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

My head was feeling numb. I had a cat scan which showed nothing. Could I be having a mini TIA stroke?

No: Numbness in the head may not be tia/ you may have to look for other causes such as neuropathy, anemia, B12 deficiencies etc. You need a thorough evaluation with a neurologist. ...Read more

Why would a CT scan obtained the 3rd day after a lacunar stroke be normal?

It is possible: Sometimes a lacunar stroke does not appear on CT - at least for a small lacunar stroke. An MRI of the brain would be a more useful tool to determine if a stroke has occurred. A CT scan is less costly, and should always be done to evaluate stroke (for bleeding) but it may not see small changes, sometimes even 3 days later. ...Read more

After someone has had a stroke or TIA can you tell from an MRI or CT scan? Also how long after one of these do post symptoms occur?

After someone has had a stroke or TIA can you tell from an MRI or CT scan? Also how long after one of these do post symptoms occur?

Yes and no: A definite stroke or cerebral infarction is visible on brain MRI right away as changes on the dwi sequence will be seen. A TIA can occur and by definition no true brain infarction occurs so in those studies will be normal. The diagnosis of TIA is based on history of a sudden neurologic event that completely resolves within 24 hours. Reversible ischemic neurologic deficit is another term. ...Read more

Is it possible to miss a stroke on CT scan? Is MRI always done?

Is it possible to miss a stroke on CT scan? Is MRI always done?

Not always: Ct is not good for stroke in the first 6-24 hrs, especially in small strokes. It is always done however because it is more accessible, is cheaper, and because it is necessary to exclude a brain bleed. Mri is far superior in stroke detection, assuming the patient has no contraindications, like a pacemaker. ...Read more

Which first thing to do to mild stroke patient taking lipid profile or CT scan?

Which first thing to do to mild stroke patient taking lipid profile or CT scan?

Stroke: Both are important. A ct scan will allow the physician to determine the type of stroke and the extent of the injury. A lipid profile will help in assessing the need of aggressive cholesterol level treatment. The most common risk factor in stroke is hypertension. Check with your doctor for adequate diagnosis and treatment. ...Read more

Are strokes always detectable on a CT scan?

Are strokes always detectable on a CT scan?

No: A stroke may take 24-72 hours to be detected on a head ct. Mri is more sensitive in detecting strokes earlier, so if the clinical symptoms are quite strong and the ct head is negative, an MRI may be ordered afterwards. ...Read more

Hard hit to head 3 weeks ago. Ct scan 2 hours after hit was clear of bleeding. Having bad head and back of the neck pain now. Worried about stroke.

Hard hit to head 3 weeks ago. Ct scan 2 hours after hit was clear of bleeding. Having bad head and back of the neck pain now. Worried about stroke.

Take reassurance: A stroke isn't likely to be causing head and neck pain; they tend to manifest with motor/sensory problems or speech issues. If you suffered that significant/traumatic a blow to the head this could be post-concussive symptoms. You really should see your primary care doctor as they should be able to help minimize some of the symptoms and make sure nothing more worrisome is going on. ...Read more

Approximately how long after a stroke does it take for brain tissue to fully decompose and does it appear with the same density as CSF on a CT scan?

Approximately how long after a stroke does it take for brain tissue to fully decompose and does it appear with the same density as CSF on a CT scan?

It depends: The size and type of the stroke, ischemic vs hemorrhagic, are the most important predictors. For most ischemic strokes, the majority of liquifaction necrosis (the decomposition) takes place in a few weeks but continued healing will continue after the necrosis. For hemorrhagic strokes, it typically takes longer for the body to absorb the blood and complete the healing process. ...Read more

Any headache must be viewed as a valid medical disorder and the headache assessment must be comprehensive. Imaging like CT or MRI are very important to rule out secondary pathology. ...Read more

I have severe headaches & I have blurred vision & a lazy eye on the same eye. Could it be signs of a stroke? Had a CT scan but results came back normal

OCT of Optic nerves: If one of the pupils is dilated then it may be an emergency aneurysm. See an ophthalmologist or a neurologist urgently. If not, you need to have an oct exam of the optic nerves to see if the blurriness in the lazy eye is loss of nerve fiber layer. Oct can also show if you have a condition known as benign intracranial pressure. Then your eye doctor will refer to a neurologist for a spinal tap. ...Read more

Will an MRI show if someone is having a mini stroke?

Timing is important: The most sensitive test to determine if someone is having a mini stroke is the neurological examination. A ct scan or MRI scan will confirm or refute the clinical suspicion of a mini stroke. Changes on MRI scan after a stroke can be seen fairly quickly. However, the clinical examination is key. ...Read more

I have headaches everyday and I have history of strokes and antireism. I have had a cat scan and they say everything is normal. How can I stop them?

BE SAFE: I like many otc remedies to handle frequent headaches, and your pattern is c/w chronic daily headaches. Prevention is key to break up these patterns, and would suggest you consider butterbur, feverfew, magnesium, coq-10, riboflavin, etc. Some prescription items to consider include divalproex, topirimate, propranalol. Discuss with your doctor, as all of this needs control. Perhaps see neurology. ...Read more

Symptoms: Symptoms of numbness of the entire body from the neck down can have many causes. Of these many causes, a process involving part of the spinal cord in the neck would be the most concerning. Spinal cord problems could include syringomyelia or transverse myelitis, which can sometimes cause sensory problems without weakness.

Numbness from the neck down can also be caused by psychogenic (also known as somatoform, or "stress induced") problems, which can often be most challenging for the physician and patient to resolve. Psychogenic numbness can increase the chance of diagnosing something that is not actually there (leading to unnecessary and potentially dangerous tests and treatments) or lead to missing a diagnosis of an organic problem (potentially delaying appropriate treatment).

A stroke in the brain would probably not cause symptoms of isolated numbness of the entire body from the neck down.

Problems involving the spinal cord in the neck can be seen using an MRI of the cervical spine, usually done with and without gadolinium contrast. ...Read more

Do you think I should seek medical attention after mini stroke?

Do you think I should seek medical attention after mini stroke?

Yes--risks are high: Although a mini-stroke (tia or transient ischemic attack) does not leave the person with any deficit, he/she is at risk of future strokes, and there is some evidence to suggest that the risk is highest immediately after a tia. Patients need to get evaluated after a TIA to check risk factors and get possible treatment. ...Read more

Transient Ischemic Attack (Definition)

Tia (transitory ischemic attack) happens when blood supply to a certain area of the brain gets cut off temporarily. This causes a neurologic deficit - weakness, numbness, visual deficit or difficulty with speech. While TIA usually resolves, it indicates that there is a problem with your heart or blood vessels that can cause ...Read more
