CT and MRI are two often used diagnostic tools in medicine today. They are, however, very different and it is important to know the differences between the two when discussing diagnostic plans with a doctor.
A CT scan (also know as a "CAT scan" or Computerized axial Tomography) was invented by Sir Godfry and Robert Ledley in 1975. It was the first diagnostic tool capable of seeing beyond what the X-ray can see by looking at soft tissue within the body. A CT scan uses only one beam of radiation, unlike the older technology of an X-ray. A major concern over prolonged, continued exposure of CT scans is damage to an individual's DNA. CT scans are still used, however, for some tests and is safe for occasional use. The risks should be discussed with the medical professional the patient's questions are answered completely prior to testing.
MRI (Magnetic Resonance Imaging) scans are relatively new in the diagnostic medical testing process. The MRI was developed in 1971 by Dr. Raymond V. Damadian. The first MRI took place in 1977.
Doctors now use MRI imaging technology regularly. MRI scans allow for review of tissues in the body, as well as to look for tumors or blockages, while emitting zero radiation and providing extremely detailed images.
MRI is considered by many doctors to be the standard for imaging tissues and the entire body. MRI provides very detailed images as opposed to CT and, more importantly does not result in any radiation exposure.
A mobile MRI allows for a location that may not have an MRI unit, or if the standard MRI unit is in need of repair, access to the necessary diagnostic tools to diagnose their patients. A mobile MRI is often housed in a dedicated trailer that can go anywhere and stay in place for a long period of time, if needed.
While some may have concerns about using a mobile MRI , there should be zero concern from patients or medical professionals. While a mobile MRI is not in a fixed location, they are required to meet the same high maintenance standards as fixed MRI. A mobile MRI can also provide whatever level of medical imaging is required by the hospital or imaging center.
