Matter of Time. For all his firsts in heart surgery, Charles Bailey is the first to admit the difficulty of proving the results of coronary operations. He is impatiently awaiting delivery of an X-ray machine which will take pictures at 1/500 sec. and, with radiopaque dyes, will show precisely where and how extensively a coronary artery is blocked-or unblocked. This will make it possible to judge with far more accuracy how much good an operation has done. Thanks to the prospects of such machines, surgeons who have so far held aloof from coronary disease are now showing interest...
...private practice. At the university Dr. Graham made no more than perhaps a tenth of the income he could have commanded from fees. He became an outspoken and effective foe of such evils as fee splitting and ghost surgery. To his scientific achievements he soon added a dependable X-ray technique for diagnosing gall-bladder disease. But his most dramatic accomplishment did not come until...
With the tube in place, Dr. Forssmann climbed two flights of stairs to the X-ray room, and persuaded the radiologist to take a picture as photographic proof that its tip had entered the right side of his heart. The technique, he reported in a learned paper in 1929, would be valuable for studying the blood pressure inside the heart, and for injecting radiopaque dyes to get X rays of the heart, including abnormalities. But his discovery was ignored in Germany. Older men, who should have been wiser, scoffed at Forssmann's catheterization of the heart as a circus...
Patients are getting worried about X rays. Following the National Academy of Sciences' Report to the Public on the biological effects of radiation (TIME, June 25), more and more people have begun to nag doctors and dentists about possible harmful effects. Many have flatly refused to submit to X-ray examination or treatment. Just how safe-or dangerous-are X rays...
Dental. The average dental X ray now delivers 5 r., but this is only to the jaw: the "scatter" radiation reaching the gonads from this is a mere .005 r. in a man and .001 r. in a woman. It would thus take 2,000 X rays to deliver a presumably damaging 10 r. to a man's gonads. Even so, notes the Journal of the American Dental Association, the currently used 5-r. doses are unnecessary. In the same issue, Radiologist Lewis E. Etter of Pittsburgh tells dentists how (by using higher voltages, better filters, faster films, shorter...
