扩散峰度成像（DKI）是近年发展起来的一项新的磁共振功能成像技术，它能反映更复杂的水分子的扩散，其多个峰度指标在良性肿瘤中较低而在恶性肿瘤中较高，并可随着肿瘤的恶性程度增加而增高。虽然目前DKI在肿瘤方面的研究仍相对较少，但从国内外学者已经完成的一系列实验中我们可以发现DKI的重要价值，随着DKI技术的进一步成熟与发展，我们相信其必将为临床工作做出更多贡献。
Abstract
DKI, a new magnetic resonance imaging technology, which can reflect the more complex diffusion of water molecules is developed in recent years. Multiple kurtosis indexes of DKI are lower in the benign tumor while higher in the malignant tumor. Moreover, these kurtosis indexes can be increased with tumor malignant degree increased. Although the number of DKI in cancer research is relatively small, we still can find the important value of DKI from a series of experiments done by domestic and foreign scholars. With the further maturity and development of DKI technology, we believe that it will make more contributions to clinical work.
