Bone SPECT superior to FDG PET for detecting bone metastases in breast cancer
...er Center Hospital in Japan. FDG PET is an imaging technique
based on the increased metabolism of glucose in tumor cells. SPECT is atype of nuclear medicine scan that detects special radioactive elements administered to the patient by the physician. According to the authors, due to these differences in method,...

'Nanoshells' simultaneously detect and destroy cancerous cells
...biomarkers on the surface of the cancer cells. The technique
can be readily extended to target other types of cancer or disease processes that have known surface markers.The additional ability of the particles to absorb light is used to generate heat, which then destroys the cancer cells. "Nanoshells are very ...
