Ct scan can reveal a brain tumour and an MRI showed nothing. Which to believe?

Strange. Usually an MRI is more sensitive (better) at detecting rumors than CT. Did the radiologist who read the MRI have access to the CT and its report? It is possible that something that was thought to be a mass on a CT turned out not to be one on MRI. .

If im in the ER and they wanna check for a brain tumor by doing a CT scan. Can I request an MRI without contrast instead or is that not an option?

Yes/No. A ct scan has the advantage of being fast (and cheap from the insurance companies standpoint) and gives a good enough resolution as a screening test. You can request an MRI without contrast, however, if something is found, you need to get another MRI scan which is a longer, and more expensive, time commitment. Read more...
Depends . On symptoms. Ct head good to do first. Then MRI with and or without contrast as indicated. See radiologyinfo.Org. Each test meets acr appropriateness criteria. Read more...
Reason for asking? First, hospitals aren't hotels. You're a patient, not a guest. Most choices aren't yours to make. Second, why would "they" "wanna" check for a brain tumor in a 19-year-old? Maybe YOU wanna check? It's not impossible, but the chances are mighty remote that "they'd" be concerned about it. I suspect it's safe to stop worrying, or failing that, at least find something else to worry about. Read more...

Had CT scan MRI both of brain, neurological exam, EEG and evoked potential test all negative 1 year ago. Should I still worry about a brain tumour?

Probably not. Given that your exams were negative a year ago, it is unlikely that you would have a brain tumor if your symptoms have not changed. However, consider seeing your doctor if you are having any worsening or new symptoms and he or she will determine if it is appropriate to repeat any of the exams. Read more...
Not really. Brain tumors are rare (less than 5% of all tumors). If all those tests are normal, and you have no symptoms, a brain tumor is extremely unlikely. Read more...
Comment. Sounds like numerous reassuring studies provided only transient support, and you still are worrying about a brain tumor. Suggest you explore why you have this intense concern, and suspect you can learn to control your fears. Some counseling will be of benefit. Read more...

Will a cat scan of my head rule out MS or a brain tumor better than mri? Had one before but am having another one due to vertigo. I'm 18.Am I in danger?

No. Mri is by far the test of choice for ms. Either way will detect brain tumors, but actual better picture of the tumor itself with a mri. There is no danger to mri. Cat scans have radiation, but your doctor will guide you in consultation with a radiologist as to which test is most appropriate for your symptoms. Read more...
MRI. Mri is more sensitive for detecting subtle abnormalities such as ms or small tumors. Preferrably an MRI with contrast. You should discuss with a neurologist before getting the scan. Read more...
