All x-ray imaging is based on the absorption of x rays as they pass through the different parts of a patients body. Depending on the amount absorbed in a tissue such as muscle a different amount of x rays will pass through and exit the body. The amount of x rays absorbed contributes to the radiation dose to the patient. During conventional x-ray imaging, the exiting x rays interact with a detection device and provide a 2-dimensional projection image of the tissues within the patient's body - an x-ray produced photograph called a "radiograph.
CT scans exposes you to more radiation than regular x-rays. Having many CT scans over time may increase your risk for cancer. The risk from any one scan is small.
Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
