DIFFERENCE BETWEEN CT SCANS AND MRI

 

You might have heard some time or another, CT scan and MRI and must have always wondered what is the difference between the two.

Though both are methods for imaging internal body parts, and also have an almost similar use, the way they are produced is different. CT scans use X-rays while MRI uses strong magnet waves and radio waves.

A CT scan or the CAT scan stands for Computerized Axial Tomography, wherein a large X-Ray machine called a CT scanner sends the image to the computer.

MRI or Magnetic Resonance Imaging uses radio waves and magnets to create images. In this scan, the constant magnetic field and radio waves bounce off the water molecules and fat cells in the patient’s body.

Though CT scans are very common as they are cheaper than MRIs, MRI produces detailed and accurate images of the body.

The very common uses for a CT scan include examining or looking for a tumor, bone fractures, internal bleeding, cancer development, and response to a particular treatment.

An MRI on the other hand is used when doctors need to diagnose any issues with bones, organs, and joints including ankles, breasts, brain, heart, joints, wrists, blood vessels, etc.

CT scans and MRIs both are very safe procedures however they pose significantly different types of risks.

A very little quantity of radiation is given to a patient during a CT scan, but doctors often do not view this as dangerous.

Radiation is not used in MRI scans. However, they do employ powerful magnetic fields. Any type of medical implant, such as a pacemaker, insulin pump, or cochlear implant, must be disclosed to technicians. People typically wear earplugs or headphones to reduce the noise during MRI scans because they make loud noises. MRI scanners may be uncomfortable for claustrophobic people, but there are now various varieties of open MRI scanners that can help with this issue.

Your doctor will recommend the scan that he requires to analyze your need and thus a very effective imaging procedure

The Revolutionary World of MRI Scans: Unlocking the Secrets Within

Image
  MRI (Magnetic Resonance Imaging) scans have revolutionized the field of medical diagnostics, enabling detailed visualization of the human body without invasive procedures. This non-invasive imaging technique utilizes magnetic fields and radio waves to create detailed images, providing crucial insights into various medical conditions. In this blog post, we will explore the fascinating world of MRI scans and their significance in modern medicine. Understanding MRI Scans: MRI scans utilize powerful magnets and radio waves to generate detailed images of organs, tissues, and structures inside the body. By manipulating the magnetic properties of hydrogen atoms within the body, MRI scans create a comprehensive map of the targeted area. Unlike X-rays or CT scans, MRI does not involve any ionizing radiation, making it a safe and preferred choice for both patients and medical professionals. Unveiling Complex Anatomy: MRI scans offer remarkable clarity and detail, providing healthcare p...

5 Things you should know before you get MRI

  An MRI is done when your doctor prescribes you but having heard the abbreviation, you might have always wondered what it stands for. An MRI or Magnetic Resonance Imaging uses radio waves and powerful magnets. These waves, clash with the water and the fat cells that are present in your body and thus send the data to the computer which then sends to the computer for the doctors to look at. Therefore, in simple terms, MRI is a procedure that lets doctors know what is happening inside your body without performing any invasive procedures.   1 .   Let your doctor know all your allergies and phobias, conditions Having an MRI is lying in an enclosed tube-shaped machine for a varying amount of time. This means if you are claustrophobic, this might result in an anxiety attack or anything further worse. It is always better to talk to your doctor about it ahead of time. Not just phobias, but also consult about each of your conditions. 2.   MRIs are safe Yes, it is an...
