Published November 1, 2026. A study published in npj Digital Medicine on October 21 evaluates two commercial pulmonary embolism detection algorithms across a 17-facility academic health system. Mansuri and colleagues retrospectively examined 30,678 CT pulmonary angiography examinations and 37,191 routine contrast-enhanced CT examinations using Aidoc Medical BriefCase algorithms. Reference labels came from radiology reports processed […]
Published November 1, 2026. A systematic review published in npj Digital Medicine on October 23 examines whether clinicians detect and resist incorrect automated advice. Zeng and colleagues identified 46 reports representing 41 independent cohort clusters, including 40 core cohorts. Across three adjusted cohorts, clinician correctness was substantially higher when automated advice was correct rather than […]
Published October 31, 2026. A brain imaging study published in Communications Biology on October 26 explores how anatomical connections relate to functional brain networks in autism. Kim and colleagues analyzed imaging from 91 autistic individuals and 67 typically developing controls. They used mathematical modeling to predict functional connectivity from structural networks while considering communication over […]
Published October 31, 2026. A multicentre study published in npj Digital Medicine on October 26 compares AI approaches combining PSMA PET/CT and multiparametric MRI to identify clinically significant prostate cancer. Chen and colleagues used paired imaging and biopsy-confirmed labels from 527 patients at three hospitals. Models were developed using 363 patients at one centre and […]
Published October 31, 2026. A mouse study published in Nature Neuroscience on October 27 examines how the hippocampus can distinguish individual experiences while carrying useful knowledge into new situations. Tang, Chang and colleagues analyzed the collective activity of hippocampal neurons during behavior. Although individual cells showed varied and changing responses, groups of cells organized information […]
Published October 31, 2026. A human single-neuron study published in Nature Neuroscience on October 27 links activity in the amygdala to whether newly viewed pictures are subsequently remembered. Xiao and colleagues examined two memory-task datasets collected during intracranial monitoring for drug-resistant epilepsy. Neurons selective for particular image categories fired more strongly while participants viewed pictures […]
Published October 31, 2026. A study published today in Scientific Reports examines how sleep-related brain signals change over a night. Ghosn and colleagues applied automated quantitative EEG analysis to 10,000 high-resolution overnight polysomnography cases, comparing the first, middle and last occurrences of each sleep stage. Across all sleep stages, power in the 1–20 Hz range […]
Published October 31, 2026. An accelerated MRI protocol produced broadly comparable quantitative susceptibility maps in 36 memory-clinic patients, according to research published today in Scientific Reports. Quantitative susceptibility mapping, or QSM, measures magnetic properties influenced by iron and other tissue constituents. The researchers compared a standard SENSE acquisition with a faster CS-SENSE protocol during 3-tesla […]
Published October 31, 2026. A study published today in Scientific Reports tested whether an early cortical stroke worsens Alzheimer’s-related changes in a mouse model. Under the conditions examined, researchers did not detect additional pathology or cognitive impairment in the transgenic animals. Permanent middle cerebral artery occlusion was induced at four months of age in wild-type […]
Published October 31, 2026. A study published October 30 in Nature Communications links changes in REM sleep brain waves with aging, Alzheimer’s-related pathology and overnight forgetting. Across two independent cohorts, researchers observed a shift from faster sawtooth delta waves toward slower, NREM-like delta waves with age, particularly during phasic REM sleep. The shift was associated […]
