What Are The Risks Of A Brain Ct Scan
Very safe in general: A plain ct scan really only caries the risk of a fairly modest radiation exposure, so we typically only start to worry about this for people who get many cts in a single year. If it is being done with intravenous contrast, then there is a risk of allergic reaction to the iodine, as well as some risk of kidney damage in those with underlying kidney risk factors (eg elderly, diabetes). ...Read moreSee 1 more doctor answer
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. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Risk vs Benefit: The main risk is that a small amount of radiation is used during the procedure which can slightly increase the risk of developing cancer in the future. The real question is why is the CT being ordered? If the benefit of diagnosing a problem with CT is greater than the miniscule risk of developing cancer in the future, get the CT. Remember there is also a risk of missing a disease without the CT ...Read more
Minimal: A cat scan is a fairly safe procedure. A single exam to a part of a body does not have significant risk as far as radiation exposure. An exam using IV contrast has a slight risk for contrast reaction. Serious reactions are quite rare. If you have a significant allergic history(significant allergic response to multiple things) your risk is slightly greater. ...Read moreSee 1 more doctor answer

I have anxiety and am going to see a neurologist . I had a brain CT scan last year and it was clear . Will I need another one?
I had a brain ct scan in the ER which I feel was unnecessary. I deeply regret this and I'm afraid I'll get brain cancer from this scan. Please help.
Yu're unnecessarily: One CT scan does not cause anyone cancer. it takes more than 10 CT scan before such a thought should come to your mind. Medical use of X-rays/CT scans(done once a year or so) is safe. So quit worrying about this incident.. Your brain will be fine for a long long time! ...Read more
Would a CT scan show cysts in the brain? If so, would a dr mention them if seen during a brain CT scan after a head injury from a car accident?
It would: Ct scans of the brain can provide detailed information about brain pathology, thus providing more information related to injuries and/or diseases of the brain. Findings could bleeding, brain injury and skull fractures in patients with head injuries. However, MRI will be more precise for details of soft tissue. ...Read more
I'm 18. I ordered a brain CT scan for the 2nd time for dizziness, should I go ahead and do it or call back and try to get an MRI instead?
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
