Bone SPECT superior to FDG PET for detecting bone metastases in breast cancer
...rs, due to these differences in method, bone SPECT images
can reveal the location of bone metastases, whereas PET cannot. In addition, bone SPECT can detect where bone is being regenerated after destruction by tumor cells. For the study, the researchers analyzed the findings in a total of 900 bones in 15 pa...

'Virtual colonoscopy' effective in finding most polyps but may miss small ones
...CT scanning uses computers and software to display images
of the colon as if the viewer were seeing the inside of it through an endoscope, the instrument used in traditional colonoscopy. It does not require sedation, although it does require the same bowel-cleansing preparation as the older method. The revi...
