概括

阶段内和阶段外MRI显示中等到良好的可靠性来评估股骨支柱版本的股骨支柱冲击 (FAI),可能减少对CT扫描的需求. 这种MRI协议为评估FAI骨形态提供了可靠的替代方案.

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.
医疗成像医学成像

背景情况:

计算机断层扫描 (CT) 传统上用于成像股骨支骨 (FAI) 骨形态,但涉及电离辐射.
新的MRI协议正在被研究为FAI评估的无辐射替代方案.
与CT相比,在FAI中评估acetabular版本的in- and out-of-phaseMRI序列的可靠性尚未得到充分证实.

研究的目的:

评估使用相位和相位外MRI测量与CT相比,acetabular版本测量的可靠性.
为了比较从常规MRI序列的部形态测量测量与从部特定的CT.

主要方法:

对95名被诊断患有FAI的患者 (100个部) 的回顾性审查,这些患者接受了部特异性CT和相内和相外MRI.
受过奖学金培训的肌肉骨放射科医生从放射学报告中追溯记录了形态测量测量.
使用类内相关系数 (ICC) 和t测试来确定模式间协议的统计分析.

主要成果:

与CT相比,在相位和相位外的MRI显示了与CT相比,对乙体版本的测量具有中等到良好的可靠性 (ICCs 0.62-0.80).
与CT相比,常规的MRI序列显示其他形态测量结果的一致性差到中等 (ICCs 0.41-0.73),而其他形态测量结果与CT相比较.
在相内和相外的MRI协议显示可靠的协议与CT对acetabular版本.

结论:

阶段内和阶段外MRI协议在FAI中对评估acetabular版本提供中等到良好的可靠性,与CT相似.
这些MRI序列可以有效地评估部骨和软组织形态,可能减少对CT的依赖.
外科医生可以考虑选择性地使用CT来评估FAI,未来的研究将探索额外的MRI序列.

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...

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...
