Ct scans: results. I am doing a biology test?

In a ct scan of the lungs, does a tumour show up as white or black, and what does TB show up as. would appreciate any help please..

it will all depend on the view you get. some are what you may understand to be "reverse negatives," where a tumor would show up as white or gray, in a normal x-ray view, but they've reversed it and the tumor may show up as a black mass. you need to leave the interpretation of the scans to the radiologists though. let them show you the scans and explain what they find and that would be your best education on the subject without having formal training in the medical field.

i want to see that a tumur will come out white, not too sure
