磁共振弹性成像在腹盆部肿瘤中的研究进展

Research progress of magnetic resonance elastography in abdominal and pelvic cancer

肿瘤力学特性与肿瘤侵袭、进展密切相关,准确评估肿瘤组织硬度对于肿瘤的检测、鉴别诊断、诊疗规划及预后评估具有重要意义。磁共振弹性成像(magnetic resonance elastography,MRE)能量化组织力学特性,无创定量评估组织硬度,进而间接反映组织纤维化程度。本文将对MRE的基本原理、技术发展及其在腹盆部肿瘤中应用的研究现状进行综述,旨在为未来的研究提供新思路,推进MRE的不断成熟,辅助指导临床精准诊疗。

The mechanical properties of tumors are closely associated with tumor invasion and progression,and the accurate assessment of tumor tissue stiffness holds significant importance in tumor detection,treatment planning,and prognosis evaluation.Magnetic resonance elastography(MRE)enables the quantification of tissue mechanical properties,noninvasive and quantitative evaluation of tissue stiffness,as well as indirect reflection of the extent of tissue fibrosis.This article provides a review on the fundamental principles,technical advancements,and research status of MRE in abdominal and pelvic tumors with an aim to offer novel insights for future investigations while promoting the continuous maturation of MRE technology to aid in guiding clinical precision diagnosis and treatment.
