Can an EEG (electroencephalogram) detect brain tumors?

No: Eeg can show presence of seizure brain wave activity.These seizure brain activity can be caused by different conditions such as metabolic abnormality, lack of blood supply to brain cells, medication, epilepsy, brain tumor related, etc. It analyzes the brain "function" not the anatomy thus it can't detect brain tumor specifically. Mri needs to be done to detect brain tumors. Discuss with your md. ...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

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

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

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 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

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

Can an MRI scan show cognitive impairment?

Can an MRI scan show cognitive impairment?

NO: Mri is an imaging device that is independent of function. Think of your car mechanic and a problem with your car. Lifting the hood and looking is like getting an mri. A good mechanic will want to turn it on and drive around and think carefully about what may be wrong. A good brain mechanic will ask appropriate questions and get appropriate tests and think about what may be wrong. ...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

Do regular CT scans show unruptured aneurysms?

CT scan: It depends what do you call a regular ct scan but usually IV contrast dye is needed to visualize the aneurysm. There are non contrast exams and others where IV contrast is employed. Where is the aneurysm located ?. If it's large and calcified and perhaps located in the abdomen or chest it can be suggested by the non contrast ct. An ultrasound can detect readily in the abdominal aorta. ...Read more

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

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
