Low radiation scans help identify cancer in earliest stages

Tweet

ATS 2013, PHILADELPHIA ─ A study of veterans at high risk for developing lung cancer shows that low-dose computed tomography (LDCT) can be highly effective in helping clinicians spot tiny lung nodules which, in a small number of patients, may indicate the earliest stages of the disease. LDCT uses less than a quarter of the radiation of a conventional CT scan.

Results of the study will be presented at the ATS 2013 International Conference.

Children with obstructive sleep apnea who had a common surgery to remove their adenoids and tonsils showed notable improvements in behavior, quality of life and other symptoms compared to those treated with "watchful waiting" and supportive care. However, there was no difference between both groups in attention and executive functioning, as measured by formal neuropsychological tests.
