CT scans and MRIs are called imaging tests because they take pictures, or images, of the inside of the body. Many people who have very painful headaches want a CT scan or an MRI. They want to find out if their headaches are caused by a serious problem, such as a brain tumor.
There's no specific test to diagnose migraines. For an accurate diagnosis to be made, a GP must identify a pattern of recurring headaches along with the associated symptoms. Migraines can be unpredictable, sometimes occurring without the other symptoms. Obtaining an accurate diagnosis can sometimes take time.
Medical professionals will not use a CT scan to diagnose migraine headaches. If a person is experiencing migraine, a CT scan will rarely show the cause of the pain. However, a doctor may order a CT scan or similar imaging test to rule out other causes of a person's headaches.
CT scans show a slice, or cross-section, of the body. The image shows your bones, organs, and soft tissues more clearly than standard x-rays. CT scans can show a tumor's shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient.
Many people who have migraines find that over-the-counter painkillers, such as paracetamol, aspirin and ibuprofen, can help to reduce their symptoms. They tend to be most effective if taken at the first signs of a migraine attack, as this gives them time to absorb into your bloodstream and ease your symptoms.
But a migraine that lasts for more than 72 hours is called status migrainosus. To treat it, you may need to go to the hospital to get help relieving the pain and dehydration from vomiting.

However, they did point out that some individuals with significant psychiatric co-morbidities might benefit from the reassurance of having a normal scan.
Neurosurge ons, on the other hand, often rely on neuroimaging of patients with non-specific symptoms as a way to diagnose brain tumors. 1,2. To cut through this lack of clarify, the American Headache Society (AHS) recently released an updated, evidence-based guideline. for neuroimaging in patients with migraine.
Most experts agree that neuroimaging should be used sparingly and with caution when diagnosing and treating migraine. Yet, when to use and when not to use neuroimaging has long been a vexed issue. It’s not always clear when the risks of neuroimaging are justified. Those risks include increased patient anxiety, the need for further testing which can ...
Despite the complexities and limitations in the evidence, the results of the review were clear. “Migraine alone is not a risk factor for an abnormal MRI or CT in the absence of risk factors. [A patient with] migraine alone without anything else, has no greater chance of having imaging abnormalities than [a patient without] migraine,” Silberstein said. “So if you took 100 people off the street with no problems and a hundred people with migraine, the imaging would be the same.”
Migraine. Migraines are a common primary headache disorder and can present variably. Typically they consist of debilitating headaches, accompanied by an aura in one-third of patients.
Migraines without aura usually consist of a headache that lasts 4 to 72 hours that is typically unilateral, moderate to severe and has a pulsating quality. The headache is often associated with photophobia, phonophobia and nausea and is worsened by physical activity 7 .
In the vast majority of cases, MRI is normal. In hemiplegic migraines, venous dilatation can be seen on SWI MIP images contralateral to the hemiparesis, although this is not typical 3. Changes in cerebral perfusion have also been described 3 .
The doctor will look for signs and symptoms of an illness that may be causing the headaches, such as: Neurological tests focus on ruling out diseases of the brain or nerves that may also cause headaches and migraines. The vast majority of headaches turn out to be benign in nature.
Balance problems, falling. Dizziness. Vision changes (blurry vision , double vision, blind spots) Neurological tests focus on ruling out diseases of the brain or nerves that may also cause headaches and migraines. The vast majority of headaches turn out to be benign in nature.
Some of the tests look for a physical or structural abnormality in the brain that may cause your headache, such as: Tumor. Brain abscess (an infection of the brain) Hemorrhage (bleeding within the brain) Bacterial or viral meningitis (an infection or inflammation of the membrane that covers the brain and spinal cord)
What other symptoms or warning signs occur with a headache (such as weakness, nausea, sensitivity to light or noise, appetite changes, changes in attitude or behavior) How often you get headaches.
It may also be recommended if a CT scan does not show definitive results. In addition, an MRI scan is used to evaluate certain parts of the brain that are not as easily viewed with CT scans, such as the spine at the level of the neck and the back portion of the brain. Sinus X-ray.

However, as it is so sensitive, there are often abnormal findings unrelated to the headache that may lead to further testing. The most common abnormalities are small spots in the brain that may be mistaken for Multiple Sclerosis.
new headache in people over age 50. no better with prescribed medicine. persistent headache after head injury. persistent fever. Brain imaging will often be ordered based on a headache that does not meet criteria for migraine, or has features that in the opinion of the provider is worrisome.
