A member asked:
Can you tell me how contrast make cancer stand out in a ct scan ?
A doctor has provided 1 answer
Vascularity: The contrast makes blood vessels whiter to stand out. Most tumors are hypervascular, they have more blood vessels. This makes them easier to see with contrast. Some tumors are not hypervascular and can be seen because they are less white than the surrounding tissues. Otherwise an MRI may be required to see the tumor.
