...l tissue, differences that can often be subtle and obscured by densities in the surrounding breast tissue. "Approximately 25 to 40 percent of women have dense breast tissue, which decreases the chance that a cancer will be visible on their mammograms," says Douglas Collins, M.D., a Mayo Clinic radiologist, wh...3D neutron-based medical imaging, 4D lung scans, and hitting a moving tumor

Contrast imaging involves the injection of an agent, such as iodine (in x-ray imaging) or gadolinium (in MRI), that concentrates in abnormal breast tissue and "lights up" those regions in subsequent imag...Advice for designing reliable nanomaterials
