Can a Pet scan diagnose Generalized seizures?

Can a Pet scan diagnose Generalized seizures?

Not really: Primary generalized seizures would not be expected to change anything on a PET scan. Partial-onset could show an area of altered metabolism. Either way, PET scans are not really a primary way to diagnose epilepsy. ...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

What would a neurologist refer patients for positron emission tomography scans for?

Endocrine issues + fatigue. Clear CT scan in Apr15. Symptoms persisted CT scan in Feb 16 clear. Could CT be missing SCLC. Is repeat scan necessary?

By SCLC, I presume: you mean small cell lung cancer...a type of lung cancer that is aggressive and is a neuroendocrine tumor which can produce ectopic hormones. But it certainly wouldn't be the first thing you would think of if you have "endocrine issues." The thyroid, pituitary, adrenal glands need full evaluation as well as other work-up. If lung CT "clear" would not pursue SCLC as cause. Best wishes:) ...Read more

Can MRI scan be used instead of CT scan to assess the bronciectasis b4 a possible surgery, ?Or as substitute to CT scan 2 see progress?
 Had CT scan b4

CT only: It is obvious that you wish to avoid ionizing radiation. However MRI is difficiult in imaging lungs of low density tissue, air-tissue interfaces causing artifacts, and respiratory, cardiac, and vascular motions.These are technicalities without any control. Ct is by far the choice for imaging bronchiectasis. ...Read more

CT Brain shows mass prepontine cistern CPA meningioma. Symptoms consistent with diagnosis. MRI contrast show no lesion. Symptoms persist! Now what?

Very strange: Not certain what to make of the disparity between the CT scan and the MRI. In some cases, a lesion is so small that it is missed by the artifact created by the thickness of the MRI slices. I would ask your doctor if an MRI of the brainstem with "thin slices" might be reasonable to confirm/refute the CT--with and without contrast. Take care and stay healthy! ...Read more

Been seeing a neurologist who suspects Viral meningitis (said spinal tap unnecessary)  CT scan normal.  Symptoms persisting after 2 weeks.  What next?

Response: Based upon information provided, must assume if your neurologist was correct, that you should be gradually improving by this point. However, full recovery could take several more weeks. If you have fever, stiff neck, HA, nausea/vomiting, would have f/u visit to re-evaluate. ...Read more

Is Full body PET scan or CT scan better for diagnosing Lymphoma? Which uses less radiation?

Both: The actual diagnosis of lymphoma requires tissue, usually excisional biopsy of an entire lymph node. Staging to see where other sites of disease could be is done with a combined PET/CT. The staging used to matter more many years ago when they would often give XRT or do surgery, it doesn't matter as much as it used to because almost everybody gets systemic chemotherapy for both Hodkins and non H ...Read more

No medical hist. developed respiratory prob.viral infect. with headache&vomiting, left facio-brachial seizures that became continuous, evolving into refractory status epilepticus, with bilateralization. Tests are fine. Now in coma and no diagnostic?

Seizures: This sounds like meningitis and encephalitis from an infection. Sometimes there are clues in the complete blood count. Bacterial infections typically show a predominance of neutrophils (also called granulocytes), while viral infections often show a predominance of monocytes or other lymphocytes. Also, if intubated then probably there are sedative medications changing mental status as well. ...Read more

If this is the first time I am having seizures but it lasted more than 30 minutes, is it considered status epilepticus?

Depends: The details provided are sketchy and definitions vary, but traditionally status epilepticus is defined as one continuous, unremitting seizure lasting longer than 5 minutes, or recurrent seizures without regaining consciousness between seizures for greater than 5 minutes. 5 min has been chosen as this is the time frame when the seizures are unlikely to self-terminate and neuron damage can occur. ...Read more

Episodic events: You seem to describe episodes when you lose control. This is referred to as episodic discontrol. There are several causes. Seizure activity can be an association, but the behavioral issues are the problem. Some lose control following a seizure, some with migraine, and some with emotional distress. Attempts to associate violent acts with seizures rarely succeed. Eeg during event is the test. ...Read more

Does a CT scan show if someone had a seizure? What are seizure symptoms?

Does a CT scan show if someone had a seizure? What are seizure symptoms?

Not usually: A seizure is uncontrolled electrical activity in a portion of the brain, which sometimes extends to involve the whole brain. Symptoms can be as little as a "1000 mile stare", to extreme flailing of the arms and legs. If the seizure is due to a mass in the brain, ct may see it, but MRI is better. Usually, the cause of seizures is a tiny "scar" in the brain, hard to identify even on ct or pet/ct. ...Read more

My son had a seizure a couple weeks ago and now we have noticed two lumps on his head. The CT scan was normal and didn't show any abnormalities.

Further Eval needed: If this was his first seizure ever, then he needs additional evaluation with a pediatric neurologist. Workup may include an MRI of the brain, EEG or other testing. More than likely, the lumps on his head are the result of the seizure and are related to mild head trauma. I would recommend that he see a pediatric neurologist. ...Read more

I've had six seizures since December Dr ordered ct of brain. All that show any seizure activity?

No no no: The CT scan was looking for abnormalities which could explain seizure activity. Things like bleeding, tumors etc. That is step one. Your doctor will almost certainly order neurological consult and EEG studies. If these are truly seizures the standard of care is obvious. Since you've had six seizures, my guess is they were atypical and did not result in an immediate referral to neurology ...Read more

Can a CT scan spot seizure activity then alert them to do an eeg?

Had a seizure had CT now they want me to have an MRI and EEG what could be wrong help can some one please answer

Time will tell: This is standard work up for seizure. Mri will look for an anatomic abnormality. The eeg will look for a functional abnormality ("misfiring brain cells"). Since they feel an MRI is necessary, tumor or bleed is unlikely. There's no way to tell what is wrong until all the testing is done. ...Read more

Post concussive: Post concussive syndrome can be accompanied by nightmares. Also, post traumatic stress disorder can cause nightmares. Other symptoms include avoidance of the perceived threat and flashbacks. Nightmares can also occur normally or as a part of other psychiatric and sleep conditions. Occasionally, medications can cause or worsen nightmares. ...Read more

July 5th CT scan for headaches.It was normal. 5 days later jerks when trying to sleep.Now think I'm having brief seizures at night.No history of seizu?

Hypnagogic jerks: Our bodies sometimes jerk briefly as we are entering sleep. It may wake us. They last less than one second. They are common and not harmful. The best way to know if you are having seizures at night is to have a sleep study, but what you describe does not sound like a seizure. ...Read more

Dr. K. Olson Dr. Olson
3 doctors agreed:

Probably: One seizure in 30 years with no central nervous system lesion to account for it (ct normal) and no progression (no further seizures - free of them for 14 years), leaves little reason for concern or to justify the eeg. This is if you are on no anticonvulsants. And assuming you do not have ongoing neurologic symptoms like difficult to treat headaches, perceptual changes, muscle weakness, lapses, etc. ...Read more

I fell on a concrete floor while having a seizure 6 days ago. I hit my head hard. They said they found nothing in the CT. Why does my head hurt still?

Multiple reasons: Your head could still hurt from a deep bruise in the scalp and even a bone bruise on the skull itself, a superficial hematoma, or sore spasming muscles in the scalp or even neck. If you continue to have pain that does not improve or notice any new symptoms, check back with your physician and express your concerns. Best of luck. ...Read more
