Abstract

OBJECTIVE

The purpose of this article is to review abdominopelvic applications of diffusion-weighted imaging (DWI), discuss advantages and limitations of DWI, and illustrate these with examples.

CONCLUSION

High-quality abdominopelvic DWI can be performed routinely on current MRI systems and may offer added value in image interpretation. Particularly in unenhanced MRI examinations, DWI may provide an alternative source of image contrast and improved conspicuity to identify and potentially characterize pathology. DWI is a powerful technique that warrants implementation in routine abdominal and pelvic imaging protocols.

摘要

目的

本文旨在综述扩散加权成像（DWI）在腹盆部的应用，讨论 DWI 的优势和局限性，并通过实例加以说明。

结论

目前在 MRI 系统上可常规进行高质量的腹盆部 DWI，可为图像解读提供附加价值。特别是在未增强 MRI 检查中，DWI 可能提供一种替代的图像对比源，并提高对病变的显示和潜在特征的能力。DWI 是一种强大的技术，值得在常规腹部和盆腔成像方案中实施。
