研究目的:

评估4.5×CS 加速 3.0T 无对比剂 CMRA检测冠状动脉≥50% 狭窄的诊断效能(敏感度、特异度、准确度、阳性 / 阴性预测值); • 验证 4.5×CS 技术在缩短扫描时间、降低运动伪影、维持图像质量(信噪比 SNR、对比噪声比 CNR)方面的临床价值; • 明确该技术在对比剂过敏、肾功能不全、需反复随访等特殊人群中的应用优势,推动其临床转化与规范化应用。  

Objectives of Study:

The diagnostic efficacy ( sensitivity, specificity, accuracy, positive / negative predictive value ) of 4.5 × CS accelerated 3.0T contrast-free CMRA in detecting coronary artery stenosis >= 50 % was evaluated. To verify the clinical value of 4.5 × CS technology in shortening scanning time, reducing motion artifacts, and maintaining image quality ( signal-to-noise ratio SNR, contrast-to-noise ratio CNR ) ; To clarify the application advantages of this technique in special populations such as contrast agent allergy, renal insufficiency, and repeated follow-up, and to promote its clinical transformation and standardized application.
