Ct Of Brain (Overview)

CT (a type of xray scan) of the brain normal is a test result in which a CT scan of a person's brain does not show any abnormal problems in the brain. Only some brain problems can be detected by a CT scan.

What is a CT scan (brain) used for?

See the brain, skull: While xrays show the bones, a ct is sensitive enough to see the brain and its structures. Ct is vers useful to see blood, abnormal fluid collections, masses, areas of old or subacute stroke. The skull, sinuses, scalp and facial bones, eyes, mouth are also seen. Mri is even more sensitive for visualization of the brain and other soft tissue structures and may be required if the ct is positive. ...Read more

The CT scan brain results suggest that they a probability of demyelinating disease. Is this normal at my age?

The CT scan brain results suggest that they a probability of demyelinating disease. Is this normal at my age?

No, but...: Mri scans are more sensitive and specific for demyelination than ct scans. This means that not only are mris better at finding it when it's present, but not finding it on an MRI means that it's almost certainly absent. "suggestive" findings of demyelination on a brain ct that is not seen on an MRI are generally treated as "false-positive." that gets into the science of testing (no room here). ...Read more

Ct of brain shows multiple old right and a single left chronic thalamic lacunar infarcts measuring up to 1 CM noted. What does all that mean?

Multiple CVA: Basically the ct reveals multiple infarcts or areas of the brain that have been damaged by lack of blood flow. This could have been caused by blood clots blocking arteries in the brain or areas of plaque in blood vessels causing blockage. ...Read more

Can CT see brain atrophy from alzheimer's or dementia?

If advanced, yes: If alzheimer's or other dementia is far enough advanced, then ct can show cortical atrophy and enlarged ventricles. However, functional brain changes can be going on for a long time before anatomical changes show up. ...Read more

Can CT of sbdomen see aortic aneurysm? My doctor ordered a CT but have had 3 CT on brain. Is it safe to have another?

Can CT of sbdomen see aortic aneurysm? My doctor ordered a CT but have had 3 CT on brain. Is it safe to have another?

Yes ; Yes: The ct scans of your head have no real affect elsewhere. It's safe to have the abdominal one. The ct is the best method to see the overall size of an aneurysm, but it can underestimate blockages if not done with IV contrast to see the lumen (the opening inside). After you know you have an aneurysm, us may be used to follow it. ...Read more

Can TMJ cause facial numbness/lack of sensation? CT of brain normal, have seen a neurologist who think it may beTMJ.

Can TMJ cause facial numbness/lack of sensation? CT of brain normal, have seen a neurologist who think it may beTMJ.

Secondary TMJ.: The facial nerve (Cranial nerve VII) courses thru the temporomandibular junction (TMJ). Inflammation or pressure in that region can disrupt the nerve. Usually it isn't due to misalignment of the jaw/mandible with the skull) - that causes a "clicking" sensation when opening/closing the mouth. However, stranger things have happened. Evoked potentials (EMG/NCS) of the facial nerve may help diagnosis. ...Read more

MRI & CT of brain & nerves are normal, but walking causes an electric shock like feeling on the heels as they touch the floor & can only tip toe?

Plantar Fasciitis: Hi, I believe you are suffering from Plantar Fasciitis a condition in which the ligament in your heel is inflamed therefore the bottom of your foot hurts with walking or standing, the main treatment is stretch exercise, but anti inflammatory medication could help. If these measures failed then your orthopedic doctor might inject your heel with steroid, search for the home exercise on google. ...Read more

I started having seizures. Had MRI & CT scan brain. Eeg normal. Continue to have numerous seizures. Have suffered to shoulder pain for some time.

2B brutally honest..: Your docs didn't level with you or you're in denial. "functional szs" aka nonepileptic szs or pseudoseizures are psychiatric not neurological. Of course MRI & eeg were normal. You're not having true epileptic seizures. Instead of frankly addressing the underlying psych issue, you're distracting yourself (& others) with "szs." face the real problem squarely & you won't need to act out with szs.. ...Read more

Have had 6 CT of brain & 1 CTA of brain due to concussions over the years. (10 years). One sinus CT when I was young. What are my cancer risks?

Low: More than if you did not have the ct scans, but still low overall. You should note that radiation is cumulative, and ask for a non-ionizing radiation test if possible for the future, such as an MRI. Hope this helps! ...Read more

Normal CT of brain within past six mths. Would a symptomatic brain tumor develop quickly since then? Also, normal eye exam and visual acuity tests

Unlikely: Unless it is from somewhere else and it is infiltrating type to the tissues. Imagine a speck of tissue not seen six months ago by ct scan. The usual doubling time of a tumor in volume is 3 months. For it to grow and cause symptoms, it has to have been big enough to be seen 6 months ago. ...Read more

"Short fluid level in the maxillary sinus" on CT of brain. Could this point to a CSF leak? I had chronic post nasal drip and sinus issues for years.

"Short fluid level in the maxillary sinus" on CT of brain. Could this point to a CSF leak? I had chronic post nasal drip and sinus issues for years.

Much more likely: That your chronic inflammation of the sinus has blocked drainage & caused mucus to be retained in your maxillary sinuses. Seek evaluation by an ENT specialist. This would not necessarily explain your unwanted weight loss, especially if the fluid is not chronically infected. ...Read more

Neck cracking/popping, forehead/scalp tingling, the result of pinched nerves in neck from bulges at C5-C6 and C6-C7 via neck MRI? MRI's and CT's of brain were normal. Thanks.

Neck cracking/popping, forehead/scalp tingling, the result of pinched nerves in neck from bulges at C5-C6 and C6-C7 via neck MRI? MRI's and CT's of brain were normal. Thanks.

Does not correlate.: The disk bulges at C5-C7 should affect your arm & neck, not the forehead & scalp. Many people live their ENTIRE LIVES with bulging disks & don't complain of any pain, so MRI or CT scan to "diagnose" bulging disks is actually a gross misuse of imaging. Talk to your doctor or a neurologist about your symptoms to undergo accurate testing. Or use HealthTap Prime. Good luck to you; hope you find cause. ...Read more

Ordered CT scan brain MRI for lumbar spine after fall stairs lft leg has been numb 3yr prior to stairs spine not bad brain chronic microvascular ishemic white matter disease ms? Autoimmune?

Ischemic Brain: Not likely. At your age, the vascualr ischemia is more apt to be due to chronic high blood pressure or diabetes. It is important to follow up on this with your doctor to avoid small lesions called "lacunar" infarcts. Often, medication can be prescribed which will improve your micro vascualr integrity and avoid further damage. ...Read more

Clear head CT and brain mri, blood pressure normal, why do I have a constant headache that won't go away : (?

Benign: The commonest cause of a benign headache is a muscle contraction, (tension) headache. The next most common is a migraine. Then sinus headache. I see you take sudafed - this may actually be contributing. Speak with your doctor and consider analgesics and muscle relaxant/anxiolytics. ...Read more

Computed Tomography (Definition)

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
