磁共振功能成像对肝癌介入术后评估的进展

Application of functional MRI in evaluating hepatocellular carcinoma after interventional management:its latest progress

原发性肝细胞癌经介入治疗如何准确判定介入术后肿瘤坏死的程度及是否有肿瘤残留和复发,是广大学者关注的热点问题。MR具有无X线辐射性、较高的软组织分辨率、任意多角度和多参数成像的特点,尤其是近年来随着MR功能成像(f MRI)的不断成熟和应用于临床,使之能够更加灵敏地显示肝癌介入术后的组织成分变化,提供更多的量化评估参数。本文将重点概述f MRI在肝癌介入术后随访的进展。

How to accurately determine the degree of tumor necrosis and whether there is tumor residual and recurrence of hepatoeellular carcinoma （HCC） after interventional treatment, these issues have been the hot spots that have been discussed by the vast majority of medical scholars. Magnetic resonance imaging （MRI） has several advantages, such as no X-ray radiation, high soft tissue resolution, arbitrary multi-angle and multi-parameter imaging, etc. With the constant development of the functional MRI （fMRI） technique and its extensive use in clinical practice in recent years, the changes of tissue composition of HCC after interventional management can be displayed more sensitively and more clearly by this examination,thus, more quantitative assessment parameters can be provided for physicians. This paper aims to make a general review focusing on the recent progress in the clinical application of fMRI for the evaluation of HCC after interventional treatment
