Block Of Sinuses And Space Which Might Indicate A Stroke Or Small Blood Clotresults Of Mri Head Scan
Sinuses are air filled spaces in the head that have several proposed functions: 1. They serve as shock absorbers in cases of head trauma 2. Lighten the skull 3. Humidify and filter the air while also producing mucus 4. Play a role in vocal resonance. The head contains 4 paired sinus cavities: maxillaries (cheek) under the eyes, ethmoids(between the eyes), frontals (above ...Read more
If a brain tumor is causing forehead pressure tightness and dizziness, would it show on CT scan without contrast? Like brain shift or some evidence?
Well...: Tumors larger than 6 mm will show on a CT scan with contrast. But at that size it would be highly unlikely to have any of these symptoms. An MRI is way better to visualize brain pathology. Yet at this point I doubt you have a large enough brain tumor that would cause these symptoms... Do not panic, sounds more like a sinus problem ...Read more
Doubtful: A standard CT scan of the brain would have challenges in determining inner ear issues or blood flow per se. Additional modifications would be needed for the latter (along with the appropriate clinical symptoms), and other types of scans would be better for evaluation for the former (e.g. MRI, again, with the appropriate symptoms). ...Read more
What does 'diffuse severe attenuation of the left vertebral artery" mean on a neck ct scan with contrast? Could it be cause of previous spontaneous arterial brachial clot or subclavian clot?
Many times: These studies have limited resolution and can miss abnormalities. Mra is better than MRI as it shows the blood vessels better and is useful for screening. Even mra is limited resolution and can miss lesions smaller than 2-3mm. For high suspicion a catheter angiogram is the best study. ...Read moreSee 2 more doctor answers
Can mri's show if there is less blood flow to the brain from a pinched or compressed vertebral artery? If they just do a scan of your brain notneck
What does increased attenuation in the frontal lobes likely to secondary beam-hardening artifact mean on a CT of the head?
Problem with machine: This description is given when there is a part of the scan that is blurry. There is an increased signal which looks specific for a pattern that shows up when the machine malfunctions and causes the artifact. It should be nothing you have to worry about. ...Read moreSee 1 more doctor answer
Brain MRI reveals complete opacification of the bilateral frontal and ethmoid sinus, otherwise normal, could this be cause of daily head pressure
Probably not: Ultrasound is the best test for blood clots in the legs. A CT of the leg without contrast would only show indirect signs - edema, or swelling, in the tissues may show up if the DVT is extensive enough. With IV contrast, a DVT may be visible on CT. In general, a "normal" CT of the leg is not sufficient to rule out a blood clot. ...Read more
Can a CT scan with out contrast show if someone has a significant amount of blood in the brain from a ruptured anurysm?
Could a narrowing of a blood vessel in the brain block and cause tia, if epinephrine levels rocket from fast music?
Does a sinus CT show the eustachain tubes? Or does a CT of the temporal bones do a better job of this?
Following an ischemic stroke would the dead area eventually appear with the same density as CSF on a CT scan?
I had a brain MRI to look for ischaemia and inflammation. Could the the 3mm hyperintensity be related to either of these?
Sometimes: Usually not in a young person. However, the older one gets, more calcium buildup along the arteries can sometimes be seen in x-rays which can hint that the arteries may be "widening". This would need to be confirmed with an ultrasound, ct scan, or MRI depending on the situation. ...Read more
Can MRI/X-RAY of the arm miss a small sarcoma? Both show normal, no mass,fluid build up,aneurysm, or vascular malformation in area & vessels. Now what
What does dr mean by : Evidence of moderate diffuse disease of the mid and distal LAD, which appears to be a NARROW vessel? In a Heart Cath report. Thank you.
36 yo?: It means your main coronary artery is filled with cholesterol to the point that the artery is narrowing. This is a main artery of the heart that feeds the heart if it is blocked off you have a heart attack. Now you need to know the percentage of blockage for this will determine if you need a stent or not? I any event you need to live a healthy lifestyle eat well and once cleared by cardiology get ...Read moreSee 1 more doctor answer
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
