The Cancer Risk from Low-Level Radiation (LNT) of radiation carcinogenesis. According to LNT, if 1 Gy (100 rad) of exposure gives a cancer risk ., the risk from 0.01 Gy (1 rad) of exposure is ./100, the risk from 0.00001 Gy (1 mrad) is ./100,000, and so on. Thus the cancer risk is not zero regardless of how small the exposure. However, in作者: 爭吵 時(shí)間: 2025-3-22 19:56

Optimization of Radiation Dose in Cardiac and Vascular Multirow-Detector CTCG-gated acquisition is generally higher than that with other CT acquisitions. However, multiphasic acquisitions of other organs (for example liver) may also be associated with a comparable or even higher total radiation, so this large radiation dose is not specific to cardiac CT.作者: 6Applepolish 時(shí)間: 2025-3-24 01:40 作者: Fortify 時(shí)間: 2025-3-24 05:52 作者: ferment 時(shí)間: 2025-3-24 10:24
