A new study, published in the journal Investigative Radiology , indicates that repeated use of specific “linear”-type gadolinium-based contrast agents (GBCAs) — widely used for diagnostic MRI scans — can lead to deposits of the heavy-metal element gadolinium in the brain. The findings could have a major impact on the multimillion-dollar market for...Read more

Researchers at MedUni Vienna have used a new magnetic resonance imaging (MRI) technique to classify adenomas — rare liver tumours — without subjecting patients to invasive tissue sampling procedures. This type of tumour, the researchers say, can now be clearly classified by means of a liver-specific MR contrast agent called gadoxetic acid. Although...Read more

Using a powerful 9.4-Tesla MRI — the first of its kind for human imaging — researchers at the University of Illinois at Chicago have obtained the most detailed MRI images of the brain so far to show that while the brain shrinks with age, brain cell density remains constant. The findings are reported in the journal NMR in Biomedicine . The 9.4-Tesla...Read more

Duke Medicine researchers have created a 3D map of the human brain stem at an unprecedented level of detail using MRI technology. In a report published in Human Brain Mapping , the researchers say the new 3D model would be useful to brain surgeons treating conditions such as tremors and Parkinson’s disease with deep brain stimulation (DBS). Many...Read more

Results of a new study tend to support the prevalent opinion among physicians specialising in sports-related concussion (SRC) that neuroimaging is not that useful in diagnosing SRCs. Researchers from the Canada North Concussion Network in Manitoba examined neuroimaging studies in children and adolescents with SRCs and found that the images appeared...Read more

A novel tiny drug-delivery system — so far tested in mice — can identify cancer cell types in the brain through “virtual biopsies” and then attack the molecular structure of the disease, according to researchers from Cedars-Sinai. If results are confirmed in human studies, the system could be used to deliver nanoscale drugs that can distinguish and...Read more

A simple blood test to measure brain-specific proteins released after a person suffers a traumatic brain injury (TBI) has been shown to predict both evidence of TBI on radiographic imaging and injury severity. A multicentre study, published in Journal of Neurotrauma , describes the potential benefit of adding detection of glial fibrillary acidic protein...Read more

Researchers at University of Gothenburg (Sweden) say a new method that combines a traditional PSA test with an MRI can detect a significantly greater number of prostate cancer cases and improve diagnostic accuracy. They conducted the study as part of the largest international research project on prostate cancer. Based on 384 Swedish subjects, the study...Read more

According to a new study conducted by a team of scientists from Cardiff University Brain Research Imaging Centre (CUBRIC), the Institute of Psychiatry, Psychology and Neuroscience, Kings College London and the University of Bristol, new scanning methods could be used to predict people at risk of schizophrenia. The results have been published in the...Read more

Researchers at Kobe University (Japan) have developed a new surgical clip — 5 mm in size and made of a magnesium alloy — that dissolves and is absorbed by the body after a certain period of time. Their in vivo experiments showed that the surgical clip can reduce the rate of postoperative complications and minimise problems associated with diagnostic...Read more

Neuroimaging is an important diagnostic tool in the assessment of neurological disease, but often unmasks incidental findings (IFs). The negative impacts of IFs, such as patient anxiety, present neurologists with management dilemmas, largely due to the limited knowledge base surrounding the medical significance of these IFs. Specifically, the lack of...Read more
