Abstract
We propose that a simple but reasonable initial interpretation of brain and spinal cord MRI can be made by considering whether signal intensity is white or black or gray on precontrast T1-weighted and T2-weighted pulse sequences. We have formulated this task as a 2 x 2 table.
摘要
我们提出，通过考虑在预对比 T1 加权和 T2 加权脉冲序列上信号强度是白色、黑色还是灰色，可以对脑和脊髓 MRI 进行简单但合理的初步解读。我们将此任务表示为一个 2x2 表。
