在过去 5 年中，平衡稳态自由进动 (SSFP) 对于诊断和功能成像变得越来越重要。平衡 SSFP 具有两个独特的功能：它提供非常高的信噪比和 T2/T1 加权图像对比度。本文重点介绍平衡 SSFP 的物理原理、信号形成以及由此产生的特性。讨论了对比度修改的机制、最近的临床应用以及该技术的潜在扩展。
During the past 5 years balanced steady-state free precession (SSFP) has become increasingly important for diagnostic and functional imaging. Balanced SSFP is characterized by two unique features: it offers a very high signal-to noise ratio and a T2/T1-weighted image contrast. This article focuses on the physical principles, on the signal formation, and on the resulting properties of balanced SSFP. Mechanisms for contrast modification, recent clinical application, and potential extensions of this technique are discussed.
