In a new study, led by the University of Glasgow, scientists show that brain activity recorded using functional magnetic resonance imaging (fMRI) may help predict response to CBT in depression before the treatment commences. The advances could help patients receive the most appropriate treatment for depression in a timely manner.
For patients with kidney failure who need dialysis, removing fluid at the correct rate and stopping at the right time is critical. This typically requires guessing how much water to remove and carefully monitoring the patient for sudden drops in blood pressure. Currently there is no reliable, easy way to measure hydration levels in these patients, who number around half a million in the United…

The speed of the human brain is remarkable. Almost immediately upon being exposed to stimuli, neurons are activated, prompting subconscious reactions and, a fraction of a second later, thought. But the speed at which we can noninvasively follow brain function using an MRI is not as impressive. Functional MRI (fMRI), which measures changes in blood-oxygen levels, has revolutionized neuroscience by…
Researchers at the University of North Carolina School of Medicine used MRI brain scans and machine learning techniques at birth to predict cognitive development at age 2 years with 95 percent accuracy. “This prediction could help identify children at risk for poor cognitive development shortly after birth with high accuracy,” said senior author John H. Gilmore, MD, Thad and Alice Eure…
Despite COCIR raising the alarm as early as 2014, the age of the installed base of medical imaging equipment in Europe continues to increase. To draw attention to this worrying trend, COCIR is presenting new data on the current situation in four modalities of medical imaging, graphically demonstrating the extent of the issue. These were launched tday at the European Congress of Radiology 2019 in…
Technological change is a major part of change management in radiology and it is inevitable. Artificial intelligence (AI) has slipped into every area of life including the hospital, and is already making decisions in radiology systems. The good news is that radiologists could win on two fronts, provided they play their cards well, a leading USA radiologist told delegates at a recent congress in…
Ultra-high-field magnetic resonance tomography with field strength of 7 Tesla is slowly but surely entering clinical routine. ‘Thanks to very high spatial and spectral resolution, ultra-high-field MR permits detailed views of the human anatomy and can show precisely the metabolic processes such as those in the brain,’ said Professor Siegfried Trattnig, from Vienna’s Medical University.
New medical software which overlays tumour information from MRI scans onto ultrasound images is helping to improve detection of prostate cancer by guiding surgeons as they conduct biopsies. Developed at University College London (UCL), the software is deployed via a system called SmartTarget and embraces artificial intelligence (AI) to use both systems in tandem to enable surgeons to pick up…

Tattoos are increasingly popular. Every eighth person in Germany has already felt the sting of getting a tattoo. A recent representative survey of the Federal Institute for Risk Assessment (BfR) revealed that nearly 90% of tattooed individuals considered them harmless to one’s health. Yet, if tattooed people are to be examined with magnetic resonance imaging (MRI), the question often arises of…
In his talk at the Garmisch Symposium, entitled “MRI in 5 minutes – Dream or Reality?” Dr. Daniel Sodickson of the New York University School of Medicine will give attendees a preview of the MR scanners of the future, which he likens to self-driving cars. Sodickson — a professor and vice chair for research in the department of radiology at NYU, a principal investigator at the Center…
Magnetic resonance imaging (MRI) exams of the knee are essential to orthopedic surgeons for diagnosing the cause of symptoms in patients with knee pain and planning arthroscopic treatment. Yet the surgeons who treat patients based on knee MRIs and the radiologists who interpret those knee MRIs often work in their own silos of specialization, rarely communicating and sharing information, according…
Brain imaging in patients with cognitive complaints need to be viewed differently when using MRI to diagnose and treat patients with dementia, says Dr. Christopher Hess, who will discuss the role of MRI in the adjunctive diagnosis of dementia in his talk at the Garmisch Symposium.
