For feature coverage, CBS offered in-house physician Jon LaPook keeping an Eye on Your Health. He warned us about the radiation dangers from diagnostic CT scan machines, whose doses can be 600 times as strong as a chest X-ray. The $800 procedure is safer than invasive angiography surgery for heart patients but the CT machines themselves can be falsely calibrated. Research in the Journal of the American Medical Association found that some scanners are six times more radioactive than others performing the same procedure.
ABC and NBC both filed medical features too, on EMS medevac helicopter fleets. The National Transportation Safety Board held hearings into "the highest fatal accident rate in all of aviation," according to Tom Costello for NBC's In Depth. On ABC, Brian Ross' Investigates told us about so-called "helicopter shopping." Most of the fleets are privately owned and "there is fierce competition" to make the $10,000 flights: even in bad weather or at night, when one helicopter turns down a job on safety grounds, a second medevac will get the call.
