Spotting cancer mets before it’s too late

October 1, 2012 – 8:30 am

Nanotechnology could soon help oncologists spot the tiny breakaway cells that grow into potentially lethal metastatic tumours, "mets", in breast and other forms of cancer. Chain-like clusters of nanoparticles can sweep through blood vessels and latch on to any metastatic cells in the lining of blood vessels before these grow to untreatable sizes.

Fluorescence molecular tomography and magnetic resonance imaging (MRI) will allow oncologists and radiographers to see precisely where the mets are in the blood vessels and treat them before they start growing into tumours or reach vulnerable organs such as the liver and lungs.

Detecting mets to boost cancer survivability.

Acid in the brain

May 20, 2012 – 2:00 pm

Acid in the brain - University of Iowa researchers have developed an MRI-based method to detect and monitor pH changes in living brains. The new technique provides the best evidence so far that pH changes do occur with normal function in the intact human brain. The team hopes to use the method to investigate the role of pH changes in psychiatric disease, including anxiety and depression. The findings were published May 7 in the Proceedings of the National Academy of Sciences (PNAS) Early Edition.

Research offers new way to see inside solids

March 23, 2012 – 11:00 pm

Research offers new way to see inside solids - Researchers at Yale University have developed a new way of seeing inside solid objects, including animal bones and tissues, potentially opening a vast array of dense materials to a new type of detailed internal inspection. The technique, a novel kind of magnetic resonance imaging (MRI), creates 3D images of hard and soft solids based on signals emitted by their phosphorus content. The research, "quadratic echo MRI of solids," is published in the journal PNAS.
