摘要

现代磁共振成像扫描仪的梯度性能不断提高，大大缩短了临床可用的脉冲梯度自旋回波（PGSE）序列可达到的扩散和回波时间。ADC 被认为是区分正常和异常脑组织以及进行后续治疗的重要诊断指标。

Normal Brain and Brain Tumor ADC: Changes Resulting From Variation of Diffusion Time and/or Echo Time in Pulsed-Gradient Spin Echo Diffusion Imaging.

Increasing gradient performance on modern magnetic resonance imaging scanners has profoundly reduced the attainable diffusion and echo times for clinically available pulsed-gradient spin echo (PGSE) sequences. This study investigated how this may impact the measured apparent diffusion coefficient (ADC), which is considered an important diagnostic marker for differentiation between normal and abnormal brain tissue and for therapeutic follow-up.
