What does a CT scan of the head and neck show?

These can have symptoms similar to those of vascular dementia. A CT scan may also show a stroke or an MRI scan may show changes such as infarcts or damage to the white matter.

Can a CT scan miss a brain bleed?
First, CT scans are relatively poor at identifying soft tissue injuries. As a result, CT scans on average miss 10–20% of abnormalities that an MRI would detect. Second, TBIs can take time to develop on a physical level. A microscopic brain bleed might not appear on a CT scan for hours or even days, for example.
How long does a CT scan of the head take?
The technologist will always be able to see and hear you during your exam. This procedure usually takes approximately 15 to 30 minutes.
How bad is a CT scan for you?
At the low doses of radiation a CT scan uses, your risk of developing cancer from it is so small that it can’t be reliably measured. Because of the possibility of an increased risk, however, the American College of Radiology advises that no imaging exam be done unless there is a clear medical benefit.
Do you get CT scan results immediately?
CT Scans are one of the few tests where your doctor or radiology can receive test results nearly immediately. Your radiologists will review and interpret your CT scan as soon as it’s completed.
