概括
背景抑制单次射击心电图触发非对比增强磁共振血管造影 (BASS-TRANCE) 的诊断准确性与外周动脉疾病 (PAD) 的计算机断层扫描血管造影 (CTA) 的诊断准确性相当. 这种非对比增强磁共振血管造影 (NCE-MRA) 技术是PAD评估的一个有希望的,安全的替代方案.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 心血管疾病 心血管疾病
背景情况:
- 外周动脉疾病 (PAD) 的评估通常依赖于对比度增强成像.
- 非对比增强磁共振血管学 (NCE-MRA) 提供了一个替代方案,BASS-TRANCE (背景抑制单次射击心电图触发非对比增强磁共振血管学) 是最近的一项进展.
- 与已建立的方法相比,BASS-TRANCE的诊断性能如计算机断层扫描血管造影 (CTA) 和PAD的数字减去血管造影 (DSA) 需要澄清.
研究的目的:
- 在患有PAD的患者中,与CTA相比,评估BASS-TRANCE的图像质量和临床诊断精度.
- 确定BASS-TRANCE是否是PAD诊断中CTA的可行替代品,使用DSA作为黄金标准.
主要方法:
- 一项涉及30名PAD患者的研究,这些患者接受了BASS-TRANCE,CTA和DSA.
- 图像质量由两名医生使用3分级评分,并使用5级方法评估狭窄.
- 检测下肢动脉狭窄的灵敏度和特异性>50%使用DSA作为参考标准进行计算.
主要成果:
- 在BASS-TRANCE中,不确定的细分段比CTA (7.4%) 少 (2.1%).
- 在BASS-TRANCE (2.42) 和CTA (2.39) 之间,图像质量得分没有显著差异.
- 对于狭窄的检测,BASS-TRANCE表现出高灵敏度 (92.8%) 和特异性 (96.1%),与CTA (94.9%和96.8%) 相比.
结论:
- 在很短的获取时间内,BASS-TRANCE提供了下肢血管的优秀可视化.
- 它的诊断性能与PAD评估中的CTA相美.
- 贝斯-特朗斯是一种安全有效的成像方法,有可能替代PAD患者的CTA.

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...

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...
