Bone SPECT superior to FDG PET for detecting bone metastases in breast cancer
...s, 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 patients with breast cancer who underwent both SPECT and PET. They found that SPECT had a sensitivity...

Can hospital data detect poor performing doctors?
Can routine hospital data be used to detect
poor quality service delivery among surgeons? For over 20 years, routine data sources such as the hospital episode statistics have been widely perceived as being of little value because of problems with completeness and accuracy, and the Department o...
