Explanation:
Detailed explanation-1: -Dense bone absorbs much of the radiation while soft tissue (muscle, fat, and organs) allow more of the x-rays to pass through them. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray, and air appears black.
Detailed explanation-2: -A CT scan, or computed tomography scan, sends radiation through the body. However, unlike a simple X-ray study, it offers a much higher level of detail, creating computerized, 360-degree views of the body’s structures. CT scans are fast and detailed. They take longer than X-rays but are still fast (about one minute).
