A CT scan uses what’s called “ionizing” radiation. It’s powerful enough to pass through your body to create clear images on a computer. This type of radiation could raise your chances ofcancerat some point in the future. But it’s important to remember that ionizing radiation is around...

The X-ray exam also may be modified to reduce the radiation. Often the risk of not having a necessary X-ray can be greater than the risk of the radiation. It is safe to have X-ray tests while breastfeeding. The radiation does not affect the milk or the baby, and breastfeeding is ...
Hepatocellular carcinoma (HCC), the most common primary liver cancer, is a significant global health burden. Accurate imaging is crucial for diagnosis and
When smoke enters the ionization chamber, it disrupts this current -- the smoke particles attach to the ions and neutralize them. The smoke detector senses the drop in current between the plates and sets off the horn. Speaking of alarms, whenever the words "nuclear radiation" are used an ala...
X-rays are a form of electromagnetic radiation, similar to visible light but with much higher energy. They consist of photons, which are particles without mass or charge, and their energy allows them to penetrate materials and create images of internal structures in various applications such as ...
Additionally, post-processing techniques can also be used to improve diagnostic capabilities of traditional CT and reduce complications such as contrast reactions and excess radiation exposure. One of these post-processing techniques is deep learning (DL), which is a sub-branch of artificial ...
Appropriateness of performing spine and pelvic radiographs in patients with axPsA without axial symptomology could be debatable because X-ray does not always detect sacroiliac involvement; there are no international recommendations in this context, and also because of the exposure to ionizing radiation....
Second, we wished to discuss the different ways of reducing CT radiation dose by considering both behavioral and technological factors. Among the behavioral factors, limiting the scan coverage area is a straightforward and effective way to reduce the dose. Improvement of technological factors relies ...
