The Difference Between MRI and CT Scans-
What is an MRI?
An MRI creates comprehensive images of your body using a powerful magnetic field, radio waves, and a computer. An MRI exam room contains the strongest and largest magnet. The capacity to take images of the brain and spinal cord without utilizing X-rays is what makes MRIs so popular, (which could be harmful). MRIs, on the other hand, can aid in the diagnosis of a wide range of conditions affecting almost any organ system.
The MRI scanner produces a magnetic field around the area being scanned, allowing it to detect tissue and fluids in your body. The MRI machine sends radio waves to a receiver in the device, which is translated into a picture of the body that can be used to diagnose problems. This magnetic force field prevents anything metallic, including jewelry, from entering the machine.
MRI is typically used for:
- Brain
- Joints
- Ankles
- Heart
- Wrists
- Blood vessels
- Breasts
How Does MRI Work?
Magnetic resonance imaging (MRI) uses powerful magnets to generate a strong magnetic field that causes protons in the body to align with it. Protons are activated and spin out of equilibrium when a radiofrequency current is pulsed through the body, pushing against the magnetic field’s pull. The energy produced as the protons realign with the magnetic field can be detected by MRI sensors when the radiofrequency field is switched off. The quantity of energy released as well as the time it takes for the protons to realign with the magnetic field vary depending on the environment and the chemical makeup of the molecules. On the basis of these magnetic properties, physicians can detect the difference between different types of tissues.
A patient is placed inside a powerful magnet to obtain an MRI image and must remain completely motionless throughout the imaging process to avoid blurring the image. To accelerate the speed at which protons realign with the magnetic field, contrast medications (typically containing the element gadolinium) may be given intravenously to a patient before or during the MRI. The brighter the image, the faster the protons realign.
What is CT scan?
A CT scan (also known as a CAT scan) creates cross-sectional images of the body using computers and rotating X-ray devices. A CT scan depicts soft tissues, blood arteries, and bones in great detail. They vary from conventional imaging tests in that the visuals you see are generated by computer calculations rather than photographs. The image contains more information than a standard X-ray. This can assist your doctor in determining whether your brain, spinal cord, blood vessels, or heart are abnormal.
CT scan is typically used for:
- Tumors
- Cancer monitoring
- Finding internal bleeding
How does CT work?
They employ a small X-ray laser that rotates around a certain portion of your body. This gives you a variety of photographs from various perspectives. A computer creates a cross-sectional image using this information. This two-dimensional (2D) scan reveals a “slice” of the inside of your body, similar to how one piece of bread shows one slice of bread.
A number of slices are made by repeating this technique. These scans are stacked on top of each other by the computer to build a detailed representation of your organs, bones, and blood vessels A surgeon, for example, might use this type of scan to prepare for surgery by looking at all sides of a tumor.
Risks
When used, both CT scans and MRIs have some dangers. The dangers vary depending on the type of imaging and how it is performed.
The following are some of the risks associated with CT scans:
- Dose of radiation
- Harm to unborn babies
- Possible reaction to the usage of dyes
MRI risks include:
- Loud noises from the machine produce hearing impairment
- Possible reactions to metals due to magnets
- Increase in body temperature during long MRIs
An MRI is excellent at obtaining images that aid doctors in determining whether or not there are any abnormal tissues in the body. An MRI image is more detailed than a CT scan. To be able to create such detailed visuals.
