磁共振脂肪定量技术在腹盆部的应用及进展

Application and research progress of magnetic resonance imaging lipid detection techniques in abdomen and pelvis

目的总结常用的磁共振脂肪定量技术及其在腹盆部的应用及其研究进展。方法查阅国内外相关文献,对常用的磁共振脂肪定量技术的优缺点以及其在腹盆部器官或病灶中的应用与研究现状进行综述。结果脂肪选择性光谱空间激励技术、磁共振氢波谱技术和基于化学位移的水脂分离技术(Dixon&IDEAL)是目前常用的磁共振脂肪定量技术,能够无创、纵向评价腹盆部组织器官及病灶的相对或绝对脂肪含量,为异位脂肪沉积引起的疾病的早期诊断、治疗和随访提供可能。结论磁共振脂肪定量技术在评价组织器官的脂肪含量时具有重要的临床价值,目前常用的3种检查方法各有优势,其中改良的Dixon技术能更简便、较为准确地实现脂肪定量,具有更广阔的临床应用前景。

Objective To summarize applications and research progress of common magnetic resonance imaging lipid detection techniques in abdomen and pelvis. Method The latest domestic and foreign research literatures related to the applications and research progress of common magnetic resonance imaging lipid detection techniques in the abdomen and pelvis in recent years were collected and reviewed. Results The fat-selective spectral-spatial imaging, ~1H-magnetic resonance spectroscopy(~1H-MRS), and Dixon & IDEAL are three main magnetic resonance imaging lipid detection techniques, and they can estimate the fat content in the normal tissues and lesions noninvasively and longitudinally,which make the ectopic fat-induced diseases' early diagnosis, treatment and follow-up possible. Conclusion Magnetic resonance imaging lipid detection techniques have obvious clinical values in quantitative measurement of fat content, and each method gets its own advantage, especially modified Dixon, which is more convenient and accurate and shows an enormous potential in clinical practice.
