摘要
常规1.5T与3.0T MRI已广泛用于腹部成像,但在早期功能成像及亚解剖结构分辨方面仍受限。随着超高场MRI技术在扫描流程智能化、序列创新优化方面的发展,5.0T MRI在肝脏、胰腺及肾脏成像应用逐渐增多。5.0T MRI具有更高的图像信噪比、空间分辨率和组织对比度等特点,技术优势日益凸显。本文对5.0T MRI在腹部成像中的最新研究进展进行综述,探讨其在腹部实性器官中的应用潜力、临床价值和技术挑战。尽管5.0T MRI技术仍面临一些难题,其在腹部成像中的临床应用前景广阔,有望为临床诊断流程及治疗策略提供更为丰富的决策依据。
Conventional 1.5T and 3.0T MRI have been extensively implemented for abdominal imaging;nevertheless,their capacity for early functional assessment and sub-anatomical delineation remains suboptimal.Recent advances in ultra-high-field technology—characterized by intelligent acquisition workflows and innovative sequence design—have progressively expanded the clinical deployment of 5.0T MRI for hepatic,pancreatic,and renal applications.Capitalizing on superior signal-to-noise ratio,enhanced spatial resolution,and improved tissue contrast,5.0T systems now offer a compelling technical advantage over lower-field counterparts.This review synthesizes the latest evidence on 5.0T abdominal MRI,critically appraising its potential applications,clinical value,and prevailing technical challenges in solid abdominal organs.Despite unresolved hurdles,5.0T MRI is poised to enrich diagnostic workflows and therapeutic decision-making in abdominal radiology.
