MRI based on a sugar molecule can tell cancerous from noncancerous cells

Imaging tests like mammograms or CT scans can detect tumors, but figuring out whether a growth is or isn’t cancer usually requires a biopsy to study cells directly. Now results of a study suggest that MRI could one day make biopsies more effective or even replace them altogether by noninvasively detecting telltale sugar molecules shed by the outer membranes of cancerous cells.
