An artificial intelligence tool that could help detect breast lesions likely to become cancer has been developed by researchers at MIT. When breast cancer is detected early, it can often be treated successfully. The best available test currently is the mammogram, but they are still imperfect and often result in false positive results that can… Read more

A noninvasive eye imaging technique can identify beta amyloid protein deposits that mirror those in the brain, a study led by researchers at Cedars-Sinai and NeuroVision Imaging LLC reports. The work provides a scientific basis for using the experimental technology to detect the pathological hallmarks of Alzheimer’s. Accumulations of neurotoxic beta-amyloid protein can be detected… Read more

Women who receive a false-positive mammogram result are newly prescribed anxiety or depression medication at a rate 10 to 20 percent higher than patients who receive an immediate negative result, new research shows. A false-positive result is one where a suspicious finding on the screening mammogram leads to additional testing that does not end up… Read more

A new nanodiamond-based contrast agent could improve visualization of liver cancer tumors. Contrast agents are chemical dyes that enhance the visibility of internal body structures in magnetic resonance imaging (MRI). MRI is commonly used for cancer diagnosis and to track the progress of patients after treatment. Currently, there are two modes of MRI imaging, T1-weighted… Read more

CT (computed tomography) scans are special medical X-rays that make three-dimensional pictures. These are very useful in the diagnosis and management of health conditions and injuries. Their potential downside is, the kind of radiation from CT scans (ionising radiation), causes DNA damage that can increase the later risk of cancer. Scientists have known for a… Read more
