Two new scanning techniques which make use of a computer system may improve diagnostic accuracy of radioisotope scanning.

The two techniques, called transverse section scanning and transmission scanning, actually are byproducts of a computer program being conducted in the Department of Radiology at the University of Pennsylvania. The program is supported by the US Public Health Service and the US Atomic Energy Commission.

Initial clinical studies indicate that these techniques may be applicable in detecting lesions of the brain, liver, lung, and thyroid.

David E. Kuhl, MD, assisted by Roy Q. Edwards, project engineer, began experimenting several years ago with a computerized radioisotope scanner with a dual detection system. The instrument was designed to evaluate rectilinear, cylindrical, and sectional scanning, and to investigate other possible modes of motion scanning. It was from these investigations that transverse section and transmission scanning evolved.
