Many patients often have the question of the difference between a CT scan and an MRI. Although the machines do look similar, what occurs during the procedure is actually quite different.
How a CT scan works:
Computerized Tomography or CT scan works by taking multiple x-rays from different angles then makes use of those x-rays to produce a three-dimensional picture of the organ that requires examination. The computer then examines all the x-rays taken at different angles and collaborates these pictures to generate a three-dimensional model on the computer of the internal organ.
How an MRI works:
Magnetic Resonance Imaging uses and sends magnet and radiofrequency waves into the body. This allows the ability to see inside the body with quality clarity depending on the machine.
MRI or CT, which device is safer?
Generally, both devices are relatively safe. However, there can be certain constraints when performing an MRI since almost all metal devices on the body could cause an issue since an MRI uses a large magnetic field.
CT machines do not have these problems, although, they do expose a patient to radiation. However, this dose of radiation is relatively low. Some CT scans could be inappropriate for pregnancy.
The main differences between an MRI scanner and CT scanner could be defined as follows:
- A CT scan doesn’t show tendons and ligaments whereas an MRI does.
- An MRI is a better tool for the examination of the spinal cord.
- A CT scan is better suited to patients with cancer, pneumonia, abnormal chest x-rays, and bleeding in the brain.
- A brain tumor is more vivid on an MRI.
- Broken bones are more vivid on a CT scan.
- Better images are provided of the lungs and organs in the chest by using a CT scanner.
Both devices have their own advantages depending on the patient’s situation, and can’t exactly be compared. However, making sure the right equipment is used is what should be the priority.
