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.

The "OG" of radiology. It’s best for looking at dense structures like bones or finding fluid in the lungs. It’s fast and cheap, but it uses a small amount of ionizing radiation. Radiology 101: The Basics & Fundamentals of Ima...

Radiology is the bridge between a patient’s symptoms and a doctor’s diagnosis. By mastering these fundamentals—the types of scans, the way density looks on screen, and the importance of safety—you’re well on your way to understanding how modern medicine solves its greatest mysteries. In the world of imaging, we live by

are the experts who operate the machinery and position the patient to get the best image. It’s best for looking at dense structures like

Not every "scan" is the same. Doctors choose a specific type of imaging based on what they are looking for:

This uses high-frequency sound waves. Since there is no radiation, it’s the go-to for pregnancy, but it’s also great for looking at the heart (echocardiograms) and gallbladder. 2. Understanding "Density" (The Black and White)

At its heart, radiology is the specialty of "seeing the unseen." We use different forms of energy—like X-rays, sound waves, and magnets—to create a map of the human body. Here is the foundation you need to understand how it all works. 1. The Big Four: Common Imaging Modalities
