are the experts who operate the machinery and position the patient to get the best image.
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
Are you interested in the high-tech physics of an MRI or the quick diagnostic power of an ER X-ray ?
In radiology, everything is about shades of gray. We use a concept called :
Think of this as a 3D X-ray. A CT scan takes "slices" of the body, allowing doctors to see organs, blood vessels, and complex fractures in incredible detail.
