A quick recap on medical scanners used at my clinic. Medical scanners allow doctors to see inside patients' body. This painless procedure involves a combination of X-rays / magnetic fields and a computer to create images of patient' organs, bones, and other tissue. It shows far more detail than a regular X-ray.
Both MRI and CT scans provide diagnostic images of the inside of patients' body. They, however, accomplish this task in distinctly different ways.
MRI scan (Magnetic Resonance Imaging) allow doctors to see inside patient's body in great anatomical detail. It involves a combination of X-rays / magnetic fields and a computer to create images of patients' organs, bones, blood vessels, nerves, etc. It shows far more detail than a regular X-ray. MRI is generally used to scan soft tissue.
CT or CAT scans (Computerised Tomography), combine data from several X-rays to produce detailed images of structures inside the body.
CT scans typically take diagnostic images more quickly compared to MRI. CT scan can usually be completed in less than 5 minutes, while MRI takes about of 30 minutes.
