"Ours is the first population-based study to capture data on every CT scan to an individual during childhood or young adulthood and then measure the subsequent cancer risk." Despite the elevation in cancer risk, these two malignancies are relatively rare and the actual number of additional cases...
CT Scans and Lung Cancer Small or slow-growing nodules (小结节)discovered on a lung scan are unlikely to develop into tumors over the next two years, researchers reported on Wednesday. The findings reported in the New England Journal of Medicine, could help doctors decide when to do more agg...
It depends on your age, gender, and the part of your body that's being scanned. Overall, your odds are very low -- the chance of getting a fatalcancerfrom any one CT scan is about 1 in 2,000. Some organs are more sensitive to radiation than others. It tends to do more damage to...
WASHINGTON (CBS/AP) - A special type of CT scan can detect lung cancer early enough to save some lives, the National Cancer Institute announced Thursday - the first evidence that a screening test may help fight the nation's top cancer killer. At issue are controversial spiral CT scans, whe...
CT scans in cancer fears New evidence of a "substantial cancer risk" from CT scans is reported in the Lancet Oncology in October. At Columbia University researchers have calculated that the radiation produced from an annual scan, risks a one in fifty chance of death. "The risks of full ...

1. F-FDGPET实体肿瘤疗效评价标准:欧洲癌症研究和治疗组织(European Organization for Research and Treatment of Cancer, EORTC)于1999年提出了第1个基于实体瘤代谢反应的PET疗效评价标准,通过测定SUV的变化将治疗反应分为完全代谢缓解(complete metabolic r...
Posteroanterior (PA) and lateral chest radiographs were obtained for further evaluation. 为进一步评估拍摄了胸部正侧位片 Following the radiographic results, a contrast-enhanced CT scan of the chest was performed. Coronal, axial, and sagittal images in ...
Cancers occurring in the mouth, nose, and throat are on the rise in the U.S., especially in younger people. About 60,000 new cases are diagnosed every year, with one in five cases occurring in people younger than 55, according to the American Cancer Soci
The report found cancer risk grew with each scan received, and there was an elevated risk even in those who received only one CT, formerly called a CAT scan. 以前的研究提出了对于CT扫描增加致癌风险的担忧;这份报告则提出了第一个关于这种联系强度的直接证据。它研究了英国国民健康服务(National Health...
