Arteriograms (Xray still photos of arteries that have been flooded with radiopaque dye) help, but they are not always reliable: the "flooding" technique often fails to fill the arteries with enough dye, and still pictures do not clearly separate small vessels that are superimposed on each other. One of the major breakthroughs at last week's AHA meeting came when the Cleveland Clinic's Drs. Earl Shirey and F. Mason Sones Jr. demonstrated a diagnostic technique that seems likely to improve on the arteriogram-a method of coordinating the ray, a specially designed catheter and a movie camera...
Monitoring the operation through an image intensifier-a refined fluoroscope that produces an X-ray image 1,500 times Drighter than the old-style fluoroscopic screen-Drs. Sones and Shirey then release a tiny amount of radiopaque dye through the catheter into the aorta in order to locate the spot at which right and left coronary arteries join the circulation's main stem. "The rest," says Sones, 'requires only a little bit of simple dexterity." The catheter is successively slipped into both coronary arteries, and small injections of dye (2 cc. to 5 cc.) are sufficient to silhouette...
...Bertram Selverstone has devised a daring and ingenious technique. First, Dr. Selverstone opens the way to the Circle of Willis by taking out a big flap of bone from the skull. (An arteriogram-an X ray of the brain's blood vessels involving the injection of radio-opaque dye into the patient-will have already spotted the site of the aneurysm.) Then, using an artist's airbrush, Selverstone sprays the aneurysm with a mixture of plastics that combine to form a coating similar to Saran Wrap. This is tough, but too thin to give full protection against further...
Among them all, as the camera watches, moves man: an animal among animals, swallowed in nature's hungry womb, nourished with nature's wisdom and delight. Like dye stains through a tissue, the patterns of nature seep through African society. The force of the volcano imbues the man who smokes a pipe. The passion of the wooing crane inflames the maid who imitates its mating dance. The example of the hornbill, a bird that jealously mud-walls its mate in a tree for as long as three months at a stretch, is incorporated in the marriage laws...
...placed an entire airplane in a huge mechanical jig, is literally shaking it to test its vibration tolerances. A whole wing section complete with engines has been taken off the production line, is being twisted and bent to destruction to check its strength. All critical parts are being dye-tested for surface cracks, X-rayed for hidden flaws in the metal. Most rugged test of all: Lockheed pilots are flying a minutely instrumented Electra through the extremely turbulent "Sierra wave'' over California's Sierra Nevada mountains, are slamming into the wind-shears at high speed...
