Ct Scan (Overview)

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 it is an estimate.

How are mr scan and a CT scan different?

Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density. Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor. ...Read more

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. This way the body is shown in slices, in any plane, usually axially, but ...Read more
