...study published today in the Journal of the American Medical Association shows that radiation from a high-resolution cardiac CT scan-the newest, noninvasive test for detecting heart disease-may slightly raise patients' lifetime risk of developing cancer. In general, the study found, the elevated risk of cancer was greatest for women and younger patients...
...attributable risk of cancer per CTCA scan was low, ranging from 0.02% (for an 80-year old man, with the dose-reduction strategy) to 1% (for a 20-year-old woman, with a regular heart and aorta scan). The benefits of CTCA are that it is noninvasive, quick (the test takes about 10 minutes), requires that the patient ingest less contrast dye than with other scans and can be performed immediately in an emergency room when someone is admitted with chest pain. According to the study's authors, emergency departments evaluate about 6 million patients each year for chest pain...
...calcified or non-calcified plaque," says Dr. Norman Lepor, a professor at UCLA's Geffen School of Medicine, referring to the tell-tale build-up on artery walls that signifies heart disease. Lepor says that CTCA gives off no more radiation than the routinely used diagnostic nuclear stress test, which also detects plaque deposits, but only those that are big enough to block 70% of the artery. "The risk-benefit assessment is in favor of cardiac CT to be used in a judicious fashion," says Lepor, who describes good candidates for the scan as male, over age 40 with...
...both parties fail to come to terms before Aug. 15, Reese could test the waters of free agency. Whatever the outcome of his contract talks, Reese plans to cut ten pounds, work on his explosive step, and adapt to a less-scrappy style of defense to better suit his 5’11 frame...
...candidate himself, who recently returned from Iraq, did not indicate any misgivings about his stance in favor of the Iraq invasion and the subsequent military buildup. Instead, he framed it as a test of national resolve, and one that is of historic proportion. "We must act boldly and with confidence that history has not yet assigned us a challenge that we cannot meet successfully," he said. "Though we regret the mistakes we have made in this war, they must not cause us self-doubt. We must learn from them, as Americans have always learned from our mistakes, and fight smarter...
