What Does An Mri Of The Brain Show That A Ct Scan Doesn T
If a brain MRI shows no acute process but only a nonspecific signal change in left parietal, is it advisable to do a CT scan considering its risk?
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
Would a Brain MRI W/O Contrast & a CT Scan with and W/O Contrast show a brain tumor causing symptoms? Worried that it could have been missed.
Would a Brain MRI without Contrast & a CT Scan with and without Contrast show a brain tumor causing symptoms? Worried that it could have been missed.
No symptomatic tumor: It is a pretty safe bet that MRI together with contrast CT can exclude a symptomatic tumor (mass) in the head. That does not mean all causes of headache or neurologic complaint are seen. Only your practitioner can give more advice to "put your mind at ease" and further direct your diagnostic journey. ...Read more
Also, very fast!: Agree with excellent answer above. Additionally, ct scans have the advantage of being much faster than MRI scans, and they are much more widely available- if you come into a small hospital's er at 3 in the morning, they will likely be able to do a ct immediately, while an MRI might wait until the next morning (if it is available at all!). ...Read moreSee 3 more doctor answers

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 moreSee 1 more doctor answer

Safe for someone who has shunt for normal pressure hydrocephalus to get brain MRI for suspected pituitary adenoma? If no, is cat scan used instead?
Check with neurosurg: Check with the neurosurgeon as to the type of shunt in place. With normal pressure hydrocephalus, it is very common that the shunt is a programmable shunt that allows the neurosurgeon to change the amount of drainage with a special magnet. There are some that are MRI resistant and some that aren't(these need reprogramming soon after mri). If it is non-programmable, you don't need to adjust it. ...Read moreSee 1 more doctor answer

I am super paranoid that im not gettin enough oxygen to my brain, does a MRI CT scan show that? dizzy/off balance for months, both came back normal
Just paranoid: Unless you are severely anemic, in severe heart failure or have severe occlusion of the blood vessels in the neck your brain is getting all the oxygen it needs. You can get more oxygen to your brain by exercising. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
