摘要

In drab offices at the cleveland clinic, 11 technicians toil at computer consoles and painstakingly analyze videotape of a peek inside the arteries of ailing heart patients. At stake is the fate of experimental drugs with the potential for billions of dollars in sales. The lab is the brainchild of cardiologist Steven Nissen, who has convinced drug companies that an exotic artery imaging technology called intravascular ultrasound (IVUS) can help them get their products to market much faster. The technique involves threading a miniature ultrasound probe into the coronary artery with a catheter, then taking a three-minute video inside. Technicians use the resulting images to measure the volume of plaque in a segment of an artery; a standard angiogram merely measures obstructions to blood flow. "This has the capacity to cut drug development time in half," says Nissen.
