Can Ct Scan Detect Brain Tumor
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 not sensitive: Ct brain is a fast screening exam that is often used in the acute setting such as the emergency room. It is helpful in detecting obvious tumor and mass effect from the tumor. However, it is not sensitive in the detection of small tumor which does not produce mass effect or surrounding brain edema. Mri brain with and without contrast is the best imaging modality for detecting brain tumor. ...Read more

If CT scan w&wo contrast came back normal with no brain tumor found 2 years and 7 months ago what's my risk to have one now if I have new symptoms?
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 more
2 years and 8 months ago CT scan w&wo contrast ruled out a brain tumor now im worry again can a brain tumor grow that fast and cause symptoms im 27?
Had a CT scan for possible brain tumor how long for my dr to get results? If something was found would I have herd the same day?
Depends: Ct scan interpretations are usually available to the ordering physician the same day, at the latest the next working day. How quickly your physician informs you of the results is highly variable, unfortunately, and can't be predicted without knowing the habits of the individual physician you have. ...Read more
Had CT scan for brain tumor or bleed friday afternoon. Will I have to agonize all weekend? Is no news good news or was it just too late on a friday?
Don't assume: One would hope for a call, but lack of one doesn't mean anything--so don't read too much into it. Medical staff can drop the ball and leave patients in the dark, especially late on a friday afternoon. Definitely call the office monday morning to be sure. ...Read more
Yes: Ct scans can certainly on occasion miss a small tumor, especially when they are down in the posterior fossa at the base of the skull. Mri scans are more sensitive and less likely to miss a tumor, but even they can on rare occasions miss one that shows up later. These scans are read by human beings, and they can miss something that is there, too. ...Read more
Unlikely: A ct of the sinuses includes a portion of the brain, not all of it. So it could miss some areas. Hope this helps. ...Read more
Could radiation from mobile phones can cause brain tumor 10 or 20 years later? What about a CT scan its much more radiation?
No and probably no: Cell phones don't cause brain tumors. There's no biological basis, it's not the kind of radiation that mutates genes, the ongoing talk is driven by politicians, and the studies are such junk that one even had significantly more tumors on the opposite side. Ct scans may make a tiny contribution to glioma incidence but there's no proving in an individual case. ...Read more
Persistent headaches that last for a month everyday. CT scan 2 years ago, do I need to do again, im so scared of brain tumor..
Headache: Prompting a work up with CT scan 2 years ago that has returned again after a period of time is not likely due to a brain tumor in anyone yet alone a 25 year old. I would however do a scan if you were planning to have a spinal tap done to check for raised intracranial pressure due to pseudotumor cerebri. (Not uncommon in a 25 year old female) Check your iron, Vitamin A level and see a neurologist ...Read more

If I had a MRI oct2012 & cat scan in dec 2012 & both where normal should I b worried bout a brain tumor? Can a CT scan show a brain tumor n the brain
No worry: Very unlikely you would have a brain tumor, and not have it show up on the tests you mention. Very unlikely it would develop since then. ...Read more
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 more
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 :/
If a head CT scan with and without contrast ruled out brain tumor can I be sure that I don't have a brain tumor?
Why do you worry?: Cat scan is adequate to demonstrate even a modest size lesion, and seems reassuring. Yet, you remain focused and perhaps doubtful. Urge you contact a counselor and explore the underlying causes of your persistent concerns. Actually brain tumors are quite uncommon. ...Read more
Would a Brain MRI W/O Contrast & a CT Scan with and W/O Contrast show a brain tumor causing symptoms? Worried that it could have been missed.
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
