MRI Technique for Detecting Cancer Could Replace Biopsies

The results of the study were published on online, in the journal Nature Communications on March 27, 2015.

Xiaolei Song, PhD, the lead author on the study, said, “This is the first time a property integral to cancer cells, rather than an injected dye, has been used to detect those cells. The advantage of detecting a molecule already inside the body is that we can potentially image the entire tumor. This often isn’t possible with injected dyes because they only reach part of the tumor. Plus, the dyes are expensive.

The team will next try to distinguish additional types of cancerous tumors from benign masses in live mice. If they succeed it could lead to earlier detection of cancer, new methods to monitor response to chemotherapy, and new ways to guide biopsies that may eventually make some biopsies unnecessary.
