概括
磁共振 (MR) 指导的周根神经根注射疗法 (PRT) 是可行的,显示与CT指导相似的针刺时间. 然而,由于规划序列,MR引导的PRT需要更长的总干预时间.
科学领域:
- 医疗成像医学成像
- 干预性放射学 干预性放射学
- 神经学 神经学
背景情况:
- 周周激素注射疗法 (PRT) 是管理脊柱疼痛的常见程序.
- 包括CT和MRI在内的PRT的指导系统旨在提高准确性和安全性.
- 评估像实时MRI这样的新型指导技术对于推进微创治疗至关重要.
研究的目的:
- 评估0.55 TMR导向的近根神经根注射疗法 (PRT) 的准确性和可行性.
- 为了比较MR引导的PRT与CT引导的PRT (常规和激光辅助) 使用腰椎幻影.
- 评估不同指导模式的程序时间和主观结果.
主要方法:
- 五位放射科医生在腰椎幻影上进行了九次PRT手术.
- 程序由实时MRI,常规CT或使用激光导航系统的CT指导.
- 对干预措施进行了准确性和时间评估,经验丰富的神经放射学家对干预措施进行了主观评估.
主要成果:
- 所有程序在技术上都是成功的,在指导方法 (中位数5) 中,主观准确度得分相似.
- 在MR指导的 (178 ± 117秒) 和CT指导的PRT (186 ± 73秒到218 ± 91秒) 之间,纯穿孔时间没有显著差异.
- 总干预时间在MR引导的PRT (700±182秒) 与CT引导的方法 (358±150秒至366±85秒) 相比,显著更长.
结论:
- 实时0.55 T MRI指导对于腰部神经PRT是可行的.
- 用MR指导的PRT显示了与CT指导相比较的穿孔精度.
- 在MR指导的PRT中,增加的总干预时间归因于较长的规划序列,这表明有可能进行优化.

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...
Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Imaging Studies for Cardiovascular System IV: CMRI
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
