Mri Scan For Ear Problems
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
Shadow on CT scan mastoid bone area, MRI results clear, had ear infection and still do. Would MRI only show intercrainial and not bone disease?
Probably: Mri and ct are complementary studies so there is always the possibility that one study will show an abnormality that the other doesn't. Typically a 'shadow' in the mastoid bone means fluid and that should show up on mri. But not knowing for sure what is meant by 'shadow' in your case, i can't be 100% about that. Ask your doctor about your case specifically or an ENT specialist or a neurologist. ...Read moreSee 1 more doctor answer
If I'm having vertigo and blood tests good, CT scan of brain clear, sinus scan not, and hearing tests good. Could this still mean inner ear disorder?
Quite a Lot: MRI is more helpful for soft tissue problems of blood vessels, inflammation, demyelination of brain tissue, and fluid collections. It seems you are undergoing a lot of tests, but without a clear diagnosis you can not be certain of the correct treatment. Ask your physician to explain the different treatments these tests will suggest. Tests are not useful, solely, because you have symptoms. ...Read moreSee 1 more doctor answer
Not very well: Ct techniques used to image the temporal bones or sinuses are tailored specifically to evaluate these areas. Only small portions of the brain are even included in the field of view. Also, the images are processed to give the best bony detail which makes the soft tissues difficult to evaluate. While an abnormality may be detected, these scans are not sufficient to evaluate the brain. ...Read moreSee 1 more doctor answer
A recent CT head scan (no contrast) showed calcified carotid siphons, should I have further tests done?
Yes: If you have intracranial calcifIc arterial disease, you may also have extracranial calcific arterial disease. A carotid ultrasound would be a good idea. Also a cardiovascular calcium scan. If your brain arteries are looking bad, your heart arteries could also. ...Read moreSee 1 more doctor answer
8years ago I did ct scan for head
5years Xray for kidney
2months panoramic Xray for teeth
2week Xray of spine
2days mri of spine
Can this cause cancer?
No: All x-ray exposure is cumulative, but doses are minimized as much as possible. your Panoramic x-ray, for example, is less radiation than you would receive spending a day in the mountains, or two on the beach. If you are concerned, schedule an appointment with your General Physician for evaluation. ...Read more
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
Does a CT scan rule out brain aneurysm? 6 months pain behind right ear and upper neck with dizziness/blurred vision. CT normal. What to do next?
MRI vs CT: A ct myelogram (where contrast is injected to highlight discs, nerves, etc) is comparable to a back mri. Orthopedic surgeons & neurologists have their preference. Both will do a thorough exam before recommending an imaging study. Conservative treatment with analgesics, muscle relaxers, physical therapy may be enough at first. ...Read moreSee 1 more doctor answer
Whats better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.
CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and cea can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...Read more

Getting CT scan for sinuses done in two weeks. Have constant congestion, loss of smell/taste. Issues swallowing. Could scan show issues swallowing?
No: A CT of the sinuses is a very focused study, and while it does show the back of the throat, tonsils, adenoids, this is all stuff the doctor can see just by looking in your mouth so the CT adds nothing to the evaluation for swallowing. It will get some fantastic pictures of your sinuses though and is primarily used to determine if surgery or balloon sinuplasty may be helpful. ...Read more
