Brain Ct Scan Without Contrast
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
Ct scan dects brain aneurysms? Is it possible for a CT scan without contrast to reveal an unruptured brain aneurysm? Is the test meant to find that sort of thing?
Yes, it can: Did you go to an ER with H/A & they did a knee-jerk don't-sue-us CT scan which was normal? If you've had H/As for at least 3 years, the chances of finding a tumor on brain imaging are no greater than for someone with no history of H/A. Are your headaches of recent onset, relentless & worsening? If not, you can find something else to worry about, like the outcome of the 2016 presidential election. Read moreSee 1 more doctor answer
Had a fear of brain tumor for 7 months. Ct scan without contrast was clean. Would I be having severe symptoms by now if it was malignant?
Brain tumors aren't easily categorized into benign or malignant: Although the most aggressive type of brain tumor, glioblastoma, would likely be causing severe symptoms by now, there are other types of brain tumors that can be serious but not grow as quickly. The majority, however, would be associated with progressive symptoms during this time period. An MRI is the best test to evaluate potential masses in the brain. Read more
Would a CT scan without contrast show a brain tumor or evidence one was there? What are the chances it won't? Doc not concerned but my anxiety is :/
See long answer: Ct without contrast is largely indicated for acute hemorrhage or infarcts. It may not show more subtle tumors. Mri with contrast is much more sensitive in the correct clinical situation. Talk to your dr. To see if further imaging evaluation is appropriate. Read moreSee 1 more doctor answer
Some things: CT scan of brain without contrast shows basic anatomy of brain, gray white matter differentiation, ventricles, and physiologic calcifications. Ventricles enlarged/ hydrocephalus, mass effect with displacement of normal structures, some bleeding, abnormal calcifications in tumors or old subdural hematomas, fractures. CT with contrast adds enhancement of certain lesions not seen, hyper/hypo vascular. Read more

Last question I promise 2 years and 7 month ago I got a CT scan with and without contrast and it was clear? D I need to still worry about brain tumor
Most: 23 year old men do not need a head ct +/- contrast in the first place, and the exposure from the radiation when you do not need a scan is not worth repeating. Imaging is expensive and should only be done when necessary. You provide no information suggesting either ct or MRI is indicated. Read moreSee 1 more doctor answer

Is it possible for a CT scan of the head *without* contrast to show an unruptured brain aneurysm?
Can a CT scan with out contrast show if someone has a significant amount of blood in the brain from a ruptured anurysm?
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
