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

What would a CT head scan show versus having a MRI head scan? And with or without contrast?

What would a CT head scan show versus having a MRI head scan? And with or without contrast?

Need to talk with : Your ordering doctor. Depends on what is being evaluated, and the differential diagnosis. Ct is a good quick screen for bleed, masses, skull fractures, etc. And MRI gets you good soft tissue details, and lets you better evaluate the gray and white matter, also allows you to evaluate bleeds, helps you tell if old or new bleed, also helps you see tumors, strokes (ischemic areas, atrophy, etc.). ...Read more

Can MRI or CT scan show brain damage from stimulants?

Can MRI or CT scan show brain damage from stimulants?

Stimulants: Stimulants such as Cocaine and amphetamine exert their effects on the user's nervous system and change the user's emotions, behavior, and affects cognition. They may cause miicrovascular ischemic disease of the brain which is unlikely to be detected by MRI or ct scan. ...Read more

Could MRI or CT scan detect brain cancer?

Could MRI or CT scan detect brain cancer?

Sure: Mri would be the imaging test of choice, though often we start with a ct. Ultimately, you'll likely need a biopsy to prove it's a cancer. ...Read more

Can a non contrast head CT scan miss anything?

Can a non contrast head CT scan miss anything?

Yes: A ct scan with IV contrast will be more sensitive for detecting lesions than a non-contrast ct, and an MRI with contrast is even better than a ct scan. ...Read more

Would a head MRI show the neck or no?

Would a head MRI show the neck or no?

Head MR: A typical mr of the "head" shows only the head and not the neck region. To see the neck that would have to be ordered in request for the study. ...Read more

Can a CT scan of the head without contrast dye detect brain aneurysms?

Can a CT scan of the head without contrast dye detect brain aneurysms?

Yes: While plain ct scan is not the best test for aneurysm, large aneurysms can potentially be spotted. Mri is a better test, especially when blood vessels are looked at as well. ...Read more

Are there things that an MRI head scan can pick up that a CT head scan can't pick up?

Yes: CT is a valuable tool in detecting intracranial abnormalities, and is superior to MRI in depicting some things, but across the board MRI is more sensitive at picking up more abnormalities than CT. ...Read more

Does a head MRI with contrast show an accoustic neuroma?

Acoustic neuroma dx: MRI with gadolinium is the imaging test of choice (Gold Standard) for diagnosis of an acoustic neuroma, a tumor of the 8th cranial nerve. ...Read more

How dangerous is a head CT or MRI with contrast?

How dangerous is a head CT or MRI with contrast?

Both are very safe.: The ct uses a small amount of radiation and sometimes an injection into the veins is made to see the images differently. The MRI uses no radiation and it can also use an injection for better diagnosis, . ...Read more

Can previous strokes be seen on CT or MRI of brain?

Yes, MRI: can visualize almost all prior strokes. CT is somewhat less sensitive, and will be able to pick up most of the larger old strokes, but may not pick up very small old strokes. ...Read more

Can cervical spine MRI or full spinal MRI with contrast detect tracea or windpipe tumours?

Can cervical spine MRI or full spinal MRI with contrast detect tracea or windpipe tumours?

Maybe: Mri's are very focused exams. To get the best quality imaging of the area of interest, the field of view is limited as much as possible. The trachea may have been included, but not necessarily. You should speak with your doctor or the radiologist that read the study and ask them to look at the trachea. If it is seen, they can answer your question and if not they can recommend another test. ...Read more

Could a mri/ct scan detect all brain injurys?

Could a mri/ct scan detect all brain injurys?

Nope: Sometimes you can see evedence of bleeding. With traumatic brain injury sufficient to cause changes on ct typically survival is markedly reduced. Certain types of MRI done at the right time following a brain injury can sometimes show evidence of cerebral contusion. Much of the damage done with traumatic brain injury is microscopic (too small even with diffuse axonal injury) to be seen on mri. ...Read more

Can a negative ct scan without contrast of the head miss a brain tumor causing headaches?

Can a negative ct scan without contrast of the head miss a brain tumor causing headaches?

Yes, it can: Did you go to an ER with H/A & they did a knee-jerk don't-sue-us CT scan which was normal? If you've had H/As for at least 3 years, the chances of finding a tumor on brain imaging are no greater than for someone with no history of H/A. Are your headaches of recent onset, relentless & worsening? If not, you can find something else to worry about, like the outcome of the 2016 presidential election. ...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

Mri (Definition)

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
