are the medical doctors who interpret those images, hunt for abnormalities, and provide a diagnosis that guides the patient's treatment. 4. Why We Use "Contrast"

A common misconception is that the "person taking the picture" is the doctor. Radiology 101: The Basics & Fundamentals of Ima...

This uses powerful magnets and radio waves (no radiation!). It is the gold standard for "soft tissues" like the brain, spinal cord, ligaments, and tendons.

are the experts who operate the machinery and position the patient to get the best image.

In the world of imaging, we live by the principle: As Low As Reasonably Achievable. This means we always use the lowest dose of radiation necessary to get a clear diagnosis, and we opt for non-radiation options (like Ultrasound or MRI) whenever possible, especially for children. Why We Use "Contrast" A common misconception is

Sometimes, the "shades of gray" are too similar to tell apart. That’s where comes in. By injecting a special dye (usually iodine or gadolinium) or having a patient drink it, we can make blood vessels or the digestive tract "light up" on the screen, making it much easier to spot a blockage or a tumor. 5.
