Gamma-based imaging proves useful in breast cancer metastases

By Shalmali Pal

Two recent studies have taken a closer look at the role of gamma cameras and gamma probes in tracking the spread of breast cancer. In the first study, Japanese researchers compared SPECT to FDG-PET for detecting bone metastasis to the axial skeleton in breast cancer cases. In the second paper, French authors compared gamma probes for sentinel lymph node detection, which is an important guide for therapeutic choices.

When done correctly, segmentation excludes background regions from analysis, improving accuracy and reducing computation time. But improper segmentation can result in missed information, warn researchers from Duke University in Durham, NC.
