None. By radiation, we're referring to ionizing radiation, or radiation with high enough energy to cause molecular damage, or possibly DNA damage. Radiation therapy, CT scan, Nuclear scans and X-rays all use ionizing radiation. MRI uses magnetic fields to induce electric currents, and employs radiofrequeny waves ( a type of electromagnetic radiation) that is not ionizing radiation. It is a form of energy, and thus metal objects, and even metal in tattoos can heat up and cause burns.
None. It uses magnetism and radiowaves. No x-rays.
An MRI scanner uses radio waves and a strong magnetic field. It doesn't use any ionising radiation e.g. X-rays.
No. MRI uses a very powerful magnet.
none, it is a magnet
There is no ionising radiation (e.g. X-rays) used in an MRI scan. It utilises radio-waves and a strong magnetic field but no radiation.
A CT scan is about $300 to $6750, while a MRI scan is $400 to $12,000.
it produces better images of soft tissues - apex
Just 200
MRI scans are one of the safest type of scan in modern medicine. The detailed results it gives without the danger of radiation is remarkable. There is one well known hazard however, that is that any metal in a persons body will damage the body due to the magnetic aspects of the MRI.
Any exposure to radiation isn't great for you. I recommend to only get one if you really need one.
no it is not possible to have an MRI scan because the dfibrillator is dirupted by magnets and that is what an MRI is, a giant magnet.
MRI uses radio waves; a CT scan uses x-rays.
A bone scan, or x-ray is simply a different type of scan than an MRI. No kind of scan is better than another, it simply depends what the scan is trying to ascertain.
A PET scan shows what level / stage (if any) the cancer is at. An MRI scan doesn't do this, the reader, looks for abnormalities on the scan which shows up everything in the body.
No. It is not a treatment it is a scan. An MRI is a Magnetic Resonance Imaging. MRI are used for imaging tissues.
CT scanning uses radiation while MRI does not
