The advancement of functional magnetic resonance imaging in tumor diagnosis and appreciation of curative effects of liver disease

磁共振功能成像在肝脏应用主要包括弥散成像、灌注成像、波谱显像三方面。目前,弥散成像和灌注成像已广泛应用于肝脏肿瘤和弥漫性疾病的诊断、鉴别诊断和治疗后疗效评价。波谱分析从探测活体组织化合物浓度入手,为肝脏疾病的更早期、更特异诊断和疗效监测方面提供了新方法。本文综述了近年来磁共振功能成像在肝脏疾病的诊断及疗效评价方面的应用进展。

Functional magnetic resonance imaging （fMRI） includes diffusion-weighted imaging （DWI）, perfusion-weighted imaging （PWI）, and MR spectroscopic imaging （MRS） in hepatic lesions. DWI and PWI were widely used in diagnosis, differentiating, and evaluating the prognosis of liver neoplasm and diffuse lesions. Through detecting chemical concentration in vivo MRS provides a new method for earlier and specific diagnosis and monitoring curative effects of liver lesions. This article reviewed fMRI advancement in tumor diagnosis and appreciation of curative effects of liver disease.
