When Do You Know if an Xray Is Alarmed
Many patients are concerned about receiving radiation from CT Scans or X-rays. Even the discussion "radiation" can exist intimidating, every bit we often associate it with radiations sickness from atomic bombs or disasters at nuclear power plants. Just don't worry – the radiation used in medical imaging will not make y'all glow in the dark and volition not harm you in small doses.

Ionizing Radiation is the emission of high-free energy electromagnetic waves that move subatomic particles. This type of radiation carries enough directly energy that it causes electrons to detach from atoms or molecules, which is called ionization .
In medical imaging, X-ray applied science emits these loftier-energy waves (similar to light) that pass through the body and generate images of structures within the body. These waves are absorbed in different amounts by different structures of the body. The denser an object in the body is, the more than the waves will exist absorbed. For case, x-rays pass easily through soft tissue and organs, but are captivated by highly dense structures like bones. Because the bones take absorbed nigh of the waves, they show up as white "shadows" on the radiograph.
Medical imaging exams that apply radiation include traditional ten-rays, CT, nuclear imaging exams, or fluoroscopy. However, in that location are other types of imaging exams that use technology that does non emit radiation. MRI and Ultrasound scans do not use radiations at all, and therefore practice not pose any increased risk of cancer.
