Both signal intensity on trace images and apparent diffusion coefficient measurements on mapped images evolved rapidly on serial diffusion-weighted sequences in a case of pyogenic brain abscess that was monitored primarily by MRI before a biopsy was performed. Considering only the signal intensities on the trace images would have led to an underestimation of the intrinsic tissue changes.
在一例化脓性脑脓肿患者中,在进行活检之前主要通过MRI监测,其追踪图像上的信号强度和映射图像上的表观扩散系数测量值在连续扩散加权序列上迅速演变。仅考虑追踪图像上的信号强度会导致对内在组织变化的低估。
