Ct Scan Brain Results
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 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
Eye of Beholder:
The "eye ball" observation of "volume loss for age" is extremely subjective with much intra and interobserver variation. That means readers often don't agree and are sometimes not even consistent when the same reader re-examines an image twice.
Computer programs are being developed to analyse brain volumes accurately and precisely but are not in general clinical use yet.
My advice, don't sweat it. ...Read more
I recieved brain CT scan results they say incomplete fat suppression can some one please explain this. Thanks for your reply?
Technical finding: I am going to assume that you had an MRI rather than ct. Incomplete fat suppression has nothing to do with anything in your body or you as a patient. "fat suppression" is a technique used in MRI to make the images appear a certain way. It is often technically difficult to obtain complete suppression so we as radiologists refer to this finding as "incomplete fat suppression." I hope this helps. ...Read more
I had a CT scan of my brain. The results read I had small lucunar infarct left basal ganglia small vessel ischemic disease... What do I have? It started with a headache on my right temple for the last 6 months, doctor sent me to physical theapy, but did
Small strokes: A small lacunar infarct refers to a stroke from occlusion of a small blood vessel. Small vessel ischemic disease refers to a chronic process whereby the small blood vessels become smaller and smaller over time and cause tiny strokes in certain brain tissues. Typical risk factors are chronic hypertension, smoking and diabetes mellitus. These small strokes can be significant when they accumulate. ...Read more
I had a CT scan for my brain due to headaches it has been just over 2 weeks and I have not got my results?
Too long: You should call the doctor who ordered the test to find out the result. ...Read more
I had a CT scan today. The results say I have a perivascular space on base of brain, on the right. What does this mean? Thank you.
Means you check out: It's a benign finding and in fact quite normal in the majority of people. ...Read more
Insomnia: Insomnia is related to the brain, but MRI scan will not delineate "why" you can't sleep. I suggest consulting with a psychiatrist and/or sleep medicine physician, insomnia can result from primary sleep disorders like sleep apnea, and also from psychiatric conditions like depression and anxiety disorders. Effective reatment is possible only with a thorough evaluation first. Best wishes. ...Read more
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
Echocardiogram results indicate an avm. Ct scan of chest and MRI & mra of brain are still negative. Where else might the avm be?
Anywhere: Arteriovenous malformation or avm is an abnormal connection between arteries and veins, bypassing the capillary system. The congenital vascular anomaly occurs commonly in the central nervous system, but can appear in any location. Although many avms are asymptomatic, they can cause intense pain or bleeding or lead to other serious medical problems. ...Read more
Echocardiogram results indicate an avm. CT scan of chest and MRI & mra of brain still negative. Where else might the avm be, what does thi mean?
Anywhere: AVM's can be anywhere including the brain, lungs, intestines. Dr. Rich White at Yale runs the world class HHT center for patients with AVM's in multiple vascular beds. ...Read more
Possibly: At your age, deep white matter ischemic changes are not common. There are a few possibilities: either you have engaged in activities that have harmed your brain (ie- excessive alcohol intake or other toxins), or you are predisposed to small vessel disease (common in diabetics) or it is possible that a demyelinating condition like ms can cause this appearance. I would recommend seeing a neurologist. ...Read more
At age 33, I had to have a CT scan followed by MRI. The results-had Cerebral Atrophy. Is this a concern for me and should I worry?
My CT scan result shows - right frontal lobe subcortical white matter tiny chronic infarct- and mild cerebral atrophic changes.?
My 11 months nephew had seizures. His EEG test came out normal, CT scan result reports he has mild cerebral and cerebellar atrophy, how it happened?
About EEG, seizure: If there is atrophy (means smaller than normal) please see a pediatric neurologist. Eeg's can be normal in the context of seizures for many reasons. If they are abnormal, they are often helpful, but treating your nephew clinically is most important, and eeg's are a first step to diagnosis with prolonged studies or other types of eeg's as a next step. ...Read more
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 x ray radiation in a CT has no measurable or known effect on neural tissues. 1) dose is way too low and 2) nerves are relatively radioresistant since the cells don't reproduce very fast, if at all.
There is a theoretical risk of cataracts and cancer years later, but this is incredibly small esp. For a single scan and controversial anyway. ...Read more
Of what?: Patchy areas means that there area scattered areas of something on the scan. Usually in a head ct it will be patchy areas of white matter low attenuation/density. This finding is usually associated with aging and vascular disease but if it is in you and you're 26 then it is not normal aging and could be something like multiple sclerosis. Find out what it actually says though. ...Read more
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
Depends: It depends on what your symptoms are but it is a very useful test. ...Read more
Sounds like it.: If the CT was a CT of your brain and the doctor said it looked good, I would assume that it was OK. That is, good=OK. What he really meant and what you really mean by OK remains a mystery to me. Please check with them to make sure - Get a copy of the report so you can see specifically what "good" is. ...Read more
Holding still 30 sec: Not much. Lying still on a ct table for 30 sec while a 3d xray of your head is generated with a rotating xray camera. ...Read more
How dangerous is CT scan of brain in a young adult? Wil it cause any problems in the future? Is it a risk factor for any disease?
CT scan: Ct scans are safe for most people, and the doctors weigh the need for this information vs the exposure to radiation, etc. If the scan includes contrast ("dye") there may be reactions to this -- but most people are not allergic. Your doctors should be checking your history and be ready for any possibility. Please discuss your concerns with the doctors who already know you. ...Read more
Very safe in general: A plain ct scan really only caries the risk of a fairly modest radiation exposure, so we typically only start to worry about this for people who get many cts in a single year. If it is being done with intravenous contrast, then there is a risk of allergic reaction to the iodine, as well as some risk of kidney damage in those with underlying kidney risk factors (eg elderly, diabetes). ...Read more
Nope: Sometimes you can see evedence of bleeding. With traumatic brain injury sufficient to cause changes on ct typically survival is markedly reduced. Certain types of MRI done at the right time following a brain injury can sometimes show evidence of cerebral contusion. Much of the damage done with traumatic brain injury is microscopic (too small even with diffuse axonal injury) to be seen on mri. ...Read more
