I suffered of anxiety during a brain MRI evaluation , and it can not be completed. What others procedures (b.Map, CT scan) are useful for the brain?

I suffered of anxiety during a brain MRI evaluation , and it can not be completed. What others procedures (b.Map, CT scan) are useful for the brain?

Options: It is not uncommon for patients undergoing MRI scans to feel claustrophobic and have to end the test prematurely. If the information needed is important to make a diagnosis or determine treatment, you can try having the procedure with an open mri. Alternatively, if your doctor needs the clarity of the regular MRI images, you may benefit from mild anti-anxiety medications taken before the scan. ...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

How do u get a full evaluation of the brain, heart, blood? I'm getting very lightheaded & has had mri&ct 6mths ago normal. & had a full blood work up!

How do u get a full evaluation of the brain, heart, blood? I'm getting very lightheaded & has had mri&ct 6mths ago normal. & had a full blood work up!

Hmmm...: Well, i doubt we'll be able to do this in 400 characters, but the lightheadedness is often broken down into several categories. If it's fainting or near-fainting spells, that's called syncope or near-syncope and we usually check with a cardiologist about that. If it's like the sensation you get when you stand up too fast, it may be low blood pressure, especially if you're on meds. ...Read more

Pet/ct fdg 18 test on the brain, what does this mean?

Pet/ct fdg 18 test on the brain, what does this mean?

Imaging metabolism: PET/CT of brain involves injection of isotope FDG18 intravenously and after waiting about forty five minutes imaging the brain with camera acquiring information about metabolism of brain. The isotope accumulates according to metabolic activity of brain. Can be used to detect tumors, in epilepsy for seizures, and some metabolic disorders. In general malignant processes are most active. ...Read more

What does the pet/ct scan of the brain tell you?

What does the pet/ct scan of the brain tell you?

Looking for what?: It depends on what is being looked for. Pet/ct looks at the metabolism. Or the function of the area scanned (brain in this case), using different radioactive drugs, or tracers. The most common is f-18 fdg, an analog of glucose, which images glucose consumption. Other radiotracers look at protein synthesis or for evidence of the plaques that are associated with alzheimer's. ...Read more

My pet-ct scan for hotpshkins lymphoma came up with increased metabolic activity around brown fat in base of neck, should I be concerned?

My pet-ct scan for hotpshkins lymphoma came up with increased metabolic activity around brown fat in base of neck, should I be concerned?

No: Brown fat is metabolically active in order generates heat, and for this reason more likely to be active during the winter months. Since brown fat uses more glucose than normal fat, it lights up on a FDG pet. Correlation of pet images with the ct portion of the exam can easily identify the active regions as fat rather than lymph nodes or tumor. Typical location is around the clavicles. ...Read more

I am thinking, can fdg-18 that is used for a pet/ct of your brain, cause muscle burning? I can trace it back to that point where it started. Any possibility?

I am thinking, can fdg-18 that is used for a pet/ct of your brain, cause muscle burning? I can trace it back to that point where it started. Any possibility?

No: After the FDG decays. The fluorine atom turns into a heavy oxygen atom o-18. This allows the FDG to become a normal glucose which is rapidly metabolized by the cell. The half life for the radioactive fluorine is only 110 minutes so after a day virtually all of the FDG would have been eliminated. ...Read more

Pet/ct scan of brain shown bilateral temporal(more severe on left side)parietal, thalami & basal ganglia hypo metabolism.What does it mean, pl advice.

Pet/ct scan of brain  shown bilateral temporal(more severe on left side)parietal, thalami & basal ganglia hypo metabolism.What does it mean, pl advice.

MaybeNothing: Pet/ct can show a region of hypometabolism, yes. But you describe many areas, including bilateral areas. That is much harder to accurately define on these kinds of tests, and results should be viewed with caution. Also, remember that the metabolism images should fit with what is wrong with the patient. ...Read more
