Question

question 2

sites of blockage resulting from arteriosclerosis are usually revealed by:

a ct scan
a pet scan
an fmri image
a nissl - stained brain section
an angiogram

Explanation:

CT scan shows anatomical structures but not specifically blockages from arteriosclerosis. PET scan shows metabolic activity. fMRI shows brain activity. Nissl - stained brain section is for cellular details. Angiogram is specifically used to visualize blood vessels and blockages (like those from arteriosclerosis) by injecting a contrast medium.

Answer:

an angiogram
