7.0 T及以上的超高场MRI在骨骼肌肉系统的研究进展

Advances in ultrahigh-field MRI with 7.0 T and above in the musculoskeletal system

随着磁共振磁场强度的不断提升、扫描技术的智能化、扫描序列的创新及优化、新技术的脱颖而出,骨骼肌肉系统在磁共振成像的应用也是日新月异。7.0 T及以上的超高场MRI在骨骼肌肉系统成像中信噪比的提升尤为显著,超高分辨率图像有利于软骨、骨、韧带、肌腱、半月板等解剖结构细节的观察、病变信息的显示和呈现,从而提高诊断的特异性及敏感度。超高场MRI有利于高级功能成像的实现,提供了组织生化和代谢信息。本综述通过进一步总结超高场MRI在临床诊断、疾病监测及科学研究中的不足,提出未来可向优化成像序列、降低伪影和提高磁场均匀性等方向发展,为临床医生和研究人员提供超高场MRI应用的最新进展和前景,以促进超高场MRI在医学中的广泛应用和发展。

With the continuous improvement of magnetic field strength of MRI,intelligent scanning technology,innovation and optimization of scanning sequences,and new technologies,the application of MRI in skeletal and muscular system is also rapidly changing.The improvement of signal-to-noise ratio of ultra-high-field MRI of 7.0 T and above is particularly significant in the imaging of the skeletal muscular system,and the ultra-high-resolution image is conducive to the anatomical structure of cartilage,bone,ligaments,tendons,menisci,and so on.Ultra-high resolution images facilitate the observation of details of cartilage,bone,ligament,tendon,meniscus and other anatomical structures,the display and presentation of lesion information and advanced functional imaging,thus improving the specificity and sensitivity of diagnosis.This paper also discusses the shortcomings of ultra-high-field MRI in clinical diagnosis,disease monitoring and scientific research,which can be developed in the direction of optimizing imaging sequences,reducing artifacts and improving magnetic field uniformity in the future.The aim of this paper is to provide clinicians and researchers with the latest progress and prospects of ultrahigh-field MRI applications,in order to promote the wide application and development of ultrahigh-field MRI in medical imaging.
