What is the difference between MRI and CAT scans?
MRI is Magnetic Resonance Imaging and a CAT is a computerized X Ray (Computer Assisted Tomography)
MRI will work fine in case of diagnosis of soft tissues and CT will work fine for bony structures and inner ear analysis.
Also MRI do not use any radiation it is based on magnetic effect so less side effects compared to CT which uses X- rays.
MRI is very much costlier compared to CT.
MRI is problematic in case if the patient is having some metallic implant, which will cause interference with the magnetic field.
In order to determine any hairline crack then MRI would be preferred compared to CT.
What field includes CAT computerized axial tomography scans and MRI magnetic resonance imaging scans as diagnostic tools?
CAT scans and MRI scans are useful for a wide variety of medical investigations; the MRI in particular is very useful for neurological examinations, since it is otherwise very difficult to examine the brain in any detail. CAT scans can be used for all sorts of things, to investigate illness or injury in any part of the body. I had one recently for a kidney stone.
CT Scans stands for 'computed tomography scans' create images of the inside of the patient's body and take 360-degree photographs of the internal organs, spine and vertebrae. This imaging technology is the best technology for looking at the spine and vertebrae. MRI- MRI stands for 'magnetic resonance imaging' is different from CT Scan. MRI technology combines a powerful magnet with radio waves which takes the place of the X-Ray wave. Technologist uses the computer to…
3T MRI scans are scans done using twice the magnetic field strength. This is a physical difference. The stronger magnet allows us to see more information in the same time. So a 3T scan is simply twice as good, at least 4 times as fast and also delivers more radiofrequency RF energy during the scan. This means it sometimes feels warm inside the scanner. But to most patients this is a unimportant difference. The true…
They are normally used as tracers. A small amount (Non lethal!!!!!) of a radioactive substance is put into the patient and by monitoring the radioactivity emitted it can be traced where the radioactive substance has moved to. It is also used in PET scans (Positron emission tomography) and MRI scans )magnetic resonance Imaging) possibly also used in CAT scans, I don't know how they work though.
If you have metal in your body you can not have an MRI Scan because the metal will not perform its job properly. Especially if the metal is magnetic, in which case the MRI can literally tear the object out of your body. Additionally there are some signatures that an MRI can't pick up and require a CT scan.
