MRI and FDG-PET/CT recommended for advanced breast cancer
FDG-PET/CT should be used in conjunction with breast MRI as a complementary imaging tool for patients with locally advanced breast cancer, because the hybrid imaging modality can detect distant metastases outside the field-of-view of breast MRI, according to researchers from Stanford University in California.

PET/CT shows its worth in cervical carcinoma
American Cancer Society statistics estimated 11,500 new cases of cervical carcinoma and total deaths of 3,670 from the disease in 2007. With these numbers, FDG-PET/CT should become an integral part in evaluating patients with high-risk cervical cancer to determine the most appropriate therapy, according to researchers from Stanford University in Stanford, CA.
