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

Mri (Definition)

Magnetic resonance imaging named for the effects of the strong magnetic field upon the atomic and molecular phase or spin and the image created when that magnetic field is altered and the excited particle changes gibing off a signal that is recorded and interpreted by a complex computer algorithm, ...Read more

Would MRI scan show kidney disease?

Would MRI scan show 
kidney disease?

"Disease": "Disease, " yes; but not necessarily what type of disease. "Dense"/scarred parenchyma may still need to be biopsied to determine the actual tissue disease. On the other hand, an MRI may be a better test to assess rensl masses (eg renal cell carcinoma vs benign neoplasms). ...Read more

Can CT scan without contrast show brain aneurysm?

Can CT scan without contrast show brain aneurysm?

Unlikely: Ct scan without contrast is unlikely to show an aneurysm unless it is very large and is calcified. A ct angiogram is a better study to visualize an aneurysm. ...Read more

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more

Can CT scan diagnose meningitis?

Not diagnostic: A ct is part of the work up of meningitis. However, a lumbar puncture is the test that typically allows for a diagnosis of meningitis by obtaining cerebrospinal fluid for study and cultures. ...Read more

Could a CT scan show anything a MRI scan cannot ?

Yes: Some Doctors who interpret MRI exclusively in their practice will promote the idea that MRI is the best imaging technique for every condition. To a lesser extent, some Doctors will say CT. Some doctors swear by Ultrasound imaging. There are strength and weaknesses of each modality, with considerable overlap in information produced. And each modality has some advantage over others. ...Read more

Will MRI scans show cancer?

Will MRI scans show cancer?

Depends: Mri is very good at showing abnormal tissue from normal tissues and can pick up various cancers very well. Some cancers, however, can be small and not well seen on mri. Some may be better seen on ct. Cancers involve in the stomach and colon are usually not well seen and may require endoscopy or colonscopy. Some breast cancers are also better seen on mammograms than mri. ...Read more

Is orbital CT scan and CT scan sinus the same?

Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read more

Can MRI scan detect depression?

Can MRI scan detect depression?

Answer via Questions: We rely on the answers people give to questions about their thoughts, emotions and behaviors to determine whether (a) they have symptoms of depression; (b) how many they have; & (c) how severe each is/how much each interferes w/ person's ability 2 function day 2 day. Standard MRI machines produce great still shots of the brain but those pics don't show depression or what someone is thinking, etc. ...Read more

How do pet scans, mri, ct, and bone/gallium scans differ?

How do pet scans, mri, ct, and bone/gallium scans differ?

Different mechanisms: Mri uses magnetic radiation( no x-ray) for anatomic localization and characterization of different parts of body, water and fat constitution of different tissues.Ct uses x-ray to characterize anatomy of body, better for bone than mr.Pet, bone, gallium scans use radio tracers intravenously.Petglucose metabolism of tumors, gallium (infection/tumor), bone scan for fxs, tumors, infection bone metabolism. ...Read more

Does the CT scan show labyrinthitis?

Does the CT scan show labyrinthitis?

No: Labyrinthitis is not diagnosed with either ct or mri. It is a clinical diagnosis, meaning a diagnosis that is made by your symptoms and examination. There is a test called an eng which can be done as well that looks at how your eyes move in response to challenges to your balance system. The eyes are "hard wired" to the inner ear and in cases of vertigo they will move rapidly. This can be measured. ...Read more

Do CT scans see brain tumors?

Do CT scans see brain tumors?

They can: The diagnostic yield of increased with use of IV contrast material as some tumors disrupt the so called blood brain barrier affording the contrast the ability to infiltrate from the blood stream into the tumor. Small tumors that have not disrupted the integrity of blood vessels may escape detection on CT especially if the have the same radiographic tissue density as their surrounding tissue. ...Read more
