US researchers devise new technique to detect cancer from CAT scans

December 19, 2018

The new approach is expected to offer a non-invasive, easy, accurate and cost-effective option for determining if certain tumours are cancerous or not.

Lung-cancer screenings typically involve interpretation of suspicious nodules on a CAT scan by a radiologist.

Patients have to then undergo invasive and costly tests such as surgical biopsies for the nodule assessment.

Case Western’s new technique analyses the regions outside the tumour and the surrounding blood vessels to identify whether the nodules are cancerous. This avoids deeper examination or cutting.
