Can a CT scan pick up an acoustic neuroma?

Can a CT scan pick up an acoustic neuroma?

Not usually: Ct scans use x-rays and are better for imaging bones than soft tissue. A large acoustic neuroma may be seen on ct scan, but MRI with a contrast medium is able to detect small acoustic neuromas that may only be several millimeters in size. Mri uses a magnet for imaging which also has the benefit of no x-ray exposure. ...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

Will at CT scan or MRI pick up a parasite?

Will at CT scan or MRI pick up a parasite?

In many instances: Usually we see the results of the body's reaction to the parasite, rather than the parasite itself. Parasites such as cysticercosis can deposit material which en sites the body to react - for instance in the brain. In other situations a byproduct of infection such as an amoebic abscess in the liver can be identified. Virtually every organ system can show the result of parasitic infection. ...Read more

Can a CT scan always detect a tumor?

Can a CT scan always detect a tumor?

Only at certain time: Bulky lesions in the retroperitoneum or masses growing off the bowel are frequently visualized. The same holds true for metastatic lesions to liver and lung. When we work up a patient for extensive surgical resection and want to be sure no metastatic focus is present to be addressed or might obviate the surgical procedure, a PET/CAT scan is employed where any malignant lesion lights up. ...Read more

What would an MRI of my head show that a Sinus CT Scan and a Maxiofacial CT Scan didnt?

What would an MRI of my head show that a Sinus CT Scan and a Maxiofacial CT Scan didnt?

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 more

Possible for a 6.6mm tumor to not show up on X-ray or CT scan?

Ct scan can reveal a brain tumour and an MRI showed nothing. Which to believe?

Strange: Usually an MRI is more sensitive (better) at detecting rumors than CT. Did the radiologist who read the MRI have access to the CT and its report? It is possible that something that was thought to be a mass on a CT turned out not to be one on MRI. ...Read more

Would a CT scan pick up on parasites in brain?

Would a CT scan pick up on parasites in brain?

Parasites: Ct scans detect changes in the brain substance that are produced by a variety of diseases. Sometimes the findings may suggest one illness over another, but they are never specifically diagnostic. Thing like cysticerus, toxoplasmosis, and others are very likely but must be proven by other techniques. ...Read more

Will a brain aneurysm show up on a plain CT scan of the head?

Will a brain aneurysm show up on a plain CT scan of the head?

USUALLY NOT: Since aneurysms are a 'defect' in the arterial system --they can really only be seen with a contrast ct study (angiogram) or a mra (mri-angiogram). One time i did have a patient with a leaking brain aneurysm which the effects of which were barely visible on ct but confirmed on mra--and she made it! ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
