...should probably copyright that Fort Movie idea because Hollywood, which has made a mint selling toys inspired by its movies for decades, is now selling movies based on toys. And, as if this summer's news that Baby Einstein videos won't necessarily send a newborn to Harvard and toys made in China may cause intestinal damage weren't enough to send parents back to good old teddy bears, it turns out toy movies aren't all that great for kids either...
...Andrew Einstein, a cardiologist at the Columbia University College of Physicians and Surgeons, researchers calculated the lifetime attributable cancer risk associated with radiation exposure from a single scan (called computer tomography coronary angiography, or CTCA), based on the patient's sex and age. For example, the lifetime cancer risk following one CTCA was just 1 in 3,261 for an 80-year-old man; that risk jumped to 1 in 284 for a 40-year-old woman, and climbed higher still to 1 in 143 for a 20-year-old woman. At all ages for women, the risk of breast...
...Einstein expects that the new study's findings will have several implications in the everyday practice of medicine. "I think this can reassure a lot of patients that CTCA is a good test-and a safe test particularly for older patients," says Einstein. "On the other hand, for younger women, I think it may affect physicians' thinking in terms of the risk-benefit ratio of the test...
...Because of the potential hazards involved with radiation exposure, Einstein warns patients against attempts to "get pretty pictures of their heart" without a doctor's recommendation. Otherwise, he says, the CTCA can be an excellent noninvasive alternative to the current gold standard test for heart disease, the coronary angiography, which involves threading a catheter from the groin to the heart's blood vessels, and can cause complications such as blood clots, infection and even death. CTCA is also a good substitute for the time-consuming diagnostic tests in use in emergency departments; with CTCA physicians can find out sooner when...
...Down the line, Einstein believes his team's conclusions will boost cardiac diagnostic technology and prompt major manufacturers to improve it. "This is an impetus toward accelerating the pace of research in cardiac CT scans so as to reduce the dose to patients," says Einstein...
