How much for a CT scan vs mri?

How much for a CT scan vs mri?

About the same: There were appreciable differences in previous years but most facilities charge about $800-1000 for a ct and about $1200-1500 for an mri. It can vary greatly depending on where you have it done. Call ahead and try to negotiate a price. ...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

Would a plain CT scan show an unruptured aneurysm in the brain ?

Would a plain CT scan show an unruptured aneurysm in the brain ?

Need contrast: Very difficult to see aneurysms in the brain without contrast. If you are concerned about this as a possibility you should ask your doctor about your risk. ...Read more

Is it possible for MRI or CT scan to detect brain cancer?

Is it possible for MRI or CT scan to detect brain cancer?

Yes: A CT scan can detect a brain tumor, but will be better able to detect a tumor if it performed with IV contrast. Mri with contrast can detect very small tumors that may not be seen with a ct scan. ...Read more

Can MRI scan be used instead of CT scan to assess the bronciectasis b4 a possible surgery, ?Or as substitute to CT scan 2 see progress? Had CT scan b4

Can MRI scan be used instead of CT scan to assess the bronciectasis b4 a possible surgery, ?Or as substitute to CT scan 2 see progress?
 Had CT scan b4

CT only: It is obvious that you wish to avoid ionizing radiation. However MRI is difficiult in imaging lungs of low density tissue, air-tissue interfaces causing artifacts, and respiratory, cardiac, and vascular motions.These are technicalities without any control. Ct is by far the choice for imaging bronchiectasis. ...Read more

What is the difference between pet scans, mri, ct, and bone/gallium scans?

What is the difference between pet scans, mri, ct, and bone/gallium scans?

A lot: Sorry to be so vague. They are very different in what can be seen and what can be diagnosed. Not enough room to go through the details. The Internet has many resources for this information. Try this one: http://www.radiologyinfo.org/ ...Read more

How are mr scan and a CT scan different?

How are mr scan and a CT scan different?

Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density. Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor. ...Read more

Would dementia show up on MRI or cat scan?

Would dementia show up on MRI or cat scan?

Not necessarily: Mri and cat scans show anatomical brain changes only, not functional ones. If a dementia is far enough advanced to change brain structures, it would "show up" on these scans. However, there may be a long decline in brain function before that point is reached. There are functional scans which might detect changes before anatomic anomalies can be seen. A normal MRI does not "rule out" dementia. ...Read more

How do a pet scan and a MRI scan differ?

How do a pet scan and a MRI scan differ?

See below: An MRI or magnetic resonance imaging is a study that provides anatomical description of a part of your body. A pet scan can provide further information aside from how it looks or appears. It utilizes radioactive material or tracers that see how cells in your body function. It can detect cancer cells not evident on MRI or ct, heart disease, infection and even neurological conditions like dementia. ...Read more

What can a hip/pelvic CT scan show that a MRI cannot? (dr ordered bilateral hip/pelvic CT scan 2x45min in machine-worried about radiation)

What can a hip/pelvic CT scan show that a MRI cannot? (dr ordered bilateral hip/pelvic CT scan 2x45min in machine-worried about radiation)

The CT: Gives fine detail about the bones of the pelvis and hips. If your doctor is worried about arthritis or femoral-acetabular impingement this may give more information. Best to ask your doctor and relay your concerns. ...Read more

In what aspects CT scan is better than MRI scan?

Looking at bone: The CT scan is better than MRI in detecting bone fractures or pathologies involving the bone. MRI is better at distinguishing between soft tissues. CT scan is also faster & quieter than MRI. However, the CT scan uses radiation & there has been an explosion of radiation-related conditions in recent years. Each modality measures different things. So ask your doctor if the test is needed or not. GL. ...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

Is MRI or CT better for detecting sinus infections?

Is MRI or CT better for detecting sinus infections?

CT is better: Although both MRI and CT can demonstrate sinus infection, CT is superior in demonstrating the thin bony walls of the sinuses, which are very important for evaluation of disease severity, as well as guidance for treatment options. ...Read more

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 more

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.

Why worried?: Why are you worried? Do you have symptoms or abnormal labs? If the ct was normal and used a specific pancreas protocol, then an MRI of the pan creas may be the best next test. Since it does not use radiation, there is little risk for you. ...Read more

How are an MRI and CT scan different?

How are an MRI and CT scan different?

Differences: The ct scan uses radiation from multiple x-ray devices to see internal organs. The MRI uses very strong magnetism to orient the body's water molecules and see internal structures such as ligaments, joints, brain, etc. Each study has its own individual benefits or indications. ...Read more
