Which one is better at detecting blood clots (in the brain) MRI or CT scan?

MRI. Blood clots can lead to strokes, which MRI is more sensitive at detecting. To evaluate blood vessels for narrowing, one can use either MRI or ct.
Neither. If you are looking for a blood clot, an angiogram and an mra are the most specific. After the damage from a clot is done, the quickest test to show it will be an mri. Ct will show a stroke 48-72 hrs unless it's a bleeding stroke, w in which case it will show sooner.

What can a CT scan of the brain catch that a brain MRI scan cannot?

Bright stuff !! A ct of the brain is really good at visualizing highly calcified objects (think x-rays) such as bone. Blood can be visualized in areas where it should not be like the subarachnoid space. Ct's are great for visualizing acute bleeds such as might result from trauma. 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!).

Not much. Perhaps detecting a skull fracture or bony abnormality (like in the temporal bone). Mri is more sensitive than ct in detecting stroke, most hemorrhage and tumors. That being said, ct is often done first because it is fast and available 24/7. Read more...
Depends. The most common reason for an immediate CT scan in the Emergency Room is to evaluate for abnormal bleeding onto the brain. Time is critical for a patient with bleeding into the brain, and a CT scan may take less than one minute to perform, while an MRI may take up to 30 minutes. Bone imaging with CT is also better than MRI at times. MRI imaging is better than CT of the brain for many diseases. 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.

MRI. A MRI with contrast is sufficient to detect evidence of a brain tumor. If there is any question as to whether a brain tumor is present or not, one can opt to repeat the MRI of the brain with contrast three months after the last MRI brain was obtained. . Read more...
A brain MRI. With contrast would provide the highest sensitivity for detection of a brain tumor, but considering the negative noncontrast MRI and negative CT with/without contrast, there is a very low likelihood of a brain tumor, and a MRI with contrast would probably only be necessary if there is a high clinical suspicion.

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.

Does a radiologist look for regional brain atrophy in a routine brain mri/ct scan?

Yes. The radiologist looks for any abnormal anatomical variation whether it be atrophy, malformation, infarction, hemorrhage, tumor or mass effect. Thanks. Read more...
They should. Radiologists are trained to look for everything on the scan. Certainly if there is asymmetric atrophy he/she should be able to see it. Read more...

I got infraorbital neuralgia, Brain MRI=good, CT scan = chronic maxillary sinus issue on side of the neuralgia. Could there be a relation?

Yes. Yes. Strong chance of relationship. See ENT doc with special expertise in sinus problems for management of chronic sinusitis. Resolve chronic sinusitis and see what happens to infraorbital pain. "Burning" pain is difficult to treat. If no resolution, see orofacial-TMJ doc. Read more...

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?

Not necessary . It is not necessary to undergo a CT. Of course it would depend on why you had the MRI in the first place. Most of these findings that are called nonspecific are vascular spaces and not by themselves a cause to worry . Read more...

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?

This might help. The amount of time required for an MRI of the head varies, but generally it is brief (minutes rather than hours). To prepare, try this: (1) take an active (rather than passive) perspective; you're hiring the medical team to take pictures of your head; (2) learn "the relaxation response" (rr)(instructions online); (3) practice the rr daily while lying down with your head in a box. Relax and go on. Read more...
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...
