What is the Difference between ct scan and mri?

Answer 1

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.

Answer 2

They are the same thing. CAT stands for Computerized Axial Tomography which was later changer to just CT or rather Computerized Tomography. The scanners originaly only did axial images (referring to the plane of the image) but later became able to do other planes such as coronal or saggital imaging and can now do anything with the block of information it collects.

Answer 3

Insight Medical Imaging offers reasonably priced MRI exams. MRI diagnostic imaging uses electromagnetic fields to produce images. Using radio frequencies, magnetic fields and computers Insight Medical Imaging can produce cross-sectional images of the soft tissues in the body. These images can aid in the diagnosis of medical conditions. Due to the electromagnetic fields, consult with your doctor or MRI technologist to determine if MRI examinations are safe for you.

Answer 4

CT scan (also referred to as CAT scan) means "Computer Tomography" and PET scan means "Positron Emission Tomography". They are related to each other but are different forms of imaging technology used in medicine. A PET scan uses nuclear medicine imaging to scan body functions and create a 3-D picture of things including metabolic information. CT scans is a more in-depth type of x-ray that can outline the bones more accurately and provides anatomic information.

Answer 5

mri (magnetic resonance imaging)

ct (computerised tomography)

ct-scanners produce a special sort of x-ray which builds up a 3D image of the inside of the body. this scan is painless and takes about 30 minutes. you hae to lie on a couch which moves through a short tunnel where the scanner is housed.

mri-scanners use magnetic fields rather than x-rays to build up a series of cross sectioned image of the body. this scan may take longer than a ct scan. you will be asked to lie very still on a couch inside a metal cylinder. this maybe uncomfortable and some people will find it chlostrophobic. it is also very nooisy but some people are given headphones or earplugs.

Answer 6

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.

Answer 7

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.

Answer 8

CT and MRI are both scan tests. CT scan however uses specialized x-ray machine. For MRI, the test takes 30-45 minutes using magnets and radio waves to capture images.

Answer 9

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

Answer 10

An MRI scan is different from a CAT scan as it uses magnets and radio frequencies as opposed to X-rays to generate images of the brain.
