Radiation Exposure Causes Alterations Resembling Alzheimer’s

2016 31 Oct

A study published in the journal Oncotarget raises concerns that high levels of radiation may increase one’s chance of developing Alzheimer’s disease.   Increasing numbers of people of all ages are exposed to ionising radiation from a variety of sources, e.g. airline travel, nuclear technologies, medical diagnostics and therapeutic radiology. The use... Read more

Making Breast Screening Even Safer

2016 11 Jan

Digital mammograms pose only a small risk of radiation-induced breast cancer for most women, based on a modelling study conducted by an international team of researchers. However, the results show increased risk for women with large breasts or breast implants, who must often receive extra screening views, increasing their radiation exposure.Screening... Read more

Study: Unenhanced MR May Have Diagnostic Role

2015 29 Sep

Researchers in Germany say a novel magnetic resonance (MR) breast imaging technique could reduce unnecessary biopsies by providing additional information about suspicious findings on x-ray screening mammography. The technique is non-invasive, does not require a contrast agent and exposes the patient to no ionising radiation. Their work is reported in... Read more

Photoacoustics Used to Detect Breast Cancer

2014 21 Oct

Spanish scientists have developed a new type of laser technology based on photoacoustics that can be used for detecting breast cancer. The new technique is safe as no ionising radiation is used, and could become an alternative to commonly used diagnostic methods such as mammography and ultrasound, according to researchers from the Universidad Carlos...
