FDA Clears GE and Toshiba for CT Overexposure
The FDA cleared GE Healthcare and Toshiba America Medical Systems of any blame for the overexposure of hundreds of patients to CT-induced radiation resulting from brain perfusion scans. The FDA’s announcement followed an investigation into whether GE and Toshiba CT scanners provided appropriate protocols for safe usage and whether either manufacturer had modified any of the six hospitals’ protocols to cause the overexposure. The FDA found no violations of laws or regulations by either company.

M.R.I.’s Help Fight High Risk of Cancer
For women with a high risk of breast cancer because of genetic mutations or family history, yearly M.R.I. scans in addition to mammograms and breast exams may save lives, a new study finds. The study, the first to measure survival in a large number of high-risk women receiving M.R.I.’s, found that after six years of follow-up, 93 percent of mutation carriers with cancer were still alive, compared with 74 percent alive at five years in earlier studies. In the new study, all of the women at high risk because of family history were still alive after six years…

Study: CT scans reduce lung cancer deaths by 20% compared with X-rays
Screening smokers and ex-smokers with high-tech CT scans has been shown for the first time to significantly cut deaths from lung cancer, the leading cancer killer, federal health officials said Thursday. A long-awaited study of more than 53,000 middle-aged and elderly people who once smoked heavily or currently smoke heavily found 20 percent fewer deaths among those who underwent annual screening with a procedure known as low-dose helical computed tomography (CT), compared with those who had standard chest X-rays…
