Compared to CT scans,MRI scans are more useful for differentiating gray matter from white matter because:
A) MRI acquires the images at a higher resolution compared to a CT scan.
B) tissues with high water content generate a different MRI signal from that of tissues with low water content.
C) of differences in oxygen content between gray matter and white matter.
D) All of the answers are correct.

Question

Quizplus · Accepted Answer

Tissues with high water content generate a different MRI signal from that of tissues with low water content, which allows for differentiation between gray matter and white matter. CT scans do not have this level of tissue specificity. Additionally, MRI acquires the images at a higher resolution compared to a CT scan, which further contributes to its ability to differentiate gray matter from white matter. However, choice C is not accurate as the differences in oxygen content between gray matter and white matter are not sufficient for reliable differentiation on their own.
