概括
没有对比的磁共振水库图 (MRC) 不是评估内淋巴体水 (EH) 的可靠方法. 使用对比剂的HYDROPS-Mi2成像技术对于EH评估是优越的.
科学领域:
- 放射学 放射学是一门学科.
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 医疗成像医学成像
背景情况:
- 内淋巴体水 (EH) 通常使用HYDROPS-Mi2 MR成像与对比度进行评估.
- 没有对比的MR水库 (MRC) 已被提出作为一种替代方案,但其对EH评估的可行性尚未被证明.
研究的目的:
- 为了比较HYDROPS-Mi2成像用静脉注射对比剂 (IV-GBCA) 与没有IV-GBCA的MR水库成像 (MRC) 的诊断性能,用于评估内淋巴水 (EH).
主要方法:
- 从20名疑似EH患者中分析了40个耳朵,使用MRC (对比前) 和HYDROPS-Mi2 (对比后4小时).
- 在MRC (SH-MRC) 上测量了囊高度和HYDROPS-Mi2 (%ELvolume-HYD) 上测量了内淋巴体积百分比.
- 进行了相关性和ROC分析来比较这些方法.
主要成果:
- 在SH-MRC和%ELvolume-HYD之间没有发现显著的相关性 (斯皮尔曼的rho=0.102).
- 对于%ELvolume-HYD (0.926) 的ROC曲线下的面积明显高于SH-MRC (0.570).
结论:
- 没有IV-GBCA的MRC不是对EH评估的可靠方法.
- 使用IV-GBCA的HYDROPS-Mi2成像显示了EH评估的高诊断性能.

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...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

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,...
