Nonverbal doctor-patient rapport relieved pain during acupuncture treatment
When 22 acupuncture clinicians and 23 patients seeking pain relief mirrored each other's facial expressions during acupuncture treatment, patients experienced less pain, according to a new study. Additionally, brain activity involved in representing the mental state of others, which is key for empathy and compassion, became more aligned after the doctor and (2020-10-21)

Dual brain imaging provides insight into neural basis of patient-clinician relationship
Researchers from Massachusetts General Hospital have reported on an experiment using a novel magnetic resonance imaging-based approach to track the effects of different behaviors on the brain while patients and clinicians interact with one another. Their research, published in Science Advances, suggests that mirroring in both facial expressions and brain activity can affect the patient-clinician bond and treatment. In this case, the patients were receiving treatment for pain from an acupuncturist. (2020-10-21)

What lies between grey and white in the brain
A multidisciplinary team led by Nikolaus Weiskopf from the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) has succeeded in making the superficial white matter visible in the living human brain. (2020-10-19)

Body MRI reinterpretations plagued by discrepancies and errors
According to an article in ARRS' American Journal of Roentgenology (AJR), secondary interpretations of body MRI at tertiary care centers identify a high rate of discrepancies--with primary errors being interpretive in origin--suggesting that subspecialty interpretations should be encouraged, and institutions should provide adequate resources for these interpretations to occur. (2020-10-16)

Malice leaves a nasty smell
Unhealthy behaviours trigger moral judgments that are similar to the basic emotions that contribute to our ability to survive. Two different hypotheses are to be found in the current scientific literature as to the identity of these emotions. After developing a new approach to brain imaging, a research team from the University of Geneva shows that unhealthy behaviours trigger brain responses that are similar to those prompted by bad smells.

The benefits of a prostate cancer screening tool
Multiparametric magnetic resonance imaging of the prostate (mpMRIp) is a promising tool for diagnosing prostate cancer, and prior to its availability, detection relied on clinical exams and prostate specific antigen screening. (2020-10-07)

New method for in utero 4D imaging of baby hearts may aid diagnosis of congenital heart disease
Researchers at King's College London have developed a new method for helping detect congenital heart disease of a baby in pregnant mothers using MRI. Existing in-utero approaches are compromised by fetal motion, but the novel method corrects the motion to present 4D visualizations of the heart depicting major vessels and blood flow circulation. With further development, the method could become a new tool for aiding diagnosis of congenital heart disease where conventional methods like ultrasound might fail. (2020-10-05)

Deep learning helps explore the structural and strategic bases of autism?
Researchers have applied deep learning models to a vast collection of MRI brain scans of those known to have autism to identify the brain structures and dynamics of the condition in a way far beyond what humans could possibly assess. Don't worry about putting psychiatrists out of a job though! The technique should work as an incredibly useful aid to human doctors, not as their replacement. (2020-09-22)

A single-center observational study of more than 1,000 oncological examinations has demonstrated that positron emission tomography/magnetic resonance imaging (PET/MRI) facilitates cancer staging as well as PET/computed tomography (PET/CT) and improves lesion detectability in select cancers, potentially helping to promote fast, efficient local and whole-body staging in one step. (2020-09-17)

Artificial intelligence helps cut down on MRI no-shows
According to ARRS' American Journal of Roentgenology, artificial intelligence predictive analytics performed moderately well in solving complex multifactorial operational problems--outpatient MRI appointment no-shows, especially--using a modest amount of data and basic feature engineering.

Future mental health care may include diagnosis via brain scan and computer algorithm
Most of modern medicine has physical tests or objective techniques to define much of what ails us. Yet, there is currently no blood or genetic test, or impartial procedure that can definitively diagnose a mental illness, and certainly none to distinguish between different psychiatric disorders with similar symptoms. Experts at the University of Tokyo are combining machine learning with brain imaging tools to redefine the standard for diagnosing mental illnesses. (2020-08-17)

Waistline matters in kidney disease
Does fat matter in kidney disease? The investigators found that all measures of higher abdominal fat content (including visceral fat, liver fat, or subcutaneous fat) and slower walk times were associated with increased levels of cardiometabolic risk factors in adults with non-dialysis dependent kidney disease. These data highlight that abdominal fat measures and lower physical fitness levels are associated with a higher cardiovascular risk in adults with non-dialysis dependent kidney disease. Waist circumference may be a new vital sign. (2020-08-13)

Patient experiences in medical imaging and radiation therapy: The importance of skilled patient care professionals

Effect of gadolinium-based contrast agent on breast diffusion-tensor imaging
An ''Original Research'' article published in ARRS' American Journal of Roentgenology (AJR) concluded that the accuracy of breast cancer diagnosis via diffusion-tensor imaging (DTI) was equivalent both before and after the administration of a gadolinium-based contrast agent (GBCA), despite a value change in DTI parameters. Due to the lack of standardization of contrast-enhanced DTI, the authors of this AJR article still preferred unenhanced diffusion measurements. (2020-08-06)

Scientists suggest device to make breast MRI more effective
Magnetic resonance imaging is becoming increasingly popular as a method of diagnosing diseases. Standard scanners are multifunctional, making it possible to cut down on the costs of specialized equipment. On the other hand, this leads to images of lower quality, especially when relatively small areas need to be examined. A group of Russian scientists, including ITMO University researchers, has proposed a system that can be used to update existing MRI scanners. It will allow conducting breast MRI using standard scanners without specialized equipment. (2020-08-04)

'Little brain' or cerebellum not so little after all
When we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example. High-res imaging shows the cerebellum is 80% of the area of the cortex, indicating it has grown as human behavior and cognition evolved. (2020-07-31)

UAlberta researchers make real-time tumor tracking in radiation therapy 5 times faster
A team of University of Alberta researchers has developed a faster way of tracking the movement of tumors in the body during radiation therapy, which could significantly improve outcomes for cancer patients. The team's work builds on the Linac-MR project, a radiation beam (linear accelerator or 'linac') and magnetic resonance imaging (MRI) hybrid machine developed by researchers at the Cross Cancer Institute in 2013. (2020-07-22)

UCalgary research study finds MRI effective in predicting major cardiac events
An international study led by Dr. James White, a clinician and researcher at the University of Calgary finds magnetic resonance imaging can be used to predict major cardiac events for people diagnosed dilated cardiomyopathy. White's study confirms about 40 per cent of patients with DCM have scarring patterns on their heart muscle which can be seen with MRI. These patterns are associated with higher risk of future heart failure admissions, life-threatening heart rhythms and death. (2020-07-15)
