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.

To do CAT scans and MRI scans on people so you can diagnose them with a disease

The field is known as Radiology or Diagnostic Imaging.

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 manipulate the magnetic elements. This technology provides the detailed picture of the inner structures of the patient's body. Unlike X-Ray technology MRI do not involve radiation.

CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.

It depends on what you want to know? X rays,MRI scans,CAT SCans are all things that can help teach us the things about the body.

Scratch-resistant lenses, cordless power tool, CAT and MRI scans, and freeze-dried food

it can scan very clearly

MRI scans are used to find tumors in the brain and abnormalities of joints. They can also be used for female pelvic problems and to diagnose men's prostate problems.

they have only good benifets

MRI scans look at the inside of the human body. The machines can be a little loud due to the magnetic activity used to produce the images of the inside of the body.

The purpose of an MRI machine is visualize the internal function and structure of the body. A CT scan uses tomography to digitally process the inner part of an object to create a series of two dimensional images taken from a single axis of rotation.

the answer for the crossword puzzle is origin

There is a difference that you might find out one day...

Anything that doesn't require them to cut you open to take a look. Examples are X-rays, CAT scans, sonograms, MRI, etc.

In general, MRIs have MUCH more detail to them. Almost as if you are looking at a real anatomical specimen.

people might not be able to into the machine

CAT: Common Admission Test MRI: Magnetic resonance imaging

Methods of detecting cancer include X-rays, thermography, ultrasound, MRI scans and PET scans.

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 difference is the increased diagnostic capability of 3T MRI. For instance breast lesions are seen 100% at 3T but only 90% at 1.5T. In the case of MS we usually see 37% more lesions in the same patient with the same scans. However - we can sometimes see up to 300% more lesions. In my experience 3T MRI is superior to 1.5T MRI in most cases. We us 1.5T OPEN BORE MRI for our larger patients and claustrophobic patients but in most patients we find that 3T is superior to 1.5T. We offer both to our patients and are one of the few facilities in the world that allows the patient to choose.

Techniques used to measure such factors include electroencephalograms (EEGs), magnetic resonance imaging (MRI), and computerized axial tomography (CAT) scans.
