John Mallard obituary
Medical physicist who pioneered body scanning as a way to diagnose diseaseFrom the earliest X-rays to the latest body scanners, the ability to visualise the inside of the living body has revolutionised medical diagnosis. With a profound understanding of physics, great technical ingenuity and a mission to put these skills to use in the service of medicine, John Mallard, who has died aged 94, was one of the first to establish routine scanning services that revealed tumours in organs such as the brain and the liver. His team at theUniversity of Aberdeen built the first whole-body MRI (magnetic resonance imaging) scannerand pr...

Hyperpolarized proton MRI used to observe metabolic processes in real time
(Johannes Gutenberg Universitaet Mainz) Magnetic resonance imaging (MRI) is already widely used in medicine for diagnostic purposes. Hyperpolarized MRI is a more recent development and its research and application potential has yet to be fully explored. Researchers have now unveiled a new technique for observing metabolic processes in the body. (Source: EurekAlert! - Cancer)

When peaking at your brain may help with mental illness
(University of Rochester) In recent years, researchers have begun using functional magnetic resonance imaging (fMRI) not just to better understand the neural bases of psychiatric illness, but also for experimental treatment of depression, ADHD, anxiety, PTSD, substance use disorder, and schizophrenia with real-time fMRI neurofeedback. But how well does it work? (Source: EurekAlert! - Medicine and Health)

Breast cancer screening recalls: simple MRI measurement could avoid 30% of biopsies
(Medical University of Vienna) Magnetic Resonance Imaging (MRI) is an accurate technique for detecting and classifying tumours in breast tissue. However, it sometimes causes " false alarms " , thus requiring further investigation (biopsy) and in some cases even resulting in so-called overtreatment, that is to say unnecessary surgery. For the first time, a research team from MedUni Vienna has now confirmed a threshold value for a non-invasive imaging biomarker. This can be incorporated into short standard MRI scans and could reduce the biopsy rate following MRI scans by 30%. (Source: EurekAlert! - Cancer)

Who Gets Pott ’ s Puffy Tumor?
Discussion
Pott’s puffy tumor (PPT) was first described by Sir Percivall Pott in 1775 and who also described other orthopaedic and oncological diseases subsequently named for him. “It is a subperiosteal abscess of the anterior wall of the frontal sinus associated with underlying frontal osteomyelitis.” The tender edema and swelling of the forehead is the sign of PPT. Associated fever, headache, and rhinorrhea along with similar problems such as postnasal drip or nasal congestion are common. Associated ophthalmological problems include peri-orbital or eyelid edema and/or preseptal cellulitis. Ptosis and di...

Politics and the brain: Attention perks up when politicians break with party lines
(University of Nebraska-Lincoln) Building upon previous work studying the brain and politics, Ingrid Haas, associate professor of political science affiliated with Nebraska's Center for Brain, Biology and Behavior, examined the insula and anterior cingular cortex in 58 individuals using functional Magnetic Resonance Imaging and learned that the human brain processes politically incongruent statements differently.

Damage to the heart found in more than half of COVID-19 patients discharged from hospital
(European Society of Cardiology) Around 50% of patients who have been hospitalised with severe COVID-19 and who show raised levels of a protein called troponin have damage to their hearts. The injury was detected by magnetic resonance imaging (MRI) scans at least a month after discharge, according to new findings published in the European Heart Journal. It is is the largest study to date to investigate convalescing COVID-19 patients who had raised troponin levels indicating a possible problem with the heart.

How comparable different stress tests are
(Ruhr-University Bochum) Scientists use many different tests to investigate what happens in the brain in people experiencing stress. It is unclear to what extent the various methods with which subjects are placed under stress are comparable to each other. In a meta-analysis, researchers compared 31 previous studies that had investigated stress using functional magnetic resonance imaging. The team worked out which regions of the brain are activated as standard during stress and which stress tests trigger similar activation patterns.
