Does an MRI expose me to any unnecessary radiation?

Does an MRI expose me to any unnecessary radiation?

No: Mri (magnetic resonance imaging) uses magnetic fields rather than radiation. That is one of the benefits of using MRI instead of ct ("cat scans") or x rays. As far as we know, exposure to this level of magnetic energy is not harmful. If you have a pacemaker, cochlear implant, implanted nerve stimulator, or other metal in your body, you may not be able to have an mri. ...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

How much radiation is there with a mri?

How much radiation is there with a mri?

Well: Ultrasound uses sonic enery and actually MRI uses radiowaves which are electromagnetic radiation. But in the colloquial use of radiation you mean xrays or ionizing radiation. And both u/s and MRI does not use ionizing radiation. ...Read more

Are there any side effects of MRI radiation?

Are there any side effects of MRI radiation?

MRI doesn't: Use ionizing radiation (used with ct scans and plain x-rays studies). It uses magnetic fields to make images and these have not been shown to harm the human body. That said, patients with certain kinds of pacemakers and other implanted devices can't be imaged with MRI because of the potential to disrupt the device or otherwise harm the patient. ...Read more

Why MRI test does not count danger if it use same type of radiation as cell phone?

Why MRI test does not count danger if it use same type of radiation as cell phone?

Think about it.....: Think about the time exposure issue - if nothing else. Actually the probability that it's the exact same type is low, but... Most will have no more than a very few MRIs in their lifetime and most spend from an hour to several hours a day on their cell. That's often 365 days per year. It's not hard to see a difference. ...Read more

Results of my last MRI were inconclusive and suggested another with contrast. PCP suggests that its too much radiation for my body. How so? 1 more ok?

MRI has no radiation: MRI does not use ionizing radiation (high-energy radiation that can potentially cause damage to DNA, like the x-rays used CT scans). ...Read more

What is the difference between an MRI and a cat scan? Except for the radiation factor.

Physics: The physical phenomena on which these imaging techniques are built are very different, each is best suited for different purposes. Cat scans are sophisticated x ray, they rely on the degree of absorption of gamma rays (bones, ca, other metals will contrast most). Mri is better for softer tissue imaging because it depends more on the behavior of hydrogen atoms and h2o in the strong magnetic field. ...Read more

Does MRI Radiation can be danger as Cell phone radiation since both work on electromagnetic?

Does MRI Radiation can be danger as Cell phone radiation since both work on electromagnetic?

Frequency is a key: issue because energy per photon correlates with the frequency of EMR. Study: https://en.wikipedia.org/wiki/Electromagnetic_radiation. Additionally, issue is not just EMR energy transmitted but absorbed (versus just passing through without apparent effect) combined with biologic responses, thus no one 100% understands. MRI (actually NMRI) uses intense magnetic fields & RF EMR, not ionizing like CT. ...Read more

Can scarring or cirrosis of liver be diagnosed by ultrasound and mri?I m scared of CT because of radiation.

Can scarring or cirrosis of liver be diagnosed by ultrasound and mri?I m scared of CT because of radiation.

Cirrhosis: This condition can only be suggested by imaging studies, including ct. The only definitive way is by liver biopsy. If, however, there is cirrhosis the secondary effects of that will suggest its presence. You do not need imaging for that except out of curiosity. If you have history of liver damaging conditions and secondary changes, the odds are overwhelming and not sure ct will help anything. ...Read more

Gamma Rays (Definition)

This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...Read more
