Software AIDS in Lung Cancer Detection

Researchers at the University of Michigan Comprehensive Cancer Center are developing computer aided diagnosis methods to make lung cancer diagnosis easier.

Based on computer-assisted breast cancer diagnosis experience, Dr. Lubomir Hadjiyski, research assistant professor of radiology at the school said radiologists stand to gain from the extra eyes.

Radiologists with computers are able to detect more cancers than radiologists by themselves, Hadjiyski said. We expect that CAD for lung cancer can achieve similar results.

The computer analyzes the images with computer-vision techniques specially designed for a given type of cancer or disease. At the same time, the radiologist examines the images and evaluates the likelihood of cancer. The radiologist then compares the two results and makes a final decision.

Hadjiyski presented results of the project Sunday at the Radiological Society of North America's annual meeting in Chicago.
