3D CEST 成像

3D CEST imaging

Chemical Exchange Saturation Transfer (CEST) is a magnetic resonance imaging technique that detects low-concentration metabolites by saturating their exchangeable protons and observing the signal loss in bulk water. 3D CEST imaging extends this by acquiring volumetric data in three dimensions, improving spatial resolution and coverage for detailed tissue characterization. / 化学交换饱和转移（CEST）是一种磁共振成像技术，通过饱和可交换质子并观察体液中信号损失来检测低浓度代谢物。3D CEST 成像通过在三个维度上采集体数据，提高了空间分辨率和覆盖范围，以实现详细的组织表征。
