In this article, functional magnetic resonance (MR) imaging techniques in the abdomen are discussed. Diffusion-weighted imaging (DWI) increases the confidence in detecting and characterizing focal hepatic lesions. The potential uses of DWI in kidneys, adrenal glands, bowel, and pancreas are outlined. Studies have shown potential use of quantitative dynamic contrast-enhanced MR imaging parameters, such as K(trans), in predicting outcomes in cancer therapy. MR elastography is considered to be a useful tool in staging liver fibrosis. A major issue with all functional MR imaging techniques is the lack of standardization of the protocol.
本文讨论了腹部的功能磁共振（MR）成像技术。扩散加权成像（DWI）提高了检测和鉴别肝脏局灶性病变的可信度。概述了DWI在肾脏、肾上腺、肠道和胰腺中的潜在应用。研究表明，定量动态对比增强MR成像参数，如Ktrans，在预测癌症治疗结果方面具有潜在用途。MR弹性成像被认为是肝脏纤维化分期的有用工具。所有功能MR成像技术的一个主要问题是缺乏方案的标准化。
