What are the differences between MRI and CT scans?

What are the differences between MRI and CT scans?

MRI (Magnetic Resonance Imaging) uses magnets and radio waves to create detailed images of organs and tissues, while CT (Computed Tomography) uses X-rays to produce cross-sectional images. MRI is better for soft tissues, while CT is faster and often used for bone injuries.

Which one is safer?

Generally, MRI is considered safer as it doesn't use ionizing radiation, unlike CT scans. However, MRI is not suitable for patients with certain implants or devices.

How long does each scan take?

An MRI scan typically takes 30 to 60 minutes, while a CT scan is much quicker, usually completed in about 10 minutes.

Are there any side effects?

MRI has minimal side effects, but some may experience claustrophobia or discomfort from the machine. CT scans involve exposure to radiation, which carries a small risk.

When should I choose one over the other?

Choose MRI for detailed images of soft tissues, like the brain or muscles, and CT for quick assessments of bone injuries or internal bleeding.
