Two studies on the use of breast MRI

Study Finds Use of Breast MRI in Women Increasing The overall use of breast magnetic resonance imaging has increased, with the procedure most commonly used for diagnostic evaluations and screenings, according to a study published by JAMA Internal Medicine, a JAMA Network publication. While breast MRI is being used increasingly, its sensitivity leads to higher false-positive rates and it is also more expensive…

Robots could one day help surgeons remove hard to reach brain tumors

A robot that worms its way in The median survival rate for patients with glioblastomas, or high grade primary brain cancer, is less than two years. One factor contributing to this low rate is the fact that many deep-seated and pervasive tumors are not entirely accessible or even visible when using current neurosurgical tools and imaging techniques. But several years ago, J. …

Sugar makes cancer light-up in MRI scanners

The new technique, called ‘glucose chemical exchange saturation transfer’ (glucoCEST), is based on the fact that tumours consume much more glucose (a type of sugar) than normal, healthy tissues in order to sustain their growth. The researchers found that sensitising an MRI scanner to glucose uptake caused tumours to appear as bright images on MRI scans of mice. Lead researcher Dr Simon Walker-Samuel, from the UCL Centre for Advanced Biomedical Imaging (CABI) said: "GlucoCEST uses radio waves to magnetically label glucose in the body. This can then be detected in tumours using conventional MRI techniques…

MRI detects early effects of chemotherapy on children’s hearts

Chemotherapy with anthracyclines, such as Doxorubicin, is one of the most effective treatments against many types of cancer, including leukaemia and Hodgkin’s lymphoma, breast, lung, and ovarian cancer. However it can also lead to irreversible heart damage, which may not be apparent until several years after treatment. Being able to detect this damage at an early stage, in order to initiate preventative therapy of affected people, is especially important in children. Researchers from University of Alberta performed MRI scans on children and young adults (aged 7 to 19) at the Stollery Children’s Hospital who were in remission following anthracycline treatment…
