What Is The Difference Between X-rays, CT scans, And MRIs?
🔸 X-rays:
Used for routine examinations
Quick and inexpensive
Most common and widely available
Produces a two-dimensional (2D) image
Used to detect fractures, pneumonia, and some cancerous tumors
Contains a small amount of radiation
🔸 Computed tomography (CT) scan:
More accurate than x-rays
Produces a three-dimensional (3D) image
Used to diagnose diseases of organs, tissues, and bones
Captured 360-degree images
More comprehensive than x-rays
Significantly higher radiation than x-rays
🔸 Magnetic resonance imaging (MRI):
More accurate in some cases
Produces a three-dimensional (3D) image
Used for conditions related to the spine, brain, muscles, and abdomen
Relies on powerful magnets and radio waves for imaging
Contains no radiation
Expensive and time-consuming during imaging
🔸 The Difference Between MRI and PET Scan
A PET scan is used to measure the body's metabolic processes after a radioactive substance is injected.
It is used to detect cancers and their spread.
It helps evaluate the effectiveness of cancer treatment.
