Computed tomography is also known as CT scan. Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast.

It is not uncommon, for instance in the eldely where the risk of surgery may be much greater, when a brain tumor has features highly consistent with meningioma for the work up to stop after the ct or mri.

I had a CT scan of my brain and they found a lesion, my dr. Said it could be meningioma. Going 4 mri. What else could it be?
Falx calcification: This is likely to be a benign tumor. But MRI will see the tumor more clearly. It will also see the dura and the meninges if they are involved. In general ct scans always lead to another test and therefore are less useful. If you have a choice always choose the mri. You will save yourself radiation and money. ...Read more

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. ...Read more
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
