摘要
目的:比较三种自由呼吸MRCP技术的图像采集时间、总检查时间、图像质量和技术可靠性:生物基质触发(BM-MRCP)、呼吸风箱呼吸门控触发(RG-MRCP)和导航触发(NT-MRCP)。方法:对47例疑似胰腺和胆道疾病接受3.0 t MRCP的患者进行前瞻性个体内比较。2例技术适应性受限患者作为“技术失效”纳入信度分析。在初步分析中,使用了完成所有三种技术的45名患者的数据。图像质量由三名盲法放射科医师(经验:5年、10年、16年)评估。结果:BM-MRCP的中位总检查时间(218[48]秒)明显短于RG-MRCP(228[53]秒)和NT-MRCP(259[53]秒)(p 0.05)。2例患者因呼吸问题出现RG-MRCP或NT-MRCP失败,而BM-MRCP没有失败。结论:BM-MRCP显著减少了检查次数,同时获得了优异的图像质量和技术可靠性。它与临床工作流程的集成提高了效率,减少了技术人员的工作量,并改善了以患者为中心的成像。关键相关性声明:生物基质门控3D-MRCP提高了胆道和胰管系统的成像效率和诊断准确性。通过减少扫描时间和改善工作流程,它支持患者的舒适度和依从性。它的简单性和可靠性也使其成为高通量临床设置的理想选择。重点:生物基质触发(BM)-MRCP缩短了检查时间,帮助患者依从性或局限性。BM-MRCP提供卓越的图像质量,减少运动伪影和更高的清晰度。BM呼吸传感器简化工作流程,提高可靠性,提高患者舒适度。
Advantages of BioMatrix respiratory gating in free-breathing three-dimensional magnetic resonance cholangiopancreatography: a prospective comparative study.
Objectives: To compare the image acquisition time, total examination time, image quality, and technical reliability of three free-breathing MRCP techniques: BioMatrix-triggered (BM-MRCP), respiratory-gating triggered using respiratory bellows (RG-MRCP), and navigator-triggered (NT-MRCP).
Methods: A prospective intra-individual comparison was performed in 47 patients undergoing 3.0-T MRCP for suspected pancreatic and biliary diseases. Two patients with technique adaptability limitations were included in the reliability analysis as "technical failures." For primary analyses, data from 45 patients completing all three techniques were used. Image quality was evaluated by three blinded radiologists (experience: 5, 10, 16 years). Statistical analysis included Friedman tests with Bonferroni correction (p < 0.0167).
Results: Median total examination times were significantly shorter for BM-MRCP (218 [48] seconds) compared to RG-MRCP (228 [56] seconds) and NT-MRCP (259 [53] seconds) (p < 0.05). BM-MRCP and RG-MRCP had comparable image acquisition times, both significantly faster than NT-MRCP (p < 0.05). BM-MRCP provided superior image quality for key anatomical structures (p < 0.05), higher SNR, and CNR compared to RG-MRCP and NT-MRCP (p < 0.05). Image contrast showed no significant differences (p > 0.05). Two patients experienced failures with RG-MRCP or NT-MRCP due to breathing issues, while BM-MRCP had no failures.
Conclusion: BM-MRCP significantly reduces examination times while achieving superior image quality and technical reliability. Its integration into clinical workflows enhances efficiency, reduces technician workload, and improves patient-centered imaging.
Critical relevance statement: BioMatrix-gating 3D-MRCP enhances imaging efficiency and diagnostic accuracy for the biliary and pancreatic duct systems. By reducing scan times and improving workflow, it supports patient comfort and compliance. Its simplicity and reliability also make it ideal for high-throughput clinical settings.
Key points: BioMatrix-triggered (BM)-MRCP shortens examination time, aiding patients with compliance or limitations. BM-MRCP offers superior image quality with reduced motion artifacts and higher clarity. BM respiratory sensors streamline workflows, boost reliability, and enhance patient comfort.
