New 3-D X-ray Detects Breast Cancer Early Sep 18, 2008
However, its use in breast imaging is limited by the radiation dose delivered to a radiosensitive organ such as the breast. A new CT technique has allowed scientists to overcome this problem. (Newsmax)
Mailman School PH study finds increase in thyroid diseases risk from exposure at Chernobyl Feb 20, 2008
Thyroid cancer is one of the most radiosensitive tumors when exposure occurs at young ages. Previous studies showed that the risk of thyroid cancer increased with radiation dose from radioactive iodines, but the effects of radiation on benign thyroid diseases has been largely unknown. (EurekAlert!)
Appropriate timing in the use of breast shields in children can further reduce MDCT radiation dose Feb 13, 2008
It's important for radiologists to limit dose in CT, especially to children, and especially to radiosensitive regions, such as breast tissue; and radiologists should be familiar with strategies to do this, said Donald P. Frush, MD, lead author of the study. Two strategies are breast shielding, and the other is automatic tube current modulation (ATCM). (EurekAlert!)
New health technology is bringing new risks Jul 20, 2007
The same amount of radiation which a woman receives, she's more likely to develop cancer than a man," Einstein said. Young women have a 1-in-143 chance of developing cancer after getting just one scan, according to the study, while a young man has a 1-in-686 chance. Experts say the findings not only warn doctors against ordering too many scans for patients who don't need them, but should also discourage people from getting scans on their own without advice from a doctor. Some imaging centers... (San Francisco Chronicle -- Technology)
Radiographers attend safety course Jul 17, 2007
"The relative risk of these organs during examinations yields high effective doses thus exposing the most radiosensitive tissues in the field of view, including the abdomen and pelvis to higher risk," he emphasised. He said since examinations were indispensable, the principles of justification and optimization had to be considered seriously when such examinations were being recommended. (Ghana Web, Ghana)
