COMPETING SYSTEM--HEI 7) New Cancer Scanner May Avoid Need For Biopsies [01/14/99; Reuters News Service] LONDON (Reuters) - A revolutionary imaging device developed by a U.S. scientist could offer a less traumatic means of cancer screening, avoiding the need for painful biopsies. The three-dimensional imaging technique -- called Hall Effect Imaging (HEI) -- uses electronic emissions to spot differences between healthy and diseased tissue, New Scientist magazine said Wednesday. ''What I'm hoping to have is something as sensitive and specific as MRI (magnetic resonance imaging) but with the speed of ultrasound,'' the inventor, Han Wen, based at the National Institutes of Health in Maryland, told the magazine. Breast cancer tumors give off a different electrical signal to healthy tissue. The new imaging technique uses ultrasonic emissions to highlight those differences.
