MRI confirms prostate cancer with lower dose of GBCA
December 14, 2017 -- MRI scans with a reduced dose of a gadolinium-based contrast agent (GBCA) can be more effective than scans with a standard dose in differentiating between malignant and benign lesions in prostate cancer patients, according to a study presented recently at RSNA 2017.  Discuss
fMRI, PET could help foresee epileptic seizure issues
December 12, 2017 -- Researchers have developed a method to integrate functional MR (fMRI) and PET images to identify epilepsy patients who are at high risk of continued seizures before the patients undergo potentially unsuccessful surgery, according to a study published online December 5 in Frontiers in Neuroscience.  Discuss
PET/MRI outclasses MRI alone for pelvic cancer recurrence
December 11, 2017 -- PET/MRI can better detect and classify local lesions and distant metastases in women suspected of having recurrent pelvic cancer than MRI alone, according to a study presented at the recent RSNA 2017 annual meeting.  Discuss
SABCS: Biannual breast MRI best for young women at high risk
December 11, 2017 -- For young women with a high genetic risk of breast cancer, twice-yearly MRI exams are more effective for detecting early disease than an annual mammogram, according to new research presented at the 2017 San Antonio Breast Cancer Symposium (SABCS).  Discuss
