成像 (MRI) 通常不适用于诊断膝盖OA.
不必要的MRI使用可能会延迟骨科推,增加医疗保健成本.

研究的目的:

确定接受OA初级TKA的患者中,在两年内接受过MRI的比例.
为了确定患者和医生因素与增加的MRI使用TKA之前.

主要方法:

基于人口的队列研究,利用加拿大安大略省的行政数据.
包括40岁以上的患者,他们在2008年4月至2019年3月期间接受了首次初级TKA.
统计分析包括趋势测试和多变量回归,以确定MRI使用的相关性.

主要成果:

194,989名患者有资格接受; 19.6% (38,244) 在TKA前两年内接受了MRI.
主要护理医生订购了这些MRI的大多数 (69.6%).
接受MRI的患者年轻,富裕,并较少出现并发症 (p < 0.001).
在TKA之前的MRI使用从2008年到2018年显著增加 (p < 0.001).

结论:

很大一部分患者 (近五分之一) 在OA的TKA之前接受MRI,尽管指示有限.
这一趋势可能会导致医疗保健支出增加和手术等待时间延长.
对TKA前MRI使用的驱动因素进行进一步调查是有必要的.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
