PET scan tracer detects both cancer and lung disease

Stanford’s Sanjiv Gambhir has developed an imaging molecule that can identify pancreatic, cervical and lung cancer early– and, surprisigly, hard-to-detect idiopathic pulmonary fibrosis.  The tracer clings to integrin alpha-v beta-6. In a PET scan, the tracer glows due to radioactivity emissions, which allows doctors to see exactly where the tracer is docked in the body.

A small clinical trial included patients healthy and cancer or IPF patients. The results indicated the tracer is accurate and has disease detection potential.
