Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

4.9K
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

150
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...

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...

中心环状断裂 (MAD) 经常通过心磁共振 (CMR) 检测到,但很少通过横心回声 (TTE) 检测到. 提高诊断值可以提高MAD的这些成像方法之间的一致性.

科学领域:

  • 心脏病学 心脏病学
  • 医疗成像医学成像
  • 心声回声扫描 (Echocardiography) 是一种心声回声扫描.

背景情况:

  • 中心环状断裂 (MAD) 是一个鲜为人知的心声回声学发现.
  • MAD的患病率可能因所使用的成像方式而异.
  • 马德的临床意义仍然不确定.

研究的目的:

  • 为了评估MAD的患病率,使用跨胸腔心声学 (TTE) 和心磁共振 (CMR) 来评估MAD的患病率.
  • 评估TTE和CMR之间用于MAD检测的跨模式协议.
  • 调查诊断标准对MAD患病率和同意的影响.

主要方法:

  • 观察性回顾性研究,包括124名在6个月内接受TTE和CMR治疗的患者.
  • MAD定义为左心室壁与左心室壁之间的缩距离≥1mm.
  • 测量了最大的MAD纵向范围;使用科恩的卡帕和ICC分析了跨模式协议.

主要成果:

  • 通过CMR (n=60) 检测到48%的MAD患者,而通过TTE (n=10) 检测到8%的患者.
  • 当诊断切线增加到5mm (kappa = 0.66) 时,低间模式协议 (科恩的kappa = 0.17) 显著改善.
  • 中位数MAD长度:CMR2.0毫米,TTE4.0毫米;中等协议 (ICC=0.66).

结论:

  • 在CMR中,有限程度的MAD是常见的,大多数病例被TTE遗漏.
  • 将MAD的诊断值从1毫米提高到5毫米,提高了TTE-CMR协议.
  • 在MAD评估方法中的差异导致了不同的流行率和临床意义报告.
