摘要

振荡梯度自旋回波序列能够以较短的扩散时间测量扩散权重，并能提供内部结构的指示。我们报告了两例脑脓肿，其中表观扩散系数(ADC)值在短扩散时间比长扩散时间更高。脑脓肿中ADC的扩散时间依赖性不仅表明底物黏性，而且表明病变内部结构限制了扩散。

Time-dependent Diffusion in Brain Abscesses Investigated with Oscillating-gradient Spin-echo.

Oscillating-gradient spin-echo sequences enable the measurement of diffusion weighting with a short diffusion time and can provide indications of internal structures. We report two cases of brain abscess in which the apparent diffusion coefficient (ADC) values appear higher at short diffusion times in comparison with those at long diffusion times. Diffusion time dependence of the ADC in brain abscesses suggests not only substrate viscosity but also restricted diffusion due to the structure within the lesions.
